Single Acting Hydraulic Cylinder Pump
A single acting hydraulic cylinder has only one working chamber, meaning oil can only enter from one port and exit from the other. Therefore, it can only achieve unidirectional movement with the help of a one-way hydraulic control valve. The pump for a single acting hydraulic cylinder is responsible for supplying pressurized oil to this chamber, driving the piston to move in one direction. In the return stroke, the piston is usually pushed back by external forces such as a spring, gravity, or load.
Single acting hydraulic cylinder pumps are widely used in various applications where unidirectional movement is sufficient. These include:
- Construction equipment, such as jacks and lifts.
- Agricultural machinery, like tillers and plows.
- Industrial machinery, such as presses and clamping devices.
- Automotive applications, like car jacks and tire changers.

The working principle of a single acting hydraulic cylinder pump involves the use of fluid pressure to generate force and movement. When the pump is activated, it draws oil from a reservoir and pressurizes it. This pressurized oil is then directed to the working chamber of the single acting hydraulic cylinder, causing the piston to move. In the return stroke, the pressure in the chamber is released, allowing the piston to move back due to the external force.
