Abstract (en)

[origin: EP0595210A1] A diaphragm supporting plate (10) has on its outer edge (20) an axially directed annular groove (30), into which an annular diaphragm (22) is inserted in a distortion-free manner by its clamping bead (28) arranged on the inner edge. By flanging, a flanged edge (32) is formed radially outwards, arranged next to the annular groove (30) on the diaphragm supporting plate (10). The resulting closing of the annular groove (30) causes the diaphragm (22), which consists of a highly flexible material, to be anchored in a pressure-tight and distortion-free manner on the diaphragm supporting plate (10). <IMAGE>
