This is a non-provisional patent utility relating to U.S. U.S. Pat. Nos. 6,090,219 and 6,365,039 and International Patent Publication No. WO 99/33582 disclose swimming pool cleaners adapted to rise proximate to a water floor of a pool for removing floating debris therefrom and to descend proximate to a wall surface of the pool for removing debris therefrom (see additionally U.S. The present invention overcomes the disadvantages and shortcomings talked about above by providing an improved swimming pool cleaning gadget having a fluid distribution system for controlling its operation. Accordingly, there may be a need for a pool cleaner outfitted with an enhanced control mechanism for controlling the operation of the cleaner. The present invention relates to swimming pool cleaning apparatus and parts useful in connection therewith. There can be need for different improvements for enhancing the operation of the pool cleaner. Pat. Nos. 6,039,886 and 6,387,250 and International Patent Publication No. WO 99/34077). These cleaners utilize pretty sophisticated and/or complex mechanisms for controlling their water surface cleaning and wall floor cleansing operations.

In such circumstances, the cleaner 1010 is devoid of the components of the embodiment of FIGS. With reference to FIGS. 18, 20A and 20B, poolcontractorsquotes.com the cleaner 1010 is outfitted with only one relief valve 1240 for operating a piston 1200 so as to move a valve member 1196 between a bottom mode position, during which the valve member 1196 is positioned over a spin-out mode outlet 1184 of a valve housing 1122 (see FIG. 20A), and a spin-out mode place, wherein the valve member 1196 is positioned over a bottom mode outlet 1160 of the valve housing 1122 (see FIG. 20B). While the cleaner 1010 is supplied with a piston 1202, it remains in its prolonged position all through the operation of the cleaner 1010 so as to always position a valve member 1198 over a high mode outlet 1170 (see FIGS. Because a unique sort of filter bag is used in reference to the cleaner 1010 (as might be mentioned in greater detail hereinafter), debris retention jets are usually not included within the cleaner 1010. In such circumstances, the cleaner 1010 just isn't supplied with a nose gear. 1-16B related to the highest mode operation. As an example, the cleaner 1010 is not provided with a raise/thrust jet nozzle or skimmer jets.

The cleaner 3010 can also be equipped with a drive shaft 3302 and a spin-out cam 3306 mounted on the drive shaft 3302 for engaging a relief valve 3240 so as to trigger the cleaner 3010 to periodically go into its spin-out mode. It will likely be understood that the embodiments described herein are merely exemplary and that a person skilled in the art could make many variations and modifications without departing from the spirit and scope of the invention. 26 and 27). The cam participating surfaces 3428 are positioned such that when the spin-out cam 3306 is placed on the drive shaft 3302 with the aspect 3430 dealing with upwardly, solely the cam partaking surfaces 3428 are engageable with the relief valve 3240. Likewise, Long Island Swim-Pool Service the cam partaking surfaces 3432 are positioned such that when the spin-out cam 3306 is placed on the drive shaft 3302 with the facet 3434 facing upwardly, solely the cam engaging surfaces 3432 are engageable with the relief valve 3240. Each of the cam partaking surfaces 3428 has a width, and hence a spin-out duration, different from the width Yaku Pools and Construction - San Fernando Valley the spin-out duration of the cam partaking surfaces 3432. In consequence, the aspect 3430 of the spin-out cam 3306 (i.e., the cam engaging surfaces 3428) has a spin-out "program" totally different from the spin-out "program" related to the facet 3434 (i.e., the cam engaging surfaces 3432) of the spin-out cam 3306. As an illustration, the aspect 3430 of the spin-out cam 3306, which have a wider width and therefore a longer spin-out duration, is suitable for summer time use, while the aspect 3434 of the spin-out cam 3306, which has a shorter width and hence a shorter spin-out duration, is appropriate for INC. winter use. A screw 3426 removably secures the spin-out cam 3306 to the drive shaft 3302. The spin-out cam 3306 has a plurality of cam members 3322, every of which has a cam partaking floor 3428 on one facet 3430 of the spin-out cam 3306 and a cam partaking surface 3432 on an reverse facet 3434 of the spin-out cam 3306 (see FIGS. All such variations and modifications, including those discussed above, are meant to be included throughout the scope of the invention as outlined within the appended claims.

The piston has a passage extending thereth rough in order to permit circulation of pressurized fluid from the valve chamber to the second aspect of the piston chamber. A minimum of one valve is in fluid communication with the second facet of the piston chamber such that when the valve is in a closed situation, the second side of the piston chamber is pressurized by pressurized fluid flowing from the valve chamber to the second side of the piston chamber through the passage of the piston so as to cause the piston to maneuver to the primary position and such that when the valve is in an open condition, the second facet of the piston chamber is depressurized in order to cause the piston to move to the second position. On this manner, move of pressurized fluid from the valve chamber to one of the outlet openings is selectively controlled by causing the valve to be in the open or closed condition.
