摘要： Apparatus for supplying air from a high-pressure air duct to a room, for ventilation of the room. Air from the high-pressure source is passed through a set of nozzles spaced across the cross section of a flow chamber, the apertures of the nozzles being mutually spaced apart by a distance d and the aperture nearest the sidewalls of the chamber being spaced therefrom by substantially d/2. The length of the fluid chamber is at least 3 times d, and a grating is provided across its outlet end. In one embodiment, an adjustably-sized aperture is provided in a sidewall of the chamber near the nozzles to control the quantity of secondary air pulled into the chamber from the room, and hence the velocity of flow into the room. In another embodiment the chamber is a telescoping tube, adjustable to change the chamber length. The apparatus enables a smooth, nearly homogeneous, flow of air into the room, while permitting control of the velocity of air flow into the room, and without materially reacting on the high-pressure source of air.
