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 hydraulicfluid from the front to the back (or visa versa) of that reservoir. When animpulse load occurs and the piston tries to move at a high speed, a valve willclose thereby restricting or blocking the movement of the fluid within thereservoir and subsequently locking the moving piston.
