A damper is a kind of cushion that uses oil as a medium to achieve the effect of resisting external forces through the flow of oil in the body of the tube.

There are two types of dampers, passive return dampers, and active return dampers.

The difference between them is that the active return damper has a spring in the bottom of the tube, and the return force of the spring assists the piston rod to return automatically after being compressed.
