Abstract
A plurality of water injection nozzles (16) are spaced around the tub (12) of a hydrotherapy spa (10) for injecting a pulsating flow of water and air into the main body of water (14) in the tub (12). The pulsation is produced by a distribution valve (30), (80) including a rotor (46), (92) which is rotated by the inlet water flow and distributes the inlet water to outlets (40,42,44), (90) which are connected to the nozzles (16) respectively. The rotor (46), (92) is formed with a groove (48), (96) which sequentially aligns with and connects the outlets (40,42,44), (90) to the inlet (34), (86). Since each outlet (40,42,44), (90) is periodically connected to and disconnected from the inlet (34), (86), the water is supplied to each nozzle (16) in a pulsating or chopped manner. The sequence in which the water is distributed to the nozzles (16) is fixed, enabling a rippling effect to be produced in which the pulsation appears to rotate around the spa (10).
