Compression springs are open-coil helical springs that are used to save space and absorb shock in a variety of applications. They absorb the energy of a force acting upon them by becoming shorter, store that energy while compacted, and expand as they release the energy. These springs are either placed over a rod, or fitted inside a hole, and are found in a wide variety of applications ranging from the engine and large stamping presses to appliances and lawn mowers, electronics.
