ABSTRACT:
An energy storage device particularly suitable for use in hybrid fluid power systems and fluid systems utilizing accumulators. A piston accumulator has a primary face on one end of the piston and a series of secondary faces on the opposite end of the piston. Each face has an associated chamber, and one or more of the chambers of the secondary faces may be selectively connected to a system pressure line. Since the pressure of the system pressure line depends on (and varies with) the number of chambers connected thereto, the potential energy of the chamber of the primary face may be delivered to the system pressure line at a variety of output pressures. Similarly, the chamber of the primary face may be recharged with energy at a variety of input pressures.
