ンプ。[Claims for Utility Model Registration] A pump casing having a housing hole, a plunger slidably housed in the housing hole, and an eccentric that abuts the tip of the plunger and causes the plunger to reciprocate by its rotation. In a plunger pump having a cam, which performs a pumping action by a change in volume of a pump chamber formed between the plunger and the pump casing, the plunger pump is arranged between the eccentric cam and the plunger so that the plunger rotates around its central axis. means for regulating the side wall surface of the plunger from rotating on its own axis; A plunger pump that requires that the excluded portion be provided with a suction port that communicates with the pump chamber.
