    Patent number: 4043122
    Abstract: Apparatus for imparting reciprocating motion to a double-acting hydraulic piston and cylinder motor assembly. Hydraulic fluid is supplied through pressure lines alternately to opposite ends of the cylinder by two pumps. The pumps are operated so that one is on its pressure stroke while the other is on its suction stroke. The valving is such that fluid flowing out of the cylinder is discharged to an unpressured reservoir and fluid flowing into the pumps on their suction strokes is drawn from the same reservoir.
