Water delivery head for whirlpool baths

摘要

Water delivery head for whirlpool bath-tubs and the like, comprising a manifold body (4) with a pressurized-water inlet orifice (5) communicating with a nozzle (7) through adjustment means for the water passage cross-section and a hollow body (8) which is integral with the nozzle and capable of being swiveled with respect to the manifold body. The latter further comprises two air intake orifices (6) communicating with the lead-in opening (9) of the nozzle so as to generate an air-water mixture being ejected from the same nozzle. The hollow body (8) has a semispherical surface that cooperates frontally in a sliding manner with an external annular rib (13) that is fixed to the manifold body (4). Said hollow body (8) is coupled on its rear side with a flexible discoidal wall (14) having a flared central passage (24) pivoting on a central pin (26) that is fixed at the rear to the manifold body (4) and is provided with an axial hole (28) through which the air intake orifice (6) communicates with the nozzle (7). The nozzle (7) can be swiveled conveniently, with no appreciable friction problem.
