IMPROVED NOZZLE FOR EMISSION OF A MIXTURE OF WATER AND AIR FOR HYDROMASSAGE, SUITABLE FOR ATTACHMENT TO A WALL OF A TUB Abstract An inner housing (20) is lodged, with possibility of rotation, within an outer housing (10) fixed to an opening (9) in the tub (8); on the housing (20) is fixed an inner duct (21) facing the tub; with the inner housing (20) is united a tubular member (40) communicating with a first chamber (27) and having its own anterior mouth (41) arranged inside of the inner duct (21); to the mouth (41) is applied a one-way valve means (44, 45, 46) capable of closing the passage through the mouth (41) when the pressure in the space anterior to the mouth (41) is greater than [that in] the posterior space; in the duct (21) is placed a tubular obturator (50) having an axial cavity within which is placed the anterior mouth (41) of the tubular member (40) and having an intermediate section (50a) capable, after contact with the outer surface of the intermediate portion (43) of the tubular member (40), of closing off communication between the second chamber (28) and the anterior mouth (22) of the inner duct (21); the obturator (50) is normally held in closure position by elastic means (51) and is capable of undergoing axial displacements due to pressure difference between the spaces upstream and downstream from said intermediate section (50a).
