"An improved fuel cock assembly for Automobiles"
Advik Hi-Tech Private Limited Gate No.357, plot No.99,Part A, Chakan-Talegaon Road, PUNE410 501. Maharashtra State, India An Indian Company registered under the provisions of Companies Act, 1956.

The following specification particularly describes the nature of the invention and the manner in which it is to be performed: -


Present invention relates to an improved fuel cock assembly for automobiles. More particularly present invention relates to the fuel cock assembly for automobiles having a specially provided cylindrical rubber bush which acts as a seal, imparts more surface area and controls the leakage of fuel; loss of fuel due to evaporation and enhances the life of the fuel cock.
In prior art, in two or three wheelers, the fuel cock assembly for automobiles is having a flat seal, which is kept, in position with the hole in the body and over the said seal lever is rotating. Position of the lever makes way for the fuel connection to 'ON' and 'RES' position of the lever. The rubber seal has a button projection for sealing the fuel. Thus the area of contact in the fuel assembly is very much less than required which leads to leakage and evaporation of fuel over a period of time and comparatively less life.
Object of the present invention aims at developing a fuel cock assembly for automobiles, which avoids wastage of fuel due to leakage and evaporation.
It is also the object of the present invention to develop a fuel cock assembly for automobiles having long life and and evaporation control.
According to the most salient feature of the present invention the fuel cock assembly for automobiles is specially provided with a cylindrical rubber bush which acts as a seal, imparts more surface area and controls the leakage of fuel, loss of fuel due to evaporation and enhances the life of the fuel cock.
According to this invention, therefore, an improved fuel cock assembly for automobiles comprising of the main body with taper, characterised in that there is provided a cylindrical rubber bush in the flange portion of the main body having a provision of two holes at 90 degree apart, the said bush is provided with a taper to match the taper provided in the said main body, the connector output is press-fitted to the said main body for fuel to flow out; the lever is inserted in the said bush; the said

lever is provided with a radial hole and an axial hole interconnected tor fuel to flow out.

The invention will specification wherein the refereed to appropriately in
now be described with the help of drawings accompanying this salient features have been shown by suitable numerals and the following description.

The lever (7) is (refer fig.3). The said axial said lever (7) is inserted in &3) placed on the outer
provided with one hole (7a) radially and one hole (7b) axially. and radial holes are interconnected for fuel to flow out. The the said cylindrical bush (6) with the 'O' ring (8) (refer figs.2 diameter of the lever for face sealing of the fuel. The said

cylindrical bush (6) acts as a radial sealing of the fuel. The rotation of the said lever (7) is restricted to 180 degree by the plate (9). The plate is provided with a profile as shown in fig. to control the movement of the lever to 180 degrees only. Arrangements are being made such that, during the movement of the said lever (7) the radial hole (6a) in the bush (6) matches with the radial hole (7a) of the said lever and the said main body (1) and any of the holes, one at a time and allows the fuel flow from the tank depending upon the movement of the said lever (7a). Every 90-degree movement of the lever will be in "RES' 'OFF' & 'ON' position. Alternately it can be 'ON', 'OFF' & 'RES' also. These positions are indicated on the plate. The plate is held in position on to the said main body (1) flange by two screws fastened to or riveted to the said main body (1). Details of the components in the fig: -Main body (1).

1. Leakage of the fuel is eliminated.
2. Evaporative emission is better.
3. Emission of hydrocarbon to atmosphere because of evaporation is controlled.
4. Saving of fuel.
5. Life of fuel cock is enhanced.
