hydraulic spring
Quick Summary
A spring is an elastic machine component that deforms under load and returns to its original shape when the load is removed. This stored energy can be used to arrest loads or as a power source. While most springs are mechanical, hydraulic and air springs also exist.
Hydraulic springs are cylinders where fluid compression and cylinder wall deformation create the spring effect. They are useful for high-load applications. Air springs use confined air in a bellows-like container, maintaining a constant vehicle height regardless of load. Common mechanical springs include helical, leaf, and spiral springs, each with various applications from vehicle suspension to clocks.1
