Document Type and Number:
WIPO Patent Application WO/2011/147031
Kind Code:
A4
Abstract:
The present invention provides for an apparatus for use with a traveling valve assembly of a downhole pump for releasing gas and thereby breaking gas locks. The apparatus comprises a piston slidably disposed within a cylindrical housing, the piston being driven by an attached plunger element. On the down stroke of the pump, the piston protrudes through end of the cylindrical housing engaging and opening the adjacent valve. On the up stroke of the pump, the piston retracts into the cylindrical housing, disengaging from the valve allowing it to close. Fluid flows along the outer surface of the apparatus by means of fluid ports connected by defined fluid passages.
