Abstract (en)
A fluid jet nozzle (134,234) for a whirlpool tub or spa including at least one channeling flange (102) defined within and extending from a tapered side wall (140) of a flow passage through the nozzle (134,234) so as to laminarize flow therethrough. Providing such a jet increases whirlpool action adjacent the fluid pumping system or motor of the spa so as to make whirlpool action uniform substantially peripherally of the spa.
