Abstract:

A temperature sensing assembly which continuously senses the temperature of a constituent stream, of a flow of a gaseous medium and, as a result of such sensing, generates pneumatic servo-pressure to drive air valves, which control the flow of the constituent stream, to open and shut in accordance with specific requirements. The assembly includes a temperature sensing subassembly that senses the temperature of the constituent stream of gaseous flow and that further includes a plurality of adjacent captively-held, bimetallic discs which contract or expand in accordance with preselected ranges of temperatures, and a co-acting spring-loaded ball valve subassembly an air valve subassembly that selectively prevents the flow of a second constituent stream of the gaseous flow, in response to actuation of the temperature sensing subassembly and, a conduit that interconnects the temperature sensing subassembly and the air valve assembly, and that conducts the constituent stream, when flowing, from the latter to the former and then overboard. author
