Abstract

1,246,604. Valves. JUNKERS & CO. G.m.b.H. 26 Feb., 1970 [27 Feb., 1969], No. 9214/70 Heading F2V. In a water heater water deficiency safety device of the kind in which high and low water pressure is applied to opposite sides of a diaphragm, movement of the diaphragm is communicated to the gas control valve by a stem 15 moulded integrally with a diaphragm plate 14 of plastics material. The plate has a boss 142 and webs 143, and pin 15 which is formed in an undivided part of the mould is slightly conical.
