ABSTRACT:
A traveling valve assembly is provided for use in subsurface gravity type pumping systems and is responsive to reciprocating motion to manipulate a rotary valve head relative to a valve seat between open and closed positions, and to fluid pressure to manipulate a ball member and a slidable seal member relative to seat members between open and closed positions. Reciprocating motion is converted to rotary motion by means of a journaled spiral groove portion of the rotary valve member. The traveling valve assembly is provided with multiple seals to prevent high pressure gas from blowing through the pump when pumping oil.
