ABSTRACT:
A pneumatic control circuit for controlling the discharge of conditioned air from an air distribution system. The circuit is arranged to apply the supply pressure to an inflatable bladder which controls the discharge of conditioned air from a ventilation duct. A diaphragm controls the bleeding of air from the bladder under the influence of the supply pressure, a thermostat, a velocity sensor at the duct outlet and a plurality of selectively sized orifices. The velocity sensor compensates automatically for variations in the main supply pressure so that the control function of the circuit is independent of the supply pressure.
