Abstract:
A spa with a slide valve controlling the admission of air to an air and water mixer in the spa. The slide valve has a closure element slidably mounted within a cylindrical valve chamber of a valve housing, and an air admission slot in the valve housing. Movement of the closure element changes the extent of the slot which communicates with an end of the valve chamber and through this end with a water and air mixer.
