DESC:FIELD OF THE INVENTION:
The present invention relates an easy to install screw on tyre valve stem for a pneumatic tire and more particularly, it relates to a tyre valve stem with two ports for inflating and deflating pneumatic tire bladder without removing TPMS sensor (tire pressure monitoring system sensor) from the Existing Tyre Valve.

DESCRIPTION OF THE RELATED ART:
Automobiles are undoubtedly the most important transportation means for the modern times. Therefore, the contemporaries put increasing attention to car safety. Among others, appropriate tire pressure is essential for safe and smooth driving. As compared with properly filled tires, low-pressure tires can consume more fuel during driving and increases tyre wear and make it more difficult for a driver to control the direction where a car proceeds, wherein the latter in particular endangers the driver and his/her passengers in car.
Recently, there have been many tire pressure monitoring devices on the market. In conventional tire pressure monitoring device, it comprises a valve stem fixedly being configured to be set in a valve-stem hole formed on a tire wheel rim and work with a bolt as well as a nut to affix the stem body to the tire wheel rim, so that said body is allowed to monitor the tire pressure during driving all the time and warn the driver with a signal when the tire pressure is detected as abnormal.
However, said presently existing tyre pressure sensor systems have some drawbacks. When the tyre pressure sensor is installed on the inflation valve at the internal side, the tyre pressure sensor has to be removed first prior to the inflation and in case of tyre puncture. Nevertheless, the removal is much inconvenient since the tyre pressure Sensor is disposed next to the external tyre and therefore only little free room is available. In addition, it brings also difficulties to re-screw the tyre pressure Sensor in position when each inflation operation is completed. Thus, it adds complexity to the placement of the assembly in the rim. To carry out the above-mentioned operation within such a narrow space between the internal and external tyres does consume much time and cost. Further, frequent opening of sensor may results into the damage during installation. This doesn't fulfill the requirement of the economic benefit. Also during topping up of Air the sensor has to be removed repeated again and again to check the tyre pressure till right tyre pressure is achieved.

An improved inflation valve is therefore needed for getting rid of the existing cumbersome procedure.
OBJECT OF THE INVENTION:
The main object of the present invention is to provide a tyre valve stem with two ports that is free from the drawbacks associated with conventional tyre valve stem.

Another object of the present invention is to provide a tyre valve stem that enable the user to inflate and deflate the pneumatic tyre without removing the pressure sensor from the Tyre Valve.

Further object of the present invention is to provide a tyre valve stem that is provided with two ports, first port via which air is permitted to introduce into the tyre and second port for receiving pressure sensor.

The main object of the present invention is to provide an easy means of installation of tyre valve, which saves time, Cost and doesn’t require to remove the tyre valve for valve stem installation and further doesn’t require to remove the external TPMS Sensor for inflating/deflating the tyre pressure.

SUMMARY OF THE INVENTION:
The present invention relates to a tyre valve stem with two ports for inflating and deflating pneumatic tire bladder without removing tire pressure sensor from the Valve. According to present invention, said tyre valve stem is to be screwed on the existing (Original) Tyre valve. The valve stem comprising a valve body having first and second end portion. Said first end portion is extended into the inflation screwed on the existing (Original) Tyre valve. Said second end portion has an inflation/deflation port and a TPMS Sensor port. Said inflation/deflation port is configured for supporting an air pressure valve for permitting air to introduce in the tire and for discharging air from the tire. Said TPMS (tire pressure monitoring system) Sensor port includes a tyre pressure monitoring system Sensor that is configured to sense and transmit the air pressure level of the tyre to the display module through which driver of the vehicle can continuously monitor the pressure of each tyre.

Thus, by adapting separate ports for inflating tyre and for sensing tyre pressure, it is not required to remove the pressure sensor during the inflation of tyre and the screw on installation method makes it very convenient to install the valve stem without removing the existing tyre valve.

DETAILED DESCRIPTION OF THE INVENTION:

The present invention overcomes the aforesaid drawbacks and the above and other objects, features and advantages of the present invention will now be described in greater detail. Also, the following description includes various specific details to assist in that understanding but these specific details are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that: without departing from the scope and spirit of the present disclosure, various embodiments may be various changes and modifications described herein.

The present invention discloses a tyre valve having a two-port valve stem with an elongated body of hollow configuration. First end of said valve is to be screwed on the existing (Original) Tyre valve. Second end of the valve stem is configured with two ports, an inflation/deflation port and a TPMS Sensor port, being approximately formed in perpendicular configuration with respect to each other. Said inflation/deflation port and the first end portion of the valve stem are aligned with each other in an axial direction while the TPMS Sensor port is arranged transversely. Further only , inflation/deflation ports include the actuating pin with resilient means through which air is permitted to be introduced into the tyre and prevent air from escaping from the tyre and the TPMS sensor port also includes actuating pin on which TPMS Sensor is installed.
Now according to present invention, said TPMS port includes a tyre pressure monitoring system. Said tyre pressure monitoring system includes at least one tyre pressure sensor means to measure air pressure in the tyre, a wireless receiver for receiving tire pressure signals transmitted from the sensing units, a wireless transmitter being connected to the wireless receiver via a signal line, so as to receive tire pressure signals from the wireless receiver and wirelessly transmit integrated tire pressure signals to a display module being mounted within the vehicle for receiving and displaying the tire pressure signals transmitted from the wireless transmitter.

