The present invention relates to a piston pump for a brake system of an automobile. The piston pump comprises: a sleeve housing having a discharge hole and forming a bore; a piston having an inflow passage for introducing oil into the bore and inserted into the bore so as to be reciprocally movable; an inflow valve installed to open and close the inflow passage; a discharge valve cover which is fastened to the sleeve housing to surround a portion where the discharge hole is formed; and a discharge valve installed to open and close the discharge hole. The inflow passage valve includes: a retainer; and an opening/closing member accommodated in the retainer and configured to open/close the inflow passage. The retainer is formed to be elastically deformable to allow the opening/ closing member to move in the longitudinal direction of the piston.

    피스톤 펌프는 배출 홀을 구비하며 보어(bore)를 형성하는 슬리브 하우징(sleeve housing), 오일을 상기 보어로 유입시키기 위한 유입 유로를 구비하며 상기 보어에 왕복 이동 가능하도록 삽입되는 피스톤, 상기 유입 유로를 개폐할 수 있도록 설치되는 유입 밸브, 상기 배출 홀이 형성된 부분을 둘러싸도록 상기 슬리브 하우징에 체결되는 배출 밸브 커버, 그리고 상기 배출 홀을 개폐할 수 있도록 설치되는 배출 밸브를 포함한다. 상기 유입 밸브는 리테이너, 그리고 상기 리테이너에 수용되며 상기 유입 유로를 개폐할 수 있도록 형성되는 개폐 부재를 포함한다. 상기 리테이너는 상기 개폐 부재가 상기 피스톤의 길이 방향으로 이동하는 것을 허용하도록 탄성 변형이 가능하도록 형성된다.
