A disc spring (sometimes called a "Belleville washer" after the inventor) consists primarily of a convex disc supported at the outer periphery by one force and an opposing force on the center of the disc. Disc springs are used singly, or in stacks, to achieve a desired load and travel. The advantage of a disc spring is that it generates high force in a very short spring length and with minimal movement when compressed. All discs are preset so that they will not significantly relax under load over time.
