A coil spring, also known as a helical spring, is a mechanical device, which is typically used to store energy due to resilience and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. 

Compression coil springs, designed to resist being compressed. A typical use for compression coil springs is in                                                                                               carsuspension systems.