Said display module includes at least a wireless receiver, a power supply, and a display panel. Said wireless receiver being adapted to receive tire pressures signals transmitted from said wireless transmitter and said display panel being adapted to directly indicate the tire pressures of said tires being monitored. Further, said power supply supplies power needed by said wireless receiver and said display panel.

Said pressure sensor is fluidly communicated with inflation cavity of the wheel, the inflation cavity being typically defined by the wheel rim and a tubeless tire. The pressure sensor senses the conditions inside the tire and wirelessly transmits the sensed data to the display module mounted in the vehicle where the indicator light illuminates. Said tire pressure monitor sends all of this data wirelessly through the RF transmitter. Each sensor has a unique serial number and accordingly pressure readings for each individual tire are indicated on the display module. Thus, it continuously delivers real-time tyre-pressure readings from inside the tire to the driver of the vehicle.
Another port, the inflation/deflation port is configured to relieve pump air into the inflation cavity or to release the pressure. The inflation valve may be opened, and permit compressed air to enter into the inflation cavity and thus inflating the tyre. This allows the tyre to inflate with highly compressed air. Thus, user can introduce air in the tyre or remove air without manipulating the TPMS Sensor system.
Thus, by the configuration of two separate ports, cumbersomeness of removal of pressure sensor at time of inflation/deflation of tyre pressure is avoided. The Said Valve Stem has inner threads which screws on the existing original valve with the help of anti – theft nut, which further makes it very easier to fit the valve stem and prevents the theft.
Due to aforesaid configuration, it is not required to remove the pressure sensor while inflating/deflating the tyre. Simultaneously making it easier to just screw on the valve Stem system on the existing valve. Further, according to present invention, the body of the valve stem is preferably made from, but not limited to, brass that make the substantially rigid construction of valve body with light weight and enough strength.
Referring to figure there is schematically illustrated a two-port tire valve assembly. The two-port valve stem 10 has an elongated body 11 of hollow configuration. The hollow body 11 is on original existing valve 12 and a second end portion 13. The First end Portion of 46 the two-port valve is to be screwed on the Original existing valve 12. The Second end portion 13 has a first port 22 and a second port 32 arranged in a branch configuration. The Ports 22 and 32 are integral parts of the body 11 of the valve system 10. The first port 22 is spaced apart from the second port 32. The first port 22 and the first end portion 46 of the valve stem are aligned with each other in an axial direction while the second port 32 is arranged transversely, for example in perpendicular relation, to the first port 22 and the first end portion 46 of the valve stem 10 there by creating a T-shaped valve system. In another embodiment, the valve stem and the two ports may form a Y-shaped valve stem, and in yet another embodiments any other suitable shape of the valve stem or alignment of the ports may be used. For Example the first end portion 46 and the first port 22 and the second port 32 may not all be aligned in the same plane. Angles between the first end Portion 46 and the first port 22 and the second port 32 may be acute, right or obtuse. The body 11 may be straight curved or bent.

In one embodiment the valve stem 10 is a metal valve system. The Valve assembly includes a first valve 20 with an actuating pin 14 located within the first port 22 and a second valve 21 with an actuating pin 24 located within the second port 32. The pins 14 and 24 permit air to be introduced into the tire and prevent air from escaping from the tire through the valve system 10 and ports 22 and 32 respectively. By pressing on either of the pins 14 and 24, air from the volume enclosed by the tire may be released from it. The valves 20 and 21 may be Schrader valves, which may be pre-assembled in ports 22 and 32 of the valve stem 10, or may be assembled within the ports 22 and 32 of the valve stem 10 by a user or service technician. Other types of valve may also be used. The valve stem 10, containing Schrader or other valves, may be provided as an assembly.

The Valve Stem 10 is to be screwed on original existing valve 12, which will be secured with antitheft lock nut 45. Tire Pressure Sensor 42 to be mounted on second port 32 which is secured with antitheft check nut 47, however the pressure sensor 42 may be mounted on either port of the valve stem 10. The Pressure sensor 42 has a housing 43, which is adapted to be screwed onto the open end of the second port 32. The Pressure sensor 42 also has also has a penetration pad 44 disposed within the housing 43 protruding outwardly such that penetration pad 44 presses against the actuating pin valve 24, forcing it inwardly within the second port 32 as the housing 43 is screwed onto the second port 32 so that the interior of the pressure sensor 42 is placed in fluid communication with the interior of the hollow body 11 of the valve stem 10 and the tire, meaning that a portion of the air from the tire enters the pressure sensor 42. A metal or plastic valve cap 40 screws onto the open end of the first port 22 and protects the interior of the first valve 20 as well as threaded end of port 22.

The Pressure sensor 42 is removed from the two-port valve stem 10, then the valve pin 24 of the second valve 21 will move outwards preventing the escape of air from the tire. This feature is useful to facilitate the cleaning; maintenance, testing and battery changing of the pressure sensor 42 while removed from the wheel and without necessitating a complete re-fill of air in the tire.

The Port 46 is screwed on the existing valve 12 and is secured with an AntiTheft Check nut 45. Port 46 is embedded with a valve and actuating pin 48. When the port 46 is screwed on existing valve 12 the actuating pin 48 presses the actuating pin of existing valve and the tire pressure is transmitted into the port assembly 49. Port 46 has inner threads which screws on the stem of existing valve 12. The two port tyre valve system can be pre-assembled with sensor on port 32 and can be easily screwed on the existing valve 12.
