Compression springs are coil springs wound with spacing between the coils so that they can be compressed from their free length to a shorter operating length. This allows the spring to store energy and provide a force or pressure. A classic application of the compression spring can be seen in the Road Runner versus Coyote of Looney Tunes fame. Many of the Coyote's gadgets such as the loaded boxing glove, his Pogo shoes and numerous acceleration devices use compression springs as the method of storing and releasing kinetic energy. In fact, any spring based device in the comics is based on the compression springs.
