The compression spring is wound with wires of various materials, the ends are flat, and there is a certain gap between the ring and the ring, which is mostly represented by a circular cross section. When subjected to an external load, the spring shrinks and deforms, and the deformation energy can be stored. The compression spring has the widest use, the simple shape and the highest variability in the spring, making it the most widely used of all spring types.
Applications: push button springs, hydraulic springs, valve springs, valve springs, oil seal springs, battery springs
