DESC:The invention will now be described with reference to the accompanying drawings which do not limit the scope and ambit of the invention. The description provided is purely by way of example and illustration.
Figure 1 illustrates a side perspective view of the first embodiment of a shock absorber cooling device 2(not shown) in accordance with the present invention placed on a two-wheeler vehicle and is generally indicated by reference numeral 100. The intention of the current invention is to keep the temperature of the shock absorber 1(not shown) within safe working limits and hence the device can be placed in the vicinity of the shock absorber 1(not shown) within the available space without requiring a large space to get assembled. The device sucks in air from the surrounding of the vehicle for which it requires a narrow vent 5 in the frame 6 of the two-wheeler. The vent 5 can be placed anywhere in the frame 6 of the two wheeler in the vicinity of the shock absorber cooling device 2(not shown) and is flexible with respect to its placement. An opening 3(not shown) connected internally to the vent 5 pushes sucked in air towards the shock absorber 1(not shown) to effectively cool it. In this embodiment of the present invention no external power is required to operate the shock absorber cooling device 2(not shown). The opening 3 can be varied to a lower cross sectional diameter as compared to the cross section of the vent 5 to maximize the effect of cooling of the shock absorber 1 through venturi effect.
Figure 2 illustrates a top perspective view of second embodiment of the present shock absorber cooling device 2 in accordance with the present invention and is generally indicated by reference numeral 200. As shown in the figure 2, a shock absorber 1 is placed in a two-wheeler. Continuous operation of the vehicle increases the temperature of the oil in the shock absorber 1 which affects the damping characteristics of the shock absorber 1 for which a shock absorber cooling device 2 has been placed near the shock absorber 1. The shock absorber cooling device uses a battery operated fan 4 for the purpose of sucking in air from the surrounding of the vehicle by a fan opening 4A while the vehicle is in operation. The battery operated fan 4 and the fan opening 4A is connected to the opening 3 of the shock absorber cooling device 2. The opening 3 has a unique construction to take the advantage of venturi effect. As the air passes through the constricted section of the opening 3 the air experiences a drop in pressure which is balanced by an increase in its velocity thereby pushing the air towards the shock absorber 1 at a higher velocity v2 as compared to the intake velocity v1 of the air sucked in by the battery operated fan 4 from the fan opening 4A. This air at a higher velocity v2 is pushed towards the shock absorber 1. The drop in the pressure near the opening 3 creates a suction zone which sucks in more ambient air from the air port 11 and the vicinity of the shock absorber 1, which in turns increases the total air intake of the shock absorber cooling device 2. This air together falls on the shock absorber 1. Consequently the shock absorber cooling is increased by a factor of around 15-20 times. The shock absorber cooling device 2 also works on the same principle while the vehicle is at rest wherein intake of air is through the fan opening 4A. The opening 3 can be varied to a lower cross sectional diameter as compared to the cross section of the fan opening 4A to maximize the effect of cooling of the shock absorber 1 through venturi effect.
Figure 3 illustrates a side perspective view of second embodiment of the present shock absorber cooling device 2 in accordance with the present invention and is generally indicated by reference numeral 200. As shown in figure a shock absorber 1 is placed on the bottom end portion of the frame 6 of the two wheeler vehicle. The shock absorber cooling device 2 having an opening 3 oriented towards the shock absorber 1 is placed in the vicinity of the shock absorber 1 and air port 11. The shock absorber cooling device 2 has a battery operated fan 4 that sucks in air from the surrounding of the vehicle through fan opening 4A and pushes the air towards the shock absorber 1. Also the opening of the shock absorber cooling device sucks in air from the air port 11 and the vicinity of the shock absorber 1 due to the motion of the vehicle apart from the one entering the device due to the operation of the battery operated fan 4 through fan opening 4A. As shown in the figure the shock absorber cooling device 2 does not require large space and is easily adaptable to the existing vehicles. The opening 3 can be varied to a lower cross sectional diameter as compared to the cross section of the fan opening 4A to maximize the effect of cooling of the shock absorber 1 through venturi effect.
Figure 4 illustrates a top perspective view of the third embodiment of the present shock absorber cooling device 2 in accordance with the present invention and is generally indicated by reference numeral 300. As shown in the figure an air hose 7 with varying cross-section has been used to generate cooling effect of the shock absorber 1. The apparatus here takes the advantage of the air flow due to the motion of the vehicle. The air coming in the opposite direction as that of the vehicle enters through the grilled nozzle opening 8 and falls on the shock absorber 1 via the opening 9 of the air hose 7. This grilled nozzle opening 8 rests on the leg guard 10 and the air hose 7 and opening 9 are adequately supported on the frame of the two-wheeler. The cross sectional diameter of the air hose 7 can be varying accordingly to increase the cooling effect as required.
Figure 5 illustrates a perspective view of the cross-section of the venturi shaped opening present in the shock absorber cooling device 2 in accordance with the present invention. A portable venturi shaped structure is provided which draws in ambient air and forces the said ambient air on to the shock absorber 1 for effective cooling. The venturi shaped structure has an opening which takes in air from either a fan opening 4A or an external vent 5. The air sucked in by the battery operated fan 4 would increase the intake of the venturi by a factor of around 15 to 20 times of its intake owing to the venturi effect. As a result, with a small opening, a larger volume of air could be impacted upon the shock absorber 1 for effective cooling. Further, if the air intake is placed along the two wheeler, the wind resistance can also provide air form the vent for effective venturi action as stated above.
It will be appreciated form the foregoing description that various other embodiments of the above mentioned device are possible without departing from the scope and ambit of this invention.
