Physics:Hydrospring
A hydrospring or hydro-spring is a spring damped by hydraulic fluid (typically oil) being driven through holes in a piston, as the piston moves in response to a force. The spring is often made of rubber. Inside a rubber hydrospring there are hydraulic viscous damping systems which damp movement in all three directions but require very few parts. Even the slack adjustment may be integrated into the element.[1] Hydrosprings are used mainly as shock absorbers in applications such as damped suspension in railway bogies, bulldozer blade shock absorbers and as recoil absorbers for artillery.
