ABSTRACT:
A gas piston driven hydraulic piston pump in which the gas cycle is of high efficiency by injecting the gas in slugs at the beginning of each power stroke. The hydraulic piston (40) is disposed to operate inside the gas piston (30), and the two pistons, both slidably but non-rotatably mounted, are coupled together with a rotating but non-sliding motion transfer ring (50) extending into antifriction grooves (46 and 37) in the sidewalls (42 and 32) of the two pistons. To make the hydraulic piston move at a constant speed during constant hydraulic horsepower demand and thus exert a constant pressure on the hydraulic fluid, these grooves are machined with variable pitches and one is the opposite of the other, i.e., the gas piston groove (37) increases in pitch during its power stroke while the hydraulic piston groove (46) decreases. Thus the motion transfer ring (50) is properly denominated a force multiplier ring. Any number of piston assembly sets may be used to obtain desired hydraulic horsepower.
