Abstract
A unitary apparatus combines the pneumatic switch and air control functions of separate conventional devices thereby eliminating the requirement to put two separate devices in a jetted whirlpool bath or spa. Two embodiments of the invention are disclosed herein. In each such embodiment, in addition to the pneumatic pump there is an air control body joined to a threaded body, the latter housing an air outlet and a push tube positioned concentrically within a rotatable face member. The push tube provides a button the depression of which activates the air pump using a pneumatic pulse. The face provides a means for controlling the whirlpool action generated at the output of a plurality of Venturi jets attached to the system. The face is substantially resistant to removal which would expose an easily removable plunger tube, tapered ring and other small members of the invention. This latter feature makes it necessary to fully depress the push tube before it becomes possible to disassemble the face from the remainder of the apparatus. In one embodiment the air pump is configured to permit its replacement from the interior of the tub without requiring access to the tub exterior.
