    Nov 11, 2017 · A new hydraulic hybrid excavator potential energy recovery system is proposed in this paper. The energy recovery system uses threechamber cylinders (TCCs) and accumulators to recover potential energy during work cycle. Within this structure, there is no throttle valve in the primary loop, and the recovered energy is stored in the form of hydraulic energy. Hence, energy loss of throttle valve
