ABSTRACT:
A fluid pump with a standing valve above a traveling piston within a housing bore. The traveling piston is mounted on a rod which extends through the housing to a drive mechanism. The traveling piston is constructed so that on the downstroke fluid may pass through a valve in the piston to the bore area above the piston. At the bottom of the downstroke side inlet ports are exposed above the traveling piston to allow more fluid to enter into the bore area above the traveling piston. There is a bottom inlet for fluid to enter during the downstroke of the traveling piston. The upper standing valve raises during the upstroke to unseal outlet ports.
