Abstract:
An air jet for an air massage system for use with a bathtub having a wall defining opposite visible and hidden surfaces, at least one opening being defined through the wall, comprising a hollow body having inlet and outlet ends and unidirectional flow device disposed there between, said outlet end comprising a flange having an annular seat disposed around an inner wall of said hollow body and blades extending radially outwardly from said annular seat, with recesses extending between said blades and outwardly of said annular seat, said blades and said annular seat being adapted to contact the hidden surface, said inlet end being adapted to be in fluid communication with a source of pressurized air, said unidirectional flow device being disposed for allowing air there through only in a direction from said inlet to said outlet end and then through the opening in the wall of the bathtub, thereby preventing water in the bathtub from conveying through said air jet when pressurized air is not fed to said air jet.
