Abstract

940,637. Temperature-responsive actuating - elements. COCHRAN & CO. ANNAN Ltd. Sept. 10,1962 [June 12,1961], No. 21172/61. Heading G1D. [Also in Divisions F2 and F4] A temperature responsive device 8 which regulates the flow of fuel to a burner by means of a valve 7 in proportion to the air flow thereto projects into the air stream and comprises an inner rod 13 of alloy steel or other material of low coefficient of thermal expansion housed within and attached at one end to a tube 10 of steel or other material of high coefficient of expansion. An electrical heating element 14 is arranged to heat that portion of the tube which projects into and is therefore simultaneously cooled by the air stream, a rheostat 15 being provided to allow for preselection of the rate of heating of the tube 10. The tube 10 is attached at its other end to the valve 7 while the inner rod carries a frusto-conical valve member 21 which controls the flow of fuel through the valve 7 from inlet port 26 to outlet port 27. The valve member 21 is screwed into the rod and may therefore be adjusted in its initial setting. Variations in the rate of air flow produce variations in the rate of heat extraction from the device and therefore also in its temperature; variations in the temperature of the device are reflected in adjustment of the setting of the valve member 21 due to the differential expansion of the rod and tube. To compensate for variations occurring in the air temperature without alteration in its flow rate part 17 of the rod 13 may be constructed of material of high coefficient of thermal expansion. In a modification, (Fig. 4 not shown) the end of the inner rod is formed as a needle valve. The tube 10 may be heated by passing a current through two dissimilar metals one of the junctions of which lies close to the tube 10 i.e. employing the Peltier effect, or by the circulation of a heating medium through the device. In instances in which the combustion air is preheated a cooling medium e.g. water may be circulated at constant rate through the device extracting heat from it.
