摘要： An apparatus for use in turning steerable vehicle wheels includes a power steering motor assembly connected with the steerable vehicle wheels. A first pump connected with the power steering motor assembly is continuously driven by an engine of the vehicle, during operation of the engine, to supply fluid under pressure to the power steering motor assembly. A second pump connected with the power steering motor assembly is continuously driven by an engine of the vehicle, during operation of the engine. A valve connected with the power steering motor assembly and the second pump directs fluid flow from the second pump to at least one of the power steering motor assembly and reservoir during operation of both the first pump and the second pump. A pumping mechanism includes a first pumping area defining the first pump and a second pumping area defining the second pump.

摘要： A hydraulically assisted steering system comprises a steering gear operatively connected to a steering wheel and to a set of steerable wheels to effect turning of the steerable wheels in response to rotation of the steering wheel. A hydraulic motor is operatively connected to the set of steerable wheels to assist in turning of the steerable wheels. A pump is fluidly connected to the hydraulic motor to deliver a flow of fluid to the hydraulic motor via a flow path from the hydraulic pump to the hydraulic motor. The flow path from the hydraulic pump to the hydraulic motor is free of any rotary steering control valve. Pressure control apparatus monitors and adjusts hydraulic fluid pressure in the hydraulic motor. The pressure control apparatus adjusts hydraulic fluid pressure in the hydraulic motor by controlling one of pump speed and pump displacement. Direction control apparatus controls direction of hydraulic fluid flow to the hydraulic motor.
