Claims

[Scope of utility model registration request]

(1) The diaphragm defines a pump chamber and a pressure displacement chamber, and the above-mentioned point 7. The pump chamber has a volumetric structure capable of preventing gas retention and increasing the internal flow velocity, and is connected to the suction pipe and the discharge pipe through respective through holes, while a plunger is inserted and disposed in the pressure displacement chamber. In the reciprocating pump, a part of the through hole communicating with the discharge pipe of the pump chamber is branched and connected to a gas vent pipe, and the gas vent pipe is connected to the reciprocating movement of the plunger of the reciprocating pump. A gas vent valve is installed that opens momentarily when fluid is discharged.
Furthermore, the reciprocating pump is characterized in that the gas vent pipe is communicatively connected to a handling liquid supply system via a gas venting portion.

(2) The reciprocating pump according to claim 1, wherein the gas vent valve provided with the gas vent pipe is constituted by a ball valve having a valve seat provided above and below one of the balls.
