Energy management in pump-controlled actuators
Frontiers in Mechanical EngineeringPump-controlled actuators, or more generically, hydrostatic actuators, have the significant advantage of not relying on valves to control the cylinders. This results in much better energy usage compared to traditional valve-controlled systems.
