Abstract
Official abstract text for this publication.
A reciprocating pump includes: a housing with a fluid channel that includes a pump chamber; a reciprocated member that is disposed in the housing to form the pump chamber, and reciprocable for suction and discharge of fluid; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the fluid channel via the pressure receiving portion. The housing includes an inner wall facing the fluid channel, and a flexible, membranous portion placed continuously next to the inner wall to face the fluid channel. The pressure gauge is attached to the housing such that the membranous portion is sandwiched between the pressure receiving portion and the fluid channel.
First claim
Opening claim text (preview).
What is claimed is: 1. A reciprocating pump for transferring fluid, comprising: a housing with a fluid channel that includes a suction port, a discharge port, and a pump chamber communicating with the ports; a reciprocated member that is disposed in the housing to form the pump chamber in a reciprocable manner such that the fluid is sucked into the pump chamber through the suction port and discharged from the pump chamber through the discharge port; an actuator configured to reciprocate the reciprocated member; and a pressure gauge with a pressure receiving portion, configured to detect pressure of the fluid in the fluid channel via the pressure receiving portion, wherein the housing includes: an inner wall facing the fluid channel; and a membranous portion made of a same kind of material as the inner wall, integrally formed with the inner wall, having flexibility due to having a thickness smaller than a thickness of the inner wall, placed continuously next to the inner wall to face the fluid channel, and including an inner surface that faces the pump chamber and that is coplanar with an inner surface of the inner wall that faces the pump chamber, and the pressure gauge is attached to the housing such that the membranous portion is sandwiched between the pressure receiving portion and the fluid channel. 2. The reciprocating pump according to claim 1 , wherein the reciprocated member comprises a rolling diaphragm. 3. The reciprocating pump according to claim 1 , wherein the reciprocated member comprises a bellows.
