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： 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： 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).

摘要： In a pump housing of a pump apparatus, a pump shaft is rotatably supported by two bearings and is connected to a pump unit. A rotary drive member is fixed to one end of the pump shaft projecting from the tip end portion of the housing. The rotary drive member includes a boss portion fixed to the one end of the pump shaft projecting from the housing, and a rim portion integral with the boss portion. The rim portion is offset from the boss portion to cover at least a portion of the tip end portion of the housing. A groove portion for receiving a drive belt is formed on the outer circumference of the rim portion. The widthwise center plane of the groove portion is located between the respective centers of the two bearings. In place of the groove portion, a tooth portion engageable with a drive gear may be formed on the outer circumference of the rim portion. Preferably, the pump unit is of a balanced vane type.
