EACH HORN PROJECTION (44) IS FORMED WITH AN AIR PASSAGEWAY (446) , WHICH TERMINATES IN FIRST AND SECOND OUTLET OPENINGS (45, 46) THAT ARE ORIENTED IN DIFFERENT DIRECTIONS RELATIVE TO THE CENTRAL SPRAY HOLE (42) . PRESSURIZED AIR THAT FLOWS THROUGH THE NOZZLE (23) EXITS THE SPRAY CAP (4) AT THE MIST FORMING HOLES (43), THE MIST CONTROLLING HOLES (47), AND THE FIRST AND SECOND OUTLET OPENINGS (45, 46) IN THE HORN PROJECTIONS (44).
