カムのカム面に押し付けられかつ他端が回転軸軸
線に直交する方向に配置したシリンダ内を該回転
軸の回転に伴ない往復動するピストンと、このピ
ストンを常時カム面側へ押圧するばねとを備えた
ピストンポンプにおいて、上記ピストンの一端部
に段軸状のフランジを形成し、このフランジの段
部を上記ばねの先端部分が着座するばね座として
構成したことを特徴とするピストンポンプ。 An eccentric cam fixed to a rotating shaft, and a piston that reciprocates as the rotating shaft rotates in a cylinder whose one end is pressed against the cam surface of the eccentric cam and whose other end is arranged in a direction perpendicular to the axis of the rotating shaft. , a piston pump equipped with a spring that constantly presses the piston toward the cam surface side, a stepped shaft-shaped flange is formed at one end of the piston, and the tip of the spring is seated on the stepped portion of the flange. A piston pump characterized by being configured as a seat.
