Abstract
A circular duct (10) carrying conditioned air opens into a rectangular outlet diffuser (18). The opening into the diffuser is controlled by a disc (16) which thus acts as a valve to the air flow. The disc is moved by a cranked lever (36, 34) which is fixed to one plate (35) of a bellows. The bellows is opened against the weight of the plate by air admitted from a controller (70). The controller receives air for operating the bellows from a sampling tube (72) in the main duct (10). The controller also receives pressure or temperature signals in accordance with which it regulates the air flow.
