Abstract
A hydrotherapeutic jet for a hydrotherapeutic receptacle employs three nozzels and two separate mixing chambers. A primary stream of water flows through the first nozzel to create a low pressure condition which sucks air into the first mixing chamber, causing the primary stream to be mixed with the air. The primary stream is discharged through the second nozzle into the second mixing chamber, thereby creating another low pressure condition which sucks a secondary stream of water from the hydrotherapeutic receptacle into the second mixing chamber and hence causes the aerated primary stream to be entrained with the secondary stream. The air/water mixture is then discharged from the second mixing chamber into the hydrotherapeutic receptacle by te third nozzle.
