<p>A bathtub for hydromassage, in particular for hydromassaging the back, is described. The bathtub comprises a series of nozzles 12 for delivering liquid under pressure, aligned longitudinally on the backrest 10 thereof in a substantially median position. Said nozzles 12 have associated with them control means for supplying them in succession with the liquid under pressure in one direction or in the opposite direction. This sequence is repeated cyclically for a predetermined period of time. The control means comprise a distributor which receives the liquid under pressure from a supply source and which is provided with a first substantially stationary member 20,34 and a second member substantially movable 24,52 with respect to the first member. The second member is provided with at least one opening 28,56 designed to be positioned, as a result of displacement of the movable member 24,52, opposite openings of the fixed member 22,44 communicating in succession with the series of nozzles 12. In this way the liquid under pressure is allowed to flow into the latter, supplying of the nozzles 12 being performed in one direction or in the opposite direction according to the direction of displacement of said movable member 24,52. <IMAGE> <IMAGE></p> |
