ABSTRACT:
A diaphragm for a diaphragm-actuated fluid-transfer control device, which comprises a flexible, substantially non-stretchable diaphragm body of a substantially circular outline surrounded and delimited by a beaded rim, the body having a substantially dish-like, bi-stable shape invertible from the first stable state, in which a first body surface is convex and a second body surface, concave, to the second stable state, in which the first body surface is rendered concave and the second body surface, convex. The device further comprises at least one substantially rigid, elongated arm fixedly embedded in the diaphragm to a depth exceeding the radial width of the beaded rim, the free end of which arm projects beyond the beaded rim. There is also described a diaphragm-actuated fluid transfer control device including the diaphragm.
