Abstract:
An apparatus comprising:a hydraulic fluid operated automatic transmission for transmitting motive power from an engine of a vehicle to drive wheels of the vehicle; a hydraulic fluid power assisted steering gear for effecting steering movement of steerable wheels of the vehicle, said steering gear including a fluid motor; a body of hydraulic fluid for operating both of said automatic transmission and said steering gear; a reservoir for storing a portion of said hydraulic fluid; a transmission fluid pump connected with said reservoir, a first fluid conduit for conducting hydraulic fluid from said reservoir to said automatic transmission at a relatively low pressure and a second fluid conduit for conducting hydraulic fluid from said automatic transmission to said reservoir; a power steering pump connected with said reservoir, said power steering pump being spaced apart from said transmission fluid pump, a third fluid conduit for conducting hydraulic fluid from said reservoir to said fluid motor at a relatively high pressure and a fourth fluid conduit for conducting hydraulic fluid from said fluid motor to said reservoir; and a cooler for cooling said hydraulic fluid, said transmission fluid pump being operative to pump some hydraulic fluid from said automatic transmission through a fifth conduit to said cooler and from said cooler through a sixth conduit to said reservoir, said power steering pump pumping fluid that flowed through said automatic transmission to said fluid motor.
