Abstract
An air inlet valve having a tubular connector having an open end for admitting air to a room, a cover for regulating the quantity and direction of incoming air, and a tubular guide which telescopically engages the connector and mounts the cover for adjustment toward and away from the open end. The guide has a cylindrical wall extending less than 360.degree. to provide a radial inlet opening between the connector and the cover. The guide is frictionally engaged with the connector by a T-shaped leaf-spring. The spring is held against sideways movement by having its upright slidable in the guide and held against vertical movement by having its cross bar anchored in the connector, whereby the guide may be adjusted both circumferentially and axially relative to the connector.
