ABSTRACT:
A vibration-free hydraulic power system having an opposing pair of pistons adapted to be moved in unison with the same stroke and equal force, but in opposite directions, one of the pistons being operatively connected to an external mass to be moved, the other of the pistons being operatively connected to a reactive mass the weight of which is identical to the weight of the mass being moved, the reactive mass acting to maintain the system in an equilibrium state during its complete operating cycle, the system incorporating a pair of control valves each having a series of sequentially acting valve elements which control fluid flow to and from the system, the pistons and control valves working at all times against solid columns of fluid under positive but variable pressure.
