Abstract
1,259,356. Valves. I.F.R. CROOK. 16 July, 1970 [16 April, 1969], No. 19463/69. Heading F2V. [Also in Division H1] An operating member 1, Fig. 5, for an electric switch or fluid valve comprises a rockable element supported at at least one end by a resilient diaphragm 4 whereby the member has two alternative stable positions. In the example the member 1 is pivoted on a ridge 13 of the base 14 which may be an integrally moulded flexible hinge. In another example the actuator 22, Fig. 9, is mounted on an integral flexible hinge 25 and has a flexible diaphragm 23 at one end only, and which extends peripherally along the rounded end and sides of the actuator 22 so that the diaphragm is of a generally crescent form. A rigid extension 26 of the actuator may extend upwardly above the face of the face plate 24 when the actuator 22 is depressed so that it may be restored to the initial position (shown) by depression of the extension 26. In a modification a rigid actuator 30, Fig. 11, has a downwardly extending web 31 with triangular shaped flexible diaphragm ends 33 integral with fixed ribs 32 whereby two alternative stable positions are also obtained.
