A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy which is then dissipated. Most shock absorbers are a form of dashpot.

Absorber with remote-reservoir connected rigidly, compared to most shock absorbers. It uses a diaphragm instead of a membrane, and does not contain a control valve for expansion of the pneumatic chamber. Description: 1) Sheath and gas tank 2) Stem 3) Snap rings 4) Plate bearing spring 5) Spring 6) End cap and preload adjustment 7) Cap gas, present in versions both with or without gas valve (inverted profile) 8) Mobile diaphragm
In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation.
