Abstract

The invention relates to a diaphragm spring of the type having a resilient annular part 2 and, projecting therefrom and being integral therewith, radially extending tongue- shaped projections 3. The latter are unaffected by the resilient deflection of the diaphragm while the annular part changes its curvature during such deflection. To reduce the danger of premature failure in the transition zones 6 between the annular part 2 and the projections 3 and the effects on the spring characteristic of the diaphragm, openings 7 are provided in the transition zones 6. One or more openings can be provided in each zone and the location of the openings may be determined by the requirements of the spring characteristic. The projections may extend outwardly rather than inwardly from the annular part. The openings may extend into the projections. The spring may be planar or conical in its free state. <IMAGE>
