ABSTRACT:
The invention relates to a nozzle head, especially for use in a de-icing device for aircraft, to emit a liquid in the form of a spray. The nozzle head comprises a supply chamber for the liquid, a nozzle ring member, and a central member which is provided in the latter and is movable by the aid of a set means for adjustment of the spray in the nozzle axis, and which in one end position will close the connection between the nozzle annulus formed by the nozzle ring member, and the central member and the supply chamber. The nozzle head is characterized by the fact that the central member constitutes the nozzle ring member of a concentric inner nozzle with a central pin which is operatively connected with said set means and is connected with the central member by a free play spring, so that the central pin is not displaced until said central member is in its mentioned end position in which position the inner nozzle is at the same time put in liquid flow connection with the supply chamber of the nozzle head.
