Abstract

See full text

A hydrotherapy jet assembly and/or installation configured to discharge a high intensity stream into a water tub without requiring air entrainment. Passageway means are provided for drawing water from the tub into the mixing chamber of a jet assembly for entrainment by a water jet. The stream discharged from the jet assembly into the tub is comprised of (1) water supplied under pressure into the mixing chamber by a water jet nozzle and (2) water drawn from the tub for entrainment by the water jet. The effect of tub water entrainment is to produce a high intensity stream for impacting against a user's body without significantly lowering the temperature of the water pool in the tub.
