The cylinder is hydraulically controlled only in one direction, that of output. It is schematized accordingly. Function of single acting hydraulic cylinder. The output of the single-acting cylinder is controlled by introducing oil under pressure. The inlet of the cylinder is made when ordering the return of the oil to the tank. The pressure drops in the chamber and the spring or the simple weight of the load pushes the piston. Some raw materials are listed in the Chemical Spectra Database.
The input and output movements are hydraulically controlled. The active outlet section of the cylinder is the total surface of the piston. When entering, it is the section of the piston that surrounds the rod since the oil can not act on the section of the rod. So when filling a room, the other is empty. As a result, the output and input speeds are different.
