摘要： A power steering system which includes an engine-driven pump, a fluid motor for supplementing manual steering torque, a fluid control valve for distributing fluid to the fluid motor, and a reaction device for applying hydraulic reaction or feeling to a steering wheel. A first flow control valve is utilized to deliver first fluid flow to a fluid control valve from the pump and to lead excess flow to a bypass passage. A second flow control valve is connected between the bypass passage and the reaction device to deliver second fluid flow to the reaction device and to lead excess flow to a reservoir. A magnetic pressure control valve is connected to the reaction device to control fluid pressure applied thereto in accordance with a predetermined vehicle operating condition, such as vehicle speed.

摘要： A vane type hydraulic pump for use in a power steering apparatus comprising a pump housing receiving therein a non-rotatable cam ring and non-rotatable but axially slidable pressure plate and subplate. A pump rotor rotatable integrally with a drive shaft is received in an internal cam bore of the cam ring and, when rotated, delivers pressurized fluid to a discharge port connected to the power steering apparatus. The pressure plate and subplate define at a contact portion therebetween a radial low pressure passage, which is fluidically communicated with an axial low pressure hole receiving fluid from a pump reservoir and bypassed fluid from a flow volume control valve. The radially outer portions of the low pressure passage are gradually curved in a direction of rotation of the pump rotor.

摘要： An electric power steering apparatus (11) includes a reduction mechanism (G) for transmitting the rotation of a rotating shaft (28a) of a motor (28) to a ball screw nut (20) while reducing the speed of the rotation. The reduction mechanism includes a drive gear (29), which is coaxially connected to the rotating shaft of the motor, and a driven gear (16a), which is arranged on the outer surface of the ball screw nut. Due to the reduction mechanism, the motor may be inclined relative to a rack shaft (18).
