Patent JP-S58180782-A (JP)
Title: Constant quantity pump
Inventor: KUROSAKI YOSHINORI
IPC: F04B13/00
Filed: 1982-04-16
Abstract: PURPOSE:To prevent occurrence of gas lock by fully closing a check valve with a spring compressed by positive pressure produced in a bore of a casing to prevent a pump from intrusion of bubbles in the intake side piping. CONSTITUTION:A discharge side valve body 15 is lowered to open a valve by positive pressure against repulsion of a spring 16 and forcibly send liquid out of a discharge port 6. Bubbles produced in an intake pipe or near an intake port 4 ascend in the liquid by the buoyancy without intruding into a bore of a casing and are discharged into the atmosphere through a gas vent pipe. Thus, since the bubbles do not intrude into the bore of the casing, gas lock does not take place and normal intake and discharge are continued.
