An air diffuser for diffusing conditioned air into a room has a diffuser body mounted in a housing to define an air channel which narrows towards the outlet end of the housing to produce a venturi-like effect causing the air to speed up as it leaves the diffuser so that the conditioned air can penetrate stratified layers of air in the room. The diffuser body is of tapered form having a narrow upper end portion and a wider lower end portion disposed in the open, outlet end of the housing. The diffuser body has a surface which faces the internal surface of a sloping side wall of the housing and which is inclined at an angle to the vertical greater than that of the sloping side wall of the housing to provide the narrowing air channel. The diffuser body is adjustably mounted for movement relative to the housing so that the flow of conditioned air leaving the outlet end of the housing can be adjusted.
An air diffuser comprising a housing and a diffuser body mounted within said housing, said housing having a first, inlet end adapted for connection to an air duct, a second, open end forming an outlet for air, and at least one housing wall extending from said inlet end to said second, open end, wherein said diffuser body is mounted within said housing so as to form an air channel between said wall of said housing and said diffuser body which narrows towards said second, open end of the housing, said air diffuser further comprising at least one crane means for adjustably mounting said diffuser body within said housing, said crane means having at least two arms connected by a pivotal joint and a support means fixed relative to said housing, one of said arms being pivotally connected to said support means and another of said arms being pivotally connected to said diffuser body.
