In bringing a moving load to a stop, the EGD shock absorber converts work and kinetic energy into heat which is dissipated to the surroundings. EGD shock absorbers are filled completely with oil, therefore, they can be mounted in any position or angle. The spring return units are entirely self-contained, extremely compact that require no external hoses, valves, or fittings.
The shock absorbers are multiple orifice hydraulic devices. The orifices may be fixed or adjustable. When a moving load strikes the bumper it sets the rod and piston in motion. The moving piston pushes oil through a series of holes from an inner high pressure chamber to an outer low pressure chamber.
The resistance to the oil flow caused by the holes creates a pressure that acts against the piston to oppose the moving load. At the end of stroke the load comes to a gentle rest and the pressure drops to zero gage pressure. This results in uniform deceleration and gentle stopping with no bounce back.
