摘要： A cushioning material sheet to be interposed between a rack support and a press plug for applying an elastic force provided by a spring is formed such that at least its one end face is tapered. Slide-contact surfaces of the rack support and the press plug to be brought into contact with the two end faces of the cushioning material sheet are so formed as to move the cushioning material sheet in a direction perpendicular to a rack support direction, along which the thickness of the cushioning material sheet is decreased. A biasing member is provided to bias the cushioning material sheet in this direction of movement, thereby obtaining a proper meshed condition between a pinion and a rack.

摘要： A pump including a pump chamber 18, formed in a pump body 11, between a cam ring 17 and a rotor 15. The cam ring is formed so as to move in a direction whereby the pump capacity of the pump chamber increases and decreases. First and second fluid pressure chambers 33 and 34 are formed at opposite sides of the cam ring 17. The pump has a spool that is axially moved by a difference in fluid pressure between upper and lower stream sides of a metering throttle 50 connected to a discharge side passage 27 of the pump chamber. The spool is part of a control valve 30 that controls fluid pressure in at least the first fluid pressure chamber. An electronic driving unit, for example, a solenoid 60, applies axial thrust to the spool of the control valve.

摘要： An oil pump includes pump constituent elements, a pump body, and a driving shaft. The pump constituent elements define a pump chamber between a rotor and a cam ring that houses the rotor. The pump body is constituted by a front body and a rear body. The front body defines a housing space for housing the pump constituent elements. The driving shaft extends through and is axially supported by the front body to rotatably drive the rotor. An annular space is formed around the driving shaft in the front body, between a bearing for rotatably driving the driving shaft of the front body, and the pump chamber of the pump constituent elements. A flow control valve is placed in the annular space to return part of a pump discharge fluid from the pump chamber to a pump suction side.

摘要： A device for improving the starting response of a vane pump and for reducing the power loss during a high speed operation of the pump. The vane pump includes a rotor formed with slits, in which slits vanes are slidably disposed. To drive the respective vanes into abutment against a cam ring, a pair of plates which hold the rotor and the cam ring sandwiched therebetween are formed with a plurality of arcuate grooves, into which a discharged oil is introduced. Rather than providing a narrow groove formed in the same plate as that in which the arcuate grooves are formed to provide a communication therebetween, an annular groove is formed in the lateral surface of the rotor to replace the narrow groove or in addition to the narrow groove, and is constructed so that the narrow groove is interrupted by the vanes as the vanes retract, the annular groove providing a communication between the arcuate grooves when a respective vane is driven radially outwardly.

摘要： Hydraulic oil supplied from pumps (12),(13) to an attachment actuator (60) is controlled by attachment control valves (27),(28). Hydraulic oil supplied from pumps (12),(13) to other actuators (52),(54),(56),(58) is controlled by other control valves (21) through (26). Control conditions for operating the attachment actuator (60) alone and control conditions for operating the attachment actuator (60) simultaneously with any of the other actuators (52),(54),(56),(58) are discriminated by the pilot pressure sensors (32),(34),(36),(38). Control characteristics of the attachment control valves (27),(28) are controlled by a controller (43) based on the discriminated control conditions.
