Abstract: A rack and pinion power steering system 10 is provided and includes a variable orifice valve 22 which controls the flow of fluid in and out of a hydraulic cylinder 20. Variable orifice valve 22 is communicatively coupled to a source of pressurized fluid 30 by use of a conduit 42 and an electronically controlled valve assembly 38. The pressurized fluid received through conduit 42 controls the operation of valve 22. Based upon the pressure of the received fluid, valve 22 selectively increases and decreases the volume of fluid flow in and out of cylinder 20, thereby causing cylinder 20 to have enhanced damping characteristics during certain vehicle operating conditions (e.g., during relatively high vehicle speed operating conditions).

Assembly 108 is created by forming a first member 10 and a second member 40, by placing pinion support members 80 within the second member 40, by placing gear assemblies or pinions 63 upon each of the pinion support members 80, and by coupling the pinion support members 80 to the first member 10, thereby forming gear assembly 108.

Abstract: A system 10 which utilizes engine coolant to selectively heat and cool fluid or oil used by another vehicle system, such as a transmission 14. System 10 includes a first cooling path or circuit 28 having a fluid-to-fluid heat exchanger 18 which is fluidly coupled to engine 12. The system 10 further includes a second fluid flow circuit 36, which contains and communicates transmission oil or fluid to and from transmission 14. Circuit 36 includes a conventional solenoid controlled shunt valve 22 which is fluidly coupled to transmission 14 and to fluid-to-fluid heat exchanger 18. Valve 22 is effective to selectively channel transmission oil through heat exchanger 18 based on one or more parameters (e.g., ambient temperature and transmission oil temperature), thereby relatively rapidly heating the transmission oil under certain operating conditions.

Abstract: An exhaust manifold 10 having a body 12 and a plurality of flanges 14-24. The body 12 is separately fabricated apart from flanges 14-24. The flanges 14-24 are later joined to the body and cooperatively form an exhaust manifold 10.

Abstract: A battery cooling system 10 for use with a vehicle 14 including several batteries or battery modules 16-38 which provide power to the vehicle 12. The system 10 includes a refrigerant gas channeling or conduit system which is effective to store, compress, expand and circulate refrigerant gas through the battery pack 12 and the system 10. A first “high pressure” conduit system, having several tubes or conduits that are disposed throughout the vehicle 14, is used to selectively carry and transport pressurized or compressed refrigerant gas to the battery pack 12 and includes a pump 42, a heat exchanger 44, expansion valves 46-52, and conduits 54, 56, 58, 60 and 62. A second “low pressure” conduit system is used to circulate the “expanded” or decompressed refrigerant gas throughout the battery pack 12 and to return the refrigerant gas to pump 42 for recompression.

The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression head cap further includes a plurality of members which are selectively and movably disposed within the contained environment and which selectively remove an amount of the material from the environment, effective to prevent the material from being undesirably dispensed by the head cap.

Abstract: A system 10 for electrostatically painting a product or vehicle 12. The system 10 ensures that each product or vehicle 12 which is painted is sufficiently and completely grounded prior to being painted, thereby substantially preventing the products or vehicles 12 from being improperly painted and improving the overall efficiency of the painting process.

Pattern 10 may also include several validation pads or points 50 which allow the produced crankshafts to be measured with improved accuracy.
