ABSTRACT:
The present invention is drawn to an inlet valve assembly for a subsurface sucker rod operated reciprocating piston pump and, more particularly an inlet valve assembly which is locked in its closed position when the pump is in its unanchored, non-pumping position within the production tube of a deep well. When the subsurface piston pump is anchored within the production tube of the deep well of the inlet valve assembly is freely movable between open and close positions upon reciprocation of the piston.
