Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydrauli… Webforced vibrations in the oil volume and damper structure, sticking effects on the valve flaps, valve reactions, and oil foaming and cavitation. See the measurement results for a twin-tube damper in figure 4. The measurements were performed on equipment specially designed for the purpose. The shock absorber was mounted on a 25 kN hydraulic ram
