ABSTRACT:
A venturi-type mixer that produces an aerated water jet for spas, therapy pools, swimming pools and the like is provided with a pulsating action by means of a rotating flow disturbing blade mounted at the discharge end of the jet nozzle to repetitively intercept the increased velocity stream discharged by the nozzle. The flow disturbing blade has its velocity controlled and adjusted by means of a water-driven turbine rotor journalled upstream of the nozzle and geared to the flow disturbing blade. The amount of projection of the turbine rotor blades into the water stream is varied by changing the relative alignment of non-circular input passage to the jet nozzle with respect to a congruent non-circular input passage from the main water supply.
