<p>A venturi jet unit (70) for whirlpool bath assemblies has a main body (72) with a water inlet bore (80), a water outlet bore (86) and a venturi throat (85) of restricted cross-sectional area between the water inlet bore (80) and the water outlet bore (86). An air duct (88) communicates with the water outlet bore (86) immediately downstream of the venturi throat (85). A ball-type outlet jet (73) is mounted in the water outlet bore (86) to receive water from the venturi throat (85) and co-operates with an outlet (91) of the air duct (88) to control air entering the jet (73) for mixing with water in the jet (73) prior to discharge into a bath on which the unit (70) is mounted. Thus, a number of units (70) are mounted around a bath side wall in use and the air entering each unit (70) can be independently controlled for each unit (70). The unit (70) is also self-draining. <IMAGE></p> |
