Claims

[Claims for Utility Model Registration] (1) A casing having a suction port and a discharge port, a housing fixed to the casing, a pintle fixed to the housing and having an inlet passage and an outlet passage, and a pintle rotatable to the pintle. A cylinder body to be fitted, a piston to be slidably fitted to a cylinder hole provided in the radial direction in the cylinder body, and a piston disposed eccentrically with respect to the axis of the pintle in the housing, and a piston tip end. a piston guide ring that abuts against the piston to regulate the piston position; and a drive device that rotates the cylinder body, and the suction and discharge chamber formed inside the piston of the cylinder hole rotates as the cylinder body rotates. In a radial piston pump configured to move on an inflow port and an outflow port connected to an inflow path and an outflow path of a pintle, the inflow path is formed from one axial end of the pintle, and the outflow path is formed from the other end. A radial piston pump characterized by: (2) The radial piston pump according to claim (1), wherein the inflow port and the outflow port are formed apart from each other in the axial direction of the pintle.
