Compression Springs
The compression spring is by far the most common type of coil spring manufactured. They are used as shock absorbers, vibration dampeners, pure energy accumulators, or force generators and are generally fitted over a shaft or positioned between two objects. As the name suggests, compression springs provide resistance as the coils are compressed by an external force, as in a vehicle’s suspension system. When compressed, the coil creates the mechanical energy required to carry a load, hold weight or absorb a force through resistance. Once the external force is removed, the spring will expand, releasing its stored mechanical energy and return to its original position.
