POWERFUL POSITIVE DISPLACEMENT RECIPROCATING PRESSURIZING DEVICE AND METHOD AND MEANS FOR CONTINUOUSLY VARYING THE PRESSURIZING STROKE

摘要

A powerful positive displacement reciprocating pressurizing device is described for use as a liquid pump or gas compressor capable of generating immense fluid pressures with significant volume flow. A double piston pump is shown driven by a rotating input member with inclined planes operatively interposed between the rotating input member and the pistons. The inclined planes are located as undulations on cam surfaces with peaks and valleys. Antifriction elements driven by the rotating input member roll over the undulations to thereby actuate the pistons in a reciprocating manner. A powerful positive displacement reciprocating apparatus and method for pressurizing fluids with continuously variable strokes at any desired operating speed is disclosed.
