Abstract: The present invention comprises a flexible heat exchange assembly for heating and thermal control the surface of a seat that is designed to prevent the blockage of fluid flow due to the pressure of an occupant's weight, which generally consists of formed layers that create passages through which a heat exchange fluid flows. The upper surface seat cushioning material is formed such that there are recesses into which these fluid passages rest, thereby preventing the blockage of fluid flow when the pressure from the weight of an occupant deforms the cushion.

Abstract: The present invention provides a method and system for cooling a seat 14 surface, comprising at least one cushion, plurality of flexible metallic heat exchangers and optionally a cushioning layer. The metal heat exchangers are thin flexible metal sheets 18a, 18b with high thermal conductivity and a preferable thickness in the range of 0.05 mm and 10 mm. These are incorporated in the cushion, wherein the conduit is bonded, soldered or brazed to thin flexible metal sheet 18a, 18b acting as continued or intermittent conduit, with fluid, for cooling the metallic heat exchangers. The present system allows lowering of the total temperature difference improving the coefficient of performance of the refrigeration system that supplies the cooled fluid, leading to a smaller, lighter cold water supply system that also consumes less power and performs direct cooling of an occupant's body.

Abstract: The present invention, sealing element that dampens the acoustics of the dual path dual purge valve assembly is provided, that is incorporated into the valve itself, further the element shall absorb the kinetic energy of the impact and prohibit the sound transmission, due to its unique shape, configuration, angle, and placement, thereby obviating additional requirements of any type of decoupling devices. Further, the invention modifies dual purge valve assembly, to adequately and securely, install the sealing element. The sealing element is installed on the big moving core, which reduces the noise from touchdown.

Abstract: The invention provides an sliding contact single vane rotary vacuum pump in which an oil supply passage is placed in the centre of the rotating vane through which a lubricating oil flows, which provides oil distribution in the pump chamber with enhanced suction pressure of 39%; and the torque exertion by 2.86-7.63%, this helps in reducing the torque of the pump during maximum vacuum condition and results in reduction of the power consumption of the vacuum pump which in-turn decreases the net load on the automotive engine, thus reduces the peak torque, the pump internal chamber pressure and also results better vacuum suction performance.

Abstract: A fuel tank isolation valve 10, wherein, the shaft 18 is assembled coaxially inside hole 42 of moving plunger 46 of seal sub assembly 16 and then flow limiter 22 is guided over the shaft 18 through guiding hole 34 to maintain sealing seat 36 in parallel with respect to the sealing surface 38 of rubber seal 44 and avoid misalignment of flow limiter 22 with respect to sealing surface 38 during and after the operation; the sealing seat 36 of flow limiter 22 on the sealing surface 38 of the rubber seal 44 fixed into moving plunger 46 of seal sub assembly 16 performs the over pressure relief function; the sealing surface 40 of rubber seal 44 fixed into moving plunger 46 of seal sub-assembly 16 is resting on surface 48 of nozzle body 20 to perform over vacuum relief function; and the rubber seal 44 assist both over pressure relief (OPR) and over vacuum relief (OVR) function.

Abstract: A vacuum pump for automobiles used for brake application is provided wherein a method of reducing power consumption and running torque in a vacuum pump of a motor vehicle is explained. The present invention also provides a vacuum pump for automobiles comprising an actuator, a new vane locking assembly, a new vane and rotor assembly, a new non return valve assembly, the controlled oil supply means and a reed stopper assembly that reduces power loss and unnecessary frictional forces and to maintain a controlled oil supply to the vacuum pump.

Abstract: The invention relates to a dual path dual purging system and valve assembly for turbo boosted engines. More specifically, the invention provides an integrated valve assembly connected to facilitate the operation of the low flow valve as a pilot valve for the high flow valve and a system to implement it on turbocharged or supercharged engines. The invention relates to a dual path dual purging system with two purge valves connected to facilitate the use of the low flow valve to be operated as a pilot valve for the high flow valve. This smart routing provides pressure compensation for the high flow valve, when the valve is enabled. This decreases the requirement of force for the high flow valve and gives an option to install a smaller cost efficient solenoid valve.

Abstract: The present invention provides an improved vacuum pump assembly for a motor vehicle comprising of a housing, a rotor, modified vane, a sealing ring, a cover, wherein, the modified vane containing a vane slider is having at least one oil vent or relief hole or slot, for the reduction of the exit port oil peak pressure, by channelizing oil supplies to the vane top and bottom face, thereby improving the seal-ability between the moving and stationary part of the pump; and the modified vane further having an oil vent control at the exit port, for maintaining oil pressure and reducing the exit port hydraulic pressure, leading to reduction in the opposite end vane slider tip load causing low friction between the pump housing, the vane and vane slider, and further channelizing the excess amount of oil to the vane top face which creates additional sealing between the vane and the housing, reducing the air leakage between the low pressure chamber and high pressure chamber inside the pump.
