Jet propulsion system for spa or jetted bath using control of air draw to venturi jets with a three-way air control valve










Image Number 5 for United States Patent #6968581.

A air selection control valve and assembly capable of controlling the flow of air into a water conduit to accelerate, decelerate, or pulse the rate of water flowing in combination with a hot tub spa assembly is described. The control of the air inlet is controlled to control the pulsing of water. An innovative multi-way control valve system can be controlled by as few as a single solenoid for pulsing some or all of the jets of a standard hot tub spa.
