往復動ポンプ。 A piston is assembled inside the cylinder so as to be freely movable in the axial direction to form variable chambers at both ends of the cylinder, and a long hole is provided in the axial center of the piston and passes through the cylinder in a state perpendicular to the axis. In the part that passes through the long hole of the rotatably supported input shaft,
An eccentric shaft part is provided which gives a reciprocating motion to the piston by the rotation of the input shaft, check valves are provided in the suction passage and the discharge passage connected to the variable chambers at both ends of the cylinder, respectively, so as to act in a reverse manner, and the cylinder is provided at both ends of the piston. A reciprocating pump equipped with a piston ring that slides elastically into pressure contact with the inner peripheral surface of the pump.
