Abstract
An accumulator system includes an accumulator containing working fluid and gas, an isolation valve through which working fluid selectively flows to and from the accumulator, an actuator operably coupled to the isolation valve, and a passageway fluidly communicating the actuator with gas in the accumulator. The actuator maintains the isolation valve in an open configuration at a first gas pressure to allow working fluid to flow to and from the accumulator. The actuator also allows the isolation valve to close at a second gas pressure less than the first gas pressure.
