Claims

[Scope of utility model registration request]

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 inflow path and an outflow path, a cylinder body rotatably fitted to the pintle, and the cylinder body a piston that is slidably fitted into a cylinder hole provided in the radial direction within the housing; and a piston that is disposed eccentrically with respect to the axis of the pintle within the housing and abuts against the tip of the piston to regulate the piston position. The inlet is provided with a guide ring and a drive device for rotating the cylinder body, and the suction and discharge chamber formed inside the piston of the cylinder hole is connected to the inlet and outlet passages of the pintle as the cylinder body rotates. A radial piston pump configured to move over a port and an outflow port, characterized in that the piston is arranged slightly inclined from a direction perpendicular to the axis of the pintle, and the head is formed in a spherical shape. radial piston pump.
