Abstract

1486317 Burner controls TI DOMESTIC APPLIANCES Ltd 21 Feb 1975 [4 Oct 1974] 43197/74 Addition to 1410009 Heading F4T [Also in Division G3] A flame failure device for controlling a burner comprises a heat-resistant member 1 to be heated by a flame of the burner so that it expands or contracts along a generally rectilinear axis, member 1 being secured at one end to an adjustable member 3 of a pilot valve, a main valve for supplying fuel to the burner and having an inlet 10, a chamber 17 separated from a valve closure 13 by a diaphragm 12 connected to the closure, and connected to the pilot valve by a line 22, the main valve being arranged to open when the pilot valve is closed due to member 1 being heated, and to close when the pilot valve is open on cooling of member 1. The pilot valve may be in the form of a poppet valve 6, Fig. 1, or may take the form of a ball valve 41, Fig. 3. In operation, gas enters at 10, fills chamber 11 and also passes into chamber 17 through a restrictor 28 and out through a jet 7 with valve 13 closed. If a flame is applied to member 1 the latter expands and closes valve 5, 6, so that pressure builds up in chamber 17 and valve 13 opens to supply fuel to the burner. Any loss of pressure from pipe 22 or from the flame-sensing device will lead to closure of the main valve. In a burner installation Fig. 2, gas is supplied to an oven burner 30 from supply 31 via a tap and thermostat 32, a clock controlled valve 33 and a flame failure valve 34 having a heat sensitive unit 36. Ignition may be by spark or pilot flame.
