Applications vary from keeping the pressure within a circuit branch to saving load energy. Among these applications, storing and releasing energy has gained attention in recent years due to the need for efficient circuits. In this sense, accumulators are the hydraulic counterparts of batteries and capacitors in electrical circuits.
In many situations, accumulators can be used to store energy during motoring quadrants, i.e., when energy flows from the load into the hydraulic circuit. In one case scenario, accumulators can store energy from several hydraulic actuators and/or motors through a common pressure rail (CPR) system.
In order to address these issues, a hydraulic excavator energy saving system based on a three-chamber accumulator is proposed. Firstly, the conventional piston-type hydraulic accumulator is integrated with the hydraulic cylinder to form a three-chamber accumulator, which has a pressurizing function during energy storage.
