ポンプ。[Scope of Claim for Utility Model Registration] A piston stroke in which a piston in a fixed cylinder is reciprocated in the radial direction by a rotatably driven eccentric cam, and the suction side port opened at the side of each piston communicates with the suction chamber. In a fixed cylinder type radial piston pump, fluid is sucked in in the piston stroke region, the suction fluid is pressurized in the cylinder chamber in the piston stroke region where the suction side port is closed by a fixed cylinder, and this pressurized fluid is discharged from the discharge port of each piston. , inside a cylinder chamber in which the piston is provided,
A fixed cylinder type radial piston pump characterized by being provided with an accumulator member that expands the volume of the cylinder chamber when the internal pressure of the cylinder chamber exceeds a predetermined pressure.
