プにおけるプランジヤ。 It is formed in two stages with a cylindrical large-diameter plunger part and a rod-shaped small-diameter plunger part, which are fitted into a large-diameter cylinder hole and a small-diameter cylinder hole provided in a cylinder block, and move back and forth. In a plunger pump configured to send liquid at a required pressure to working equipment, the large-diameter plunger portion and the small-diameter plunger portion are separated, and the inner surface of the inward flange of the large-diameter plunger portion and the outer surface of the small-diameter plunger portion are separated. A gap is provided between the large diameter plunger part and the small diameter plunger part, and a seal ring is attached to the inner surface of the inward facing collar to seal the above fitting part, and the large diameter plunger part is fitted with a spring. A plunger in a hydraulic plunger pump, characterized in that the plunger is in pressure contact with a snap spring attached to a small-diameter plunger portion.
