ABSTRACT:
A oil well reciprocating piston pump is fluid pressure operated from a source at the earth's surface. The piston is hollow and serves also as a sealed cylinder for a free piston which is gas biased downwardly. The underside of the free piston is in contact with a body of oil displaceable from the sealed cylinder into the annular space between the hollow piston and its cylinder to bias the hollow piston toward the bottom of its stroke.
