摘要： A filter to be mounted in a valve seat member for filtering liquid is proposed which can be manufactured without a drawing step, thereby improving productivity and cost performance of a piston pump in which such a filter is mounted. The filter is a flat metal plate including a main body formed with a plurality of filter holes in a central portion thereof, and a plurality of projections integrally and radially outwardly extending from a perimeter of the main body so as to be circumferentially spaced apart from each other. The filter is pushed into a filter mounting hole formed in a valve seat member of a discharge valve in a piston pump with the projections bent toward the opening of the filter mounting hole while being pressed against the inner surface of the filter mounting hole under an elastic restoring force and fixed to the valve seat member.

The piston is configured to slide at an inner wall of the inner bore. The annular sealing member is assembled with the piston so as to slide at the inner wall of the inner bore in the axial direction together with the piston. And a first sliding range of the piston relative to the inner wall of the inner bore and a second sliding range of the annular sealing member relative to the inner wall of the inner bore do not overlap each other in the axial direction.

摘要： A piston pump includes a pump housing having a suction port, a discharge port, and an internal cavity; a first cylinder member having a cylinder bore; a piston built into the cylinder bore of the first cylinder member to thereby form a pump chamber and adapted to change the volume of the pump chamber by means of axially reciprocating movement; a suction valve provided in the piston; and a discharge valve provided at the discharge side of the pump chamber. A circumferential protrusion is formed externally at an axially intermediate portion of the first cylinder member. The first cylinder member is press-fitted, at the circumferential protrusion, into the internal cavity of the pump housing. A leading end portion of the first cylinder member from which the first cylinder member is inserted into the pump housing has a diameter smaller than that of the internal cavity of the pump housing.
