Abstract
A hydrotherapy spa having a water jet into which air is aspirated through a conduit and a control valve for varying the effective flow area to the conduit from space inside the spa. The control valve comprises two generally cylindrical valve body members fitted together and defining an inlet passage extending outwardly between the two, and an outlet passage extending inwardly through the inner member and containing a ball check valve for preventing a reverse fluid flow. A cup-shaped cap is snap-fitted on the outer end portion of the valve body and formed with a closure member on its underside for variably opening arcuate ports in the outer end of the body variably connecting the inlet and outlet passages through these ports.
