Disc springs, also known as Belleville spring washers, are conical discs that can be used individually or in series or in parallel, with axial or dynamic loads acting on the upper and lower outer edges. It is compressed and deformed until it is flattened to store energy as a live load. Automatic conversion to the additional compression load required for sealing, if necessary, to reduce the continued tightening requirements for gaskets and fillers.
