How does a hydraulic snubber work?

The basic working principal behind a hydraulic snubber is that under slow (normal) speeds, a piston moves within a hydraulic reservoir pushing hydraulic fluid from the front to the back (or visa versa) of that reservoir. When an impulse load occurs and the piston tries to move at a high speed, a valve will close thereby restricting or blocking the movement of the fluid within the reservoir and subsequently locking the moving piston.
