ABSTRACT:
A diaphragm spring wherein the circumferentially complete outer marginal portion surrounds an annulus of holes constituting the enlarged outer portions of closed slots whose narrower inner portions extend inwardly toward but short of the tips of prongs which surround the central opening of the spring and are separated from one another by radially outwardly extending open slots overlapping the inner portions of the closed slots so as to establish an undulate circumferentially complete annular tension spring radially inwardly of the marginal portion. Each pair of neighboring open slots can flank one or more closed slots. The diaphragm spring can be used in single- or multiple-disc friction clutches.
