An ozone generator for providing ozone enriched air that comprises a body for defining a chamber for air flow therethrough and an ultraviolet lamp disposed in said chamber for irradiating the air passing through said chamber to convert oxygen molecules to ozone molecules. The device further comprises an air inlet for introducing air and a diffuser for diffusing the introduced air about said lamp. The diffuser has an annular flange with a plurality of apertures therein, said annular flange extending inwardly from a cylindrical portion encircling the annular flange, the cylindrical portion abutting and extending from the annular wall. The device further comprises an air outlet for discharging ozone enriched air.

A method for cleaning a pool surface is carried out by structure having a protruding nozzle assembly mounted in a side wall of a swimming pool in communication with a source of water for ejecting through a nozzle of a nozzle housing a stream of water at a predetermined angle relative to the adjacent side wall surface. During each erection and retraction of the nozzle housing precipitated by initiation and cessation of water flow to the nozzle assembly, the nozzle housing rotates incrementally to provide a plurality of streams of water defining a fan-like area from each nozzle as such nozzle comes into fluid communication with an opening in a cover enclosing the nozzle housing. Each nozzle is canted to a different angle above the adjacent pool 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.

Method for cleaning pool surface

A protruding nozzle assembly, mounted in a side wall of a swimming pool in communication with a source of water, will eject through a nozzle of a nozzle housing a stream of water at a predetermined angle relative to the adjacent side wall surface. During each erection and retraction of the nozzle housing precipitated by initiation and cessation of water flow to the nozzle assembly, the nozzle housing will rotate incrementally to provide a plurality of streams of water defining a fan-like area from each nozzle as such nozzle comes into fluid communication with an opening in a cover enclosing the nozzle housing. 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.

Lower region of a cylindrical nozzle stem is longitudinally slotted to provide flexible tines and the tines have outwardly projecting lands at their distal ends. The flexibility of the tines permits the nozzle stem to be force filled into and through a ribbed region of a surrounding retainer. Further, the flexible tines permit a cylindrical metal weight, and a weight cover to be slipped over the lower end of the nozzle stem to be held in place by the lands on the tines. No separate fasteners nor adhesives are required to hold the assembly together.

Apparatus for cleaning swimming pools

Alignment arrangement between a valve module and a base containing outlet chambers assures that the valves in the valve module are correctly positioned relative to the chambers. A plurality of posts between a valve actuating assembly in the module and a shut-off plate also in the module assures proper seating of the shut-off plate in the base of the valve.
