Abstract
1,196,005. Fluid actuation of switches. ROBERT BOSCH G.m.b.H. 26 Oct., 1967 [27 Oct., 1966], No. 48704/67. Heading H1N. To avoid damage during clamping in manufacture and the need for accurate dimensions, the resilient diaphragm 8 is made less thick than the axial dimension of a locating bore 7, and compressive stresses when fluid under pressure is admitted to chamber 3 via inlet 5 are relied upon to seal the chamber 3 from the contact chamber 17. Before assembly of the switch the diaphragm may be flat or curved (Fig. 4, not shown) and its peripheral surface may be cylindrical or double-conical (Fig. 5, not shown). In a modification (Fig. 6, not shown) the locating bore is conical instead of cylindrical.
