板式可変容量形ピストンポンプ。 A rotating body that is rotationally driven by a drive source with a variable rotation speed, a plurality of pistons that are installed on the rotating body to be able to slide back and forth so that liquid can be sucked and discharged by the rotation of the rotating body, and the inside of the pump body can be tilted freely. and a swash plate connected to the piston so as to change the amount of reciprocating sliding of the piston provided on the rotating body by changing the inclination angle and thereby change the amount of liquid discharged. The inclination angle can be changed freely by the opposing action of the pressing force, and the centrifugal force generated by the rotational drive of the rotating body is applied to the swash plate so that the inclination angle of the swash plate can be changed according to the fluctuation of the rotational speed of the rotating body. A swash plate type variable displacement piston pump that has a conversion mechanism between the rotating body and the swash plate.
