Abstract

Air diffuser for rooms and similar spaces, the diffuser being intended for mounting at the end of an air duct ending on the surface of a wall, ceiling or similar structure, and the air diffuser being comprised of an arcuate brace (1) or a similar member with a flow control disc (4) and diffuser body (3) mounted thereon, the flow control disc (4) having an actuator connected thereto for moving the flow control disc (4) between two limit positions called the minimum-opening position and the maximum-opening position, the actuator being equipped with spring elements (7, 11) of which at least one first spring is adapted to serve for moving the flow control disc (4) toward the maximum-opening position while at least one second spring serves for moving the flow control disc toward the minimum-opening position. The invention is implemented so that at least one of said spring elements is a thermally actuated memory metal spring (11) whose spring constant is capable of changing with temperature in a preprogrammed manner.
