摘要： An axial piston device may be operated as a pump and includes a self-centering rotary valve. The device includes a stationary housing encompassing a shaft and the rotary valve. The rotary valve and the shaft are coupled to each other. Upon rotation, the rotary valve self-centers as a result of elimination of moments and forces within the pump. The inventive pump is a piston device. The valve is within a valve bore, which is a part of a manifold. A shaft is within the manifold and the shaft is attached at its distal end to a planar surface of the rotary valve. The shaft has a first axis of rotation and the rotary valve has a second axis of rotation. During operation of the pump, the first axis is often times offset from the second axis. The pump operates via a swashplate with reciprocating pistons while the housing remains stationary.

摘要： A tilting angle control device 1 includes pressure sensors 51 to 56. Each of the pressure sensors 51 to 56 outputs to a control unit 60 a pressure command signal corresponding to an operation amount. The control unit 60 outputs to an electromagnetic proportional control valve 44 a pressure control signal corresponding to the pressure command signal, and the electromagnetic proportional control valve 44 outputs to a tilt adjustment mechanism 31 pilot pressure p2 corresponding to the pressure control signal. The tilt adjustment mechanism 31 adjusts a tilting angle ± of a variable displacement pump 10L such that the tilting angle ± becomes an angle corresponding to the pilot pressure p2. A pilot pressure sensor 45 detects the pilot pressure p2 to output a pressure feedback signal to the control unit 60. The control unit 60 calculates the pressure control signal based on the pressure feedback signal and the pressure command signal and performs feedback control of the pilot pressure p2.

摘要： A double-headed piston swash plate type compressor includes a rotary shaft, a drive force transmitting member, a tiltable swash plate, a movable body that changes the inclination angle of the swash plate, and a control pressure chamber defined by the movable body and the drive force transmitting member, which are arranged on one side with respect to the swash plate in the axial direction of the rotary shaft. The movable body includes a bottom portion, through which the rotary shaft extends, and a cylindrical portion, which extends from the bottom portion in the axial direction of the rotary shaft to surround the rotary shaft. The cylindrical portion is permitted to move in the axial direction while sliding along a part of the drive force transmitting member, so that the inclination angle of the swash plate is changed in accordance with the internal pressure of the control pressure chamber.

摘要： A compressor includes a swash plate rotated with a drive shaft in a swash plate chamber, a link mechanism that changes an inclination angle of the swash plate, an actuator rotated integrally with the drive shaft, and an actuator control mechanism. The actuator includes a partitioning body fitted to the drive shaft in the swash plate chamber, a movable body that is coupled to the swash plate and moved relative to the partitioning body along the axis of the drive shaft, and a control pressure chamber, the pressure of which moves the movable body. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The swash plate includes a fulcrum point, coupled to the link mechanism, and an action point, coupled to the movable body. The fulcrum point and the action point are located at opposite sides of the drive shaft.
