An apparatus for the supply of air to a room includes a body (5) fitted with channels designed for the passage of incoming air and outgoing air, and a container (38) for the body, which is designed to hold the body in a position relative to an input duct so that the incoming air from this duct can flow into the first (6) of the channels, and from this channel out into the room, while the incoming flow induces a flow of outgoing air in the second (7) of these channels. The body (5) is movable within a cavity (20) in the container and has its first channel's outlets (8) into the room working in conjunction with the cavity part of the container, so that the body's movement in and out of the container causes the closing or opening of the outlets (8).<IMAGE> |
