Hydro-massage, jacuzzi, whirlpool or spa nozzle unit for the bath jets

摘要

This build-in unit jets a water-air mixt. into the tub from the sides and/or floor. The curved partition section (5) parallel to the bowl-like casing (3) wall (4), forms a suction channel with radial inner- and outer portions. The partition has rotational symmetry about the central axis (A-B) and forms openings (9,10) and a contained flow channel (6). The external drive turns the impeller (11) mounted on the part-hollow shaft (40), inside the channel (6). Atmospheric air enters a radial inlet drilling (23) of the shaft from a tube (26) with a rotating seal (24). A further rotating seal (21) is effected on the water side. The end of the tubular shaft (40) with one of the openings (10), form an annulus (29).
