Claims

[Scope of utility model registration request]

A plunger pump that converts rotation of an input shaft into reciprocating motion of a single plunger and generates fluid pressure by the reciprocating motion of the plunger, has a rectangular pump body forming a mounting base, and a pump body guided to the center from the negative side of the pump body. A fitting hole between the suction port and the input shaft enclosure, a single cylinder through hole bored perpendicular to the fitting hole, cylinders accommodated from both ends of the through hole and arranged on the same line; A monolithic plunger having a right circular cross section and a clamping part cut out by a predetermined length on one side of the center for sliding inside the cylinder; a square sliding body attached thereto, and a pump cap configured to hold the input shaft in a position where shaft input can be converted into reciprocating motion of the plunger through the sliding body, and to close the fitting hole. On the other hand, a discharge port or the like is opened on the other side of the pump body, and a communication hole is formed in the pump body through the annular cutout groove of the fitting part of the pump cap and into the through hole in the pump body. A high-pressure conduit through which pressurized fluid flows is a pump consisting of a valve body that is pressed against the cylinder head end via a compression coil spring, a cylinder cap that encloses and holds the coil spring, and a fluid passage within the cylinder cap. A plunger pump characterized by having openings on both end faces of the main body and being connected to each other.
