It works primarily like this: mechanical energy from host is transformed into hydraulic pressure energy with the hydraulic pump of the system. As pressure changes, control components like valves and pipes in return transform hydraulic pressure energy into mechanical energy with the help of execute components of hydraulic cylinder and drive up the working structure of the hollow reverse hydraulic cylinder, thus completing rectilinear and reverse motion. As the working media the cylinder, the hydraulic fluid is usually mineral oil, other components like belt, chain and gear works likewise in the mechanical transmission and performance. The hollow reverse hydraulic cylinder is a simple and complete system of hydraulic transmission amid the operation, so it’s good way of knowing its principles by analyzing operation process.
