Abstract: The Invention is a swimming machine operated by a hydraulic pump and hydraulic motor. A first and a second tubular rail support the swimming machine in a swimming pool and are configured to resemble a swimming pool ladder and thus disguise the swimming machine. The configuration of the tubular rails substantially prevents use of the swimming machine as a ladder. A radio-operated remote control proportional relief valve selectably bleeds hydraulic fluid from the high pressure side to the low pressure side of the hydraulic pump, allowing remote control of the velocity of water in the pool.

Abstract: A dual water heating system uses a pump for pumping water from a swimming pool or spa. A filter is coupled to an output of the pump for filtering the water. A water heater heats the water and returns heated water to the swimming pool or spa. A network of non-corrosive piping is disposed within the swimming pool support structure. A plurality of steam ports are coupled to exit points of the network of piping. A steam generator provides steam to the network of piping for transporting the steam to the steam ports and injecting the heated water into the swimming pool or spa. An energy source supplies energy to the steam heater. A motorized or hand-push cart is used to transport the steam heater and energy source. The steam ports are provided along sidewalls or bottom surface of the swimming pool and spa support structure. The steam ports are contained within cavities formed in the support structure.

Abstract: The invention comprises, in one form thereof, a water circulator that connects to the pressurized water inlet in a swimming pool. Water from the pool is pumped through the pool's filter system and into the water circulator through the pool inlet. The water circulator includes a jet tube that is vertically oriented and proximate to the pool's side wall. The pressurized water exits the jet tube through several nozzles in the jet tube. The nozzles direct the pressurized water along the side wall to thereby direct debris toward the pool outlet. The pool outlet carries the debris and water to the pool's filter system. The nozzles direct the water away from the pool outlet so that the water current travels along the majority of the side wall before reaching the pool outlet. Thus, more debris may be picked up in the current and slower moving water passes the pool outlet. The jet tube further includes one or more outlets proximate to the pool floor.

Abstract: A lighting system for use with an above-ground swimming pool includes a water access fixture extending through an aperture in the pool wall, for connection with the pool circulation system; and incorporates a sealed light assembly with a translucent cover; secured in depending adjoined, unitary relation with the access fixture.

A rectifier/transformer 12-volt supply serves the planar array of LED lights, which may be R/G/B and programmed to give a spectrum of coloured lights.

Abstract: A filter housing for a portable spa utilizes a coaxial channel structure at the flow output of the filter housing to separate the water flow from the filter housing. In one embodiment, the water from the filter housing, exiting at the bottom of the housing, is piped by way of a high pressure pump, to the jets in the spa. The water from the filter housing taken at about halfway between the top and bottom of the filter housing is piped, by way of a circulation pump to a heater and a water purifier system back into the spa, preferably to a return aperture in the footwell of the spa. In another embodiment water exiting the filter housing is split into separate flow paths at the bottom of the filter housing, to the jets in the spa and into the circulation loop back into the spa.

Each nozzle is canted to a different angle above the adjacent surface to assist in cleaning sloping parts of the side wall/bottom surface junction and to assist in cleaning any adjacent structures extending from the side wall.

Abstract: A water pump for a spa or the like has a pump water inlet, a pump water outlet and an impeller driving water from said inlet to said outlet. The impeller provides the water axially introduced at the pump water inlet with a radial component which delivers the water to a large plenum chamber surrounding the impeller and which plenum chamber has an increasing cross sectional area as the water moves from the pump water inlet to a plenum chamber outlet thereby reducing backpressure in the water. The plenum chamber terminates with the plenum water outlet located closely to the impeller and a smooth transition area defines the area extending from the plenum chamber outlet to the pump water outlet. The water outlet preferably extends so that the water has a directional component which is generally parallel to the direction of the water entering the pump through the pump water inlet.

Abstract: A recirculating pump system is connected to either skimmers, or a catch basin for a vanishing edge of a swimming pool, to supply water to the suction inlet of the pump system. A water distribution valve operated by an electric control system distributes water from the outlet side of the recirculating pump system to pool cleaning heads normally in accordance with a preprogrammed timed sequence. As part of each programmed cycle of operation of the water distribution valve, water is supplied to one or more pool return jets located on a side opposite the skimmer or catch basin. The return jets create moving surface currents on the water to sweep debris floating on or near the water surface to the skimmer or catch basin. An electric wind speed detector located in the vicinity of the pool and coupled to the electric control system causes the control system to override the programmed sequence in response to wind exceeding a pre-established threshold to operate the pump system to supply water to the pool return jets.

Abstract: A fitting, in the form of a mounting collar for installation of a water input nozzle, such as a cleaning head in the floor and walls of a swimming pool, is designed to permit the fitting to be rocked from side to side a limited amount relative to the central axis of a water supply pipe in which the fitting is inserted during initial installation. This is done to allow for installation discrepancies where the water supply pipe is not perpendicular to the surface of the pool where the pipe opens into the pool. By allowing this amount of movement in the installation of the mounting collar, the orientation of a pop-up cleaning head, for example, with respect to the pool floor or wall, is ensured to be perpendicular; so that optimum cleaning of the pool surface during subsequent use of the system occurs.

Abstract: The system includes a jet, a rotating member or "eyeball" and a diverter cap formed with a number of bore holes positioned at a common radius from the center of the cap. The jet produces a high pressure water jet that flows through the eyeball causing it to rotate at a high speed and discharge the jet in a circular pattern that impinges on the bore holes. The bore holes are formed in the diverter cap so that the upstream intersection of the bore holes forms a series of ridges that divert the rotating jet into the appropriate bore hole(s) without blocking the jet and producing a back flow and are aligned with the rotating eyeball to minimize pressure losses experienced by the jet. Together the rotation speed and bore hole design produce the sensation of a number of simultaneously pulsating water jets that are directed into the spa or tub. The system has the added advantage in that its design results in low pressure losses.
