口に連通されてなる往復動ポンプ。 A reciprocating pump comprising a piston means capable of reciprocating sliding in a cylinder body, the cylinder body comprising a cylinder large diameter part and a cylinder small diameter part which can communicate with each other, A piston large diameter part and a piston small diameter part constituting the piston means are slidably installed in the cylinder large diameter part and the cylinder small diameter part in a watertight manner through large diameter and small diameter packing means, respectively. A large-diameter chamber separated from each other and a suction chamber having a suction port are formed by the large-diameter packing means, and these large-diameter chambers and suction chambers communicate with each other via a suction valve, and this large-diameter chamber has a discharge port. A small-diameter chamber is defined in the small-diameter portion of the piston, which communicates with the spillway via a valve and a pressure regulating valve, and is separated from the large-diameter chamber via the small-diameter packing means. A reciprocating pump that is connected to a large diameter chamber, and the small diameter chamber is communicated to a discharge port via a discharge valve.
