AbstractA hydrotherapy system is described in which a movable nozzle with a fluid inlet and outlet pivots about a center point enabling the outlet to be pointed in different directions. A water stream flows toward the passage in the nozzle. The system contains an air inlet and an air outlet passage with a valve chamber communicating between them within the nozzle housing. An air and water check valve moves in the valve chamber to an open or sealed position to allow the passage of air into the chamber but prevents the escape of water.
