Abstract
PURPOSE:To regulate the air flow rate with good controllability without generation of air frictional sound in a supply and exhaust port device in an air conditioner ventilator by elevationally moving a damper in a casing having an air diffusion plate with a control rod. CONSTITUTION:A supply and exhaust port device 1 is installed at the mounting hole 3 of a ceiling 2, and an essential part consists of a casing 4, an air diffusion plate 5, a damper 6 and a long bolt 7. The air flow rate passing through the gap between the skirt part 10 of the casing 4 and the plate 5 is controlled by elevationally moving the damper 6 via a cylindrical nut 17 upon turning of a rotational part 20 of the bolt 7 to narrow the gap between a short circular tube 16 of the damper 6 and the plate 5. In this case, air which passes through the casing 4 is not leaked via a flexible plate 19, and is collided with the upper portion of the plate 5 to become static pressure. Accordingly, no large frictional sound is generated.
