ABSTRACT:
This invention relates to an improvement in plunger valve assemblies for reciprocating sucker rod operated subsurface pumps and specifically as to the traveling valves and standing valves. The traveling valve includes a valve body having an inwardly-directed lip at the bottom with the valve seat, ball and cage inserted from the top of the valve body. Further the standing valve has a closed cage formed in the upper portion thereof which is threaded into the bottom of the pump barrel, thus placing the closed cage of the standing valve and the traveling valve in closer proximity at the bottom of the downstroke than prior such pumps.
