Abstract
A hydropneumatic massage bath includes a bath tub having high side walls and a bottom and at least one pressurized-water line that terminates in a water jet nozzle. An air supply line opens into a chamber surrounding the water jet nozzle. Such chamber has an outlet orifice for a jet of water and pressurized air entering the interior of the bath tub structure is provided for pulsating the jet of water/air mixture that discharges into the interior of the bath tub. To achieve a pleasant and variable massaging effect, as well as to reduce the susceptibility of the system to contaminants and compressive stress, an interrupt mechanism is arranged in the air supply line upstream of the chamber to fully or partially close the air supply at a desired pulsation frequency, thereby controlling the flow of incoming air into the chamber.
