Claim:
1. A hydraulic system, comprising: a pump configured to pressurize fluid; a first actuator configured to receive pressurized fluid from the pump; an accumulator configured to receive fluid from the first actuator; a second actuator configured to receive pressurized fluid from the pump and the accumulator; a pilot circuit configured to receive pressurized fluid from the pump and the accumulator; at least one valve movable to provide priority of fluid flow from the accumulator to the pilot circuit over the second actuator when a pressure of the accumulator is less than a low-pressure threshold; and a pressure control valve configured to selectively allow pressurized fluid from the accumulator into the pilot circuit only when a pressure of the pressurized fluid in the accumulator is greater than a pressure of fluid being discharged by the pump.
