特徴とするラジアルピストンポンプ。 An eccentric cam connected to a rotating shaft is rotatably housed inside a suction recess formed in the pump body, and a piston that comes into contact with the eccentric cam is disposed to freely slide radially inside the pump body, and suction is generated by expansion and contraction of the piston. In a radial piston pump, an oil chamber that sucks and pressurizes hydraulic oil in a recess is formed in the pump body facing each piston, and a front cover that seals the suction recess is fixed to the side of the pump body. A discharge passage for collecting hydraulic oil is formed by casting inside the pump body, and each oil chamber and this discharge passage communicate with each other through holes opened on the side of the pump body, and the openings of these holes are connected to one part of the front cover. A radial piston pump characterized by a blockage in the radial piston pump.
