Abstract

See full text

A hydraulic system is disclosed for use with a machine. The hydraulic system may have a pump configured to pressurize fluid, a first actuator configured to receive pressurized fluid from the pump, and an accumulator configured to receive fluid from the first actuator. The hydraulic system may also have a second actuator configured to receive pressurized fluid from the pump and the accumulator, and a pilot circuit configured to receive pressurized fluid from the pump and the accumulator. The hydraulic system may further have 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.
