Abstract

886,245. Thermally actuated valves. DRAYTON REGULATOR & INSTRUMENT CO. Ltd., and BROWN, G. F. Nov. 4, 1958[ Nov. 15, 1957], No. 35683/57. Class 135. [Also in Groups XI and XIII] For a boiler supplying hot water for space heating, a draught-control apparatus of the kind e.g. as described in Specification 798,099 in which a pilot bulb 14 of expansible liquid is supported in a bush 15a in the boiler wall to extend into the water space and communicates by a tube 13 with a bellows 9 which controls a damper 3, has a further bulb 33 also connected by a tube 32, to the bellows and mounted on an outside wall of the building. The bellows, as in the prior Specification, moves the damper by way of a rod 8 and a lever 1 pivoted by a pin 22 on a further pivoted lever 18. Any contraction of the liquid in the bulbs 14, 33, due to cooling opens the damper 3 to increase the heating of the boiler.
