ABSTRACT:
A piston-type accumulator in a hydraulic circuit is provided with an interior sleeve proximate the gas valve for limiting piston movement and providing a minimum predetermined accumulator gas volume. By monitoring the pressure of the gas charge in the minimum predetermined gas volume, it may be determined whether the accumulator retains sufficient energy for proper operation in the hydraulic circuit or requires recharging.
