ABSTRACT:
The travelling check valve of the pump is adapted to be automatically opened at the bottom of the down stroke, so that gasses trapped between the travelling and standing check valves may escape and eliminate gas locking. The valve member of the travelling check valve is provided with a downwardly extending, axial stem. The barrel carries a stationary pin extending transversely across its bore just above the standing check valve. The pump piston, carrying the travelling check valve, brings the stem into contact with the pin as the piston reaches the bottom of its down stroke. This causes the valve member to temporarily unseat until the piston commences the up stroke.
