1533137 Fluid-pressure servomotor systems TROX GmbH Gebr 22 Sept 1976 [26 Sept 1975] 39249/76 Heading G3P The gas flow in a conduit 1 of an air-conditioning installation is regulated by a damper 10 in response to changes in the pressure drop across an orifice 2 and temperature changes in a space 13, the latter being sensed by a thermostat 14 to vary the bias 11 on a diaphragm 4 to which the pressure drop is applied. The thermostat 14 controls the pressure in a jack 15. (For Figure see next page)
