Abstract

A hydraulic system may include a hydraulic actuator. The hydraulic system may also include a pump having a pump inlet and a pump outlet, and the pump may be configured to supply fluid to the hydraulic actuator. The hydraulic system may further include an energy recovery system operatively connected between the hydraulic actuator and the pump. The energy recovery system may be configured to store fluid from the hydraulic actuator under an overrunning load condition, and the stored fluid may be directed through the pump inlet and into the hydraulic actuator.
