ABSTRACT:
A gas-lock eliminating traveling valve for a sucker rod operated oil pump includes a fluid outlet ported pump head connecting inner and outer sleeves with the upper end of a working barrel for reciprocating the latter. A valve is tethered within the inner sleeve in a manner insuring separation of the valve from its seat for opening the pump fluid passageway and exhausting gas from the pump bore with each complete sucker rod stroke.
