Abstract: An in-line bubble reducer for inducing turbulent flow in a liquid fluid stream in which gaseous bubbles are entrained. The bubble reducer includes a chamber with an inlet and an outlet, an axial flow diverter for directing the fluid stream outwardly and towards a subsequent annular flow diverter. The annular flow diverter extends from an inner wall of the chamber and induces turbulent flow in the fluid stream to reduce the size of the gaseous bubbles entrained in the fluid stream.

Abstract: A component for hydrotherapy equipment with an overmolded gasket seal to provide a high degree of sealing and compression uniformity to the component housing as well as to the outer shell of the hydrotherapy equipment, the resulting seal reducing gapping between the overmolded gasket and the component as well as the equipment's shell, thus improving water resistance and enhancing the performance of the component and extending the life of the component.

Abstract: Overmolded jets for hydrotherapy equipment components providing enhanced gripping capabilities and ease of manipulation for the occupant of the hydrotherapy equipment in underwater or wet conditions such that the ergonomics of hydrotherapy equipment jets are enhanced and improved.

Abstract: The present invention provides an air control valve for hydrotherapy equipment. The air control valve incrementally controls the supply of air to a venturi jet of the hydrotherapy equipment, thus regulating the flow of air that is mixed with water passing through the venturi jet. Various embodiments of the invention comprise a cammed assembly that translates axial movement of at least one axial member into rotational movement of at least one rotational member, thereby regulating the volume of air flow through a conduit communicating with the air control valve and the venturi jet. Further, various embodiments comprise a push button air control valve that actuates incremental regulation of the air flow volume to the venturi jet.

Abstract: A device for producing a pulsating waterjet having a manifold body with a hollow interior, a fluid inlet, and at least one outlet leading from the hollow interior and fluidly connecting the hollow interior to at least one waterjet; and a selector cam having at least one propelling vane and at least one dam that cooperates with the at least one outlet so as to sequentially align with and unalign with the at least one outlet, wherein the selector cam is rotationally mounted within the hollow interior of the manifold body, whereby fluid entering the manifold body through the fluid inlet impinges upon the at least one propelling vane imparting rotational motion to the selector cam and the at least one dam thereby rotating the at least one dam such that when the at least one dam aligns with the at least one outlet fluid is allowed to exit the manifold body through the at least one outlet and when the at least one dam unaligns with the at least one outlet fluid is thwarted from exiting the manifold body through the

Abstract: A device for producing a fountain comprising a fountain waterjet, at least one inlet, at least one illumination source, at least one outlet, and at least one transparent conduit to permit transference of light from the illumination source to the water stream in order to produce an illuminated fountain, and preferably having an adjustable and removable fountain forming nozzle so as to be able to vary the size and shape of the fountain and to allow access to the interior of the fountain waterjet for cleaning, maintenance and repair.
