Claim 1
Independent Claim
208 words
A Ceiling air terminal comprising: a primary chamber adapted for connection to a source of conditioned air; opposed, downwardly projecting wall members having outwardly flared end portions thereon associated with said primary chamber, said wall members forming a passageway therebetween for discharging conditioned air from the terminal; opposed cutoff means disposed within said passageway; a triangularly shaped diffuser member adapted for cooperation with the outwardly flared end portions of said wall members to provide a substantially horizontal discharge of conditioned air from the terminal; damper means including opposed plate members, inflatable bladders mounted on said plate members for cooperation with said cutoff means to restrict flow of air therebetween when said bladders are inflated; a control module comprising a frame member; a pressure regulator adapted to receive air from said primary chamber and regulate the pressure of control air supplied to said bladders, said regulator being mounted on said frame member, said damper means and said control module being mounted on said triangularly shaped diffuser member to form a damper control module assembly therewith; guide means mounted on said terminal for slidably receiving and centrally locating said damper-control module assembly between said side wall members; and clip means for releasably securing said damper-control module assembly in said terminal.

Claim 3
Dependent Claim
65 words
A ceiling air terminal according to claim 1 further including filter means mounted in said frame member between said pressure regulator and said primary chamber to filter the air supplied to said regulator, a thermostat mounted in said frame member, said thermostat being adapted to receive said air from said regulator for cooperation with said regulator to control the degree of inflation of said bladders.
