ジアルプランジヤポンプ。[Claims for Utility Model Registration] A cylinder hole formed in a casing, a cap that closes one end of the cylinder hole, and a hydraulic circuit that is slidably housed in the cylinder hole from the other end. The plunger forms a pressure chamber connected to the cap, is biased in the protruding sliding direction by a coil spring interposed between the plunger and the cap, and is slidably operated by an eccentric cam provided in contact with the protruding end. a pin whose head is interposed between the coil spring and the cap and is pressed against the cap side, and whose shaft portion is arranged to be able to guide the expansion and contraction of the coil spring;
A radial plunger pump, characterized in that a bearing is provided between the head of the pin and the cap to support the pin rotatably around the axis without moving the axis.
