An overview of the double-acting hydraulic cylinder with cushioning

This paper work presents aspects related with the use of double-acting hydraulic cylinder. In fact, the double-acting cylinder with cushioning is a hydraulic actuator. In the article there are presented two hydraulic circuits and one electro-hydraulic circuit. All circuits are equipped with double-acting cylinder with cushioning. The first hydraulic circuit contains of the following devices: pump unit, tank, 4/3-way hand-lever with spring, throttle valves, double-acting cylinders (Da 1-1). Furthermore, the second pneumatic circuit contains of the following devices: pump unit, 4/3-way hand-lever valve, pressure relief valves, check valves, double-acting cylinders (Da 2-1 and Da 2-2) and 2-way flow control valve. Finally, the electro-hydraulic circuit has the contain of the following devices: pump, tank, 4/2-way solenoid valve with spring, throttle valves, double-acting cylinder (Da 3-1), relays, lamp and valves solenoid.
