[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the motion is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The hydraulic cylinder with a hydraulically controlled one-way valve needs to be fixed during production and processing.
