Disclosed is a piston pump, which comprises: a sleeve housing which has a discharge hole and forms a bore; a piston which has an inflow passage to allow oil to be introduced into the bore in order to be inserted to the bore for reciprocate movement; a suction valve installed to open and close the inflow passage; a discharge valve cover coupled to the sleeve housing to cover a portion in which the inflow hole is formed; and a discharge valve installed to open and close the discharge hole. Moreover, the discharge valve comprises: an opening and closing unit formed to selectively open and close the discharge hole; and an elastic force providing unit which is integrated with the opening and closing unit with an elastically deformable material. Also, the elastic force providing unit is supported by the discharge valve cover so as to have an elastic restoration force.

    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 흡입 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 배출 밸브는 상기 배출 홀을 선택적으로 개폐할 수 있도록 형성되는 개폐부, 그리고 탄성 변형이 가능한 재질로 상기 개폐부와 일체로 형성되며 상기 배출 밸브 커버에 지지되어 탄성 복원력을 갖는 탄성력 제공부를 포함한다.
