とするラジアルピストンポンプ。 A circular eccentric cam connected to a rotating shaft is rotatably housed in a cam chamber formed in the pump body, and pistons are housed so as to slide freely in cylinders formed radially in the pump body around the cam chamber. A ring with a polygonal cross section equal to the number of pistons slidingly in contact with the base end of the cam is slidably fitted on the outside of the cam, and a suction port is formed at the base end of the piston for sucking the hydraulic oil from the cam chamber into the cylinder. In a radial piston pump in which a notch is formed on the outer circumference of the ring to connect the suction port to the cam chamber according to changes in the relative position between the suction port and the base end of the piston, the center line of the rotating shaft is parallel to the opposite side to the rotational direction of the cam. A radial piston pump characterized in that the center line of the cylinder is set at the moved position.
