Abstract

1336528 Fluid-pressure servomotor systems BARBER-COLMAN CO 25 May 1972 [20 Oct 1971] 24733/72 Heading G3P The flow of air through a duct 1 into a space 2 is controlled by a damper 3 responsive to a flow signal from a detector 5 and to a signal responsive to a condition, such as temperature, within the space from a detector 6. The damper 3 is operated by a bellows 8 supplied with air through a pipe 13 from a duct 1 and connected to atmosphere through a flapper 17 connected to a diaphragm 21 in the flow detector, and through an adjustable linkage 47, 50, to a diaphragm 43 actuated by the detector 6 which may be a bi-metallic element. Air is supplied to the detector 6 and the diaphragm 43 from the pipe 13 through a pressure regulator 33.
