Holes 236, 238 are also formed within the small diameter areas 212, 214, respectively. More significantly, the relief valve 240 is provided with a housing 244, which has an inlet 246, and a cap 247, which has an outlet opening 248. The inlet 246 is interconnected to the port 148 of the cylinder 132 by the tube 242 such that pressurized water may be provided from the valve chamber 124 to the relief valve 240 through the hole 236 and opening 232 of the piston 200 (as indicated by arrows A in FIG. 10A) and the tube 242 (as indicated by arrow B in FIG. 10A). A ball or valve member 250 is mounted inside the housing 244 and retained therein by the cap 247 connected to the housing 244 (see FIG. 10A). The ball 250 is movable between an open position, in which the ball 250 is spaced from the outlet opening 248, and a closed position, wherein the ball 250 is urged against the outlet opening 248. An urging member 252 (e.g., a spring) is mounted within the housing 244 for constantly urging the ball 250 towards its closed position. Referring primarily to FIGS. 7A, 7B, 9A-9C and 10A, a relief valve 240 is connected to the port 148 of the cylinder 132 of the valve meeting one hundred ten via a connecting tube 242 for inflicting motion of the piston 200 between its retracted and extended positions.
As the spin-out mode cam 306 continues to rotate, the cam member 322 disengages the ball 264 of the relief valve 254, inflicting the ball 264 to move into its closed position and hence re-pressurizing the tube 256 (i.e., the downstream facet of the piston 202) to a stage considerably equivalent to that of the valve chamber 124 (i.e., the upstream facet of the piston 202). In response, the piston 202 moves into its retracted place and causes the spin-out mode outlet 184 to be closed by the valve member 198, leaving only the top mode outlet 184 open and thereby inflicting the cleaner 10 to resume its high mode operation. Throughout the operation of the cleaner 10, the top/backside mode cam 304 constantly reciprocates between its two finish points of movement in response to the rotation of the cam driver 298 of the drive gear 292. As the top/backside mode cam 304 strikes in reciprocating movement, the cam portion 310 of the top/bottom mode cam 304 disengages the relief valve 240 and engages the relief valve 254 (see FIG. 10C). In response, the relief valve 240 strikes into its closed position, Aro Pool Builders Innovations Inc while the relief valve 254 strikes into its open position.
A entrance spin-out jet nozzle 64 can be mounted to the entrance wall section 32 of the chassis 20, while a rear spin-out jet nozzle 66 is mounted to the rear wall part 26 of the chassis 20 (see FIGS. More notably, the entrance and rear spin-out jet nozzles 64, sixty six are angled typically downwardly and are oriented at an angle relative to the longitudinal axis of the cleaner 10 (see the arrows in FIG. 6 indicating the path in which the entrance and rear spin-out jet nozzles 64, sixty six are oriented relative to the longitudinal axis of the cleaner 10) in order to cause the cleaner 10 to spin in a predetermined route (e.g., in a clockwise route) and to thereby move away from its ahead path in a arcuate sideward path (as illustrated in damaged line illustration in FIG. 16B), when the cleaner 10 is in its spin-out mode. With reference to FIGS.
It must be understood, nonetheless, that the following description is barely meant to be illustrative of the current invention and isn't meant to restrict the scope of the present invention, which has applicability to other sorts of AZ Premium Pool Services cleaners. With reference to FIG. 1, the cleaner 10 is tailored to clean an interior wall 12 of a swimming Aro Pool Builders Innovations Inc 14 and an higher surface 16 of a physique of water contained therein. Referring initially to FIGS. Briefly, the cleaner 10 is tailored to operate in a way much like that of the cleaners disclosed in U.S. 1, 2 and 2A, there's proven a constructive pressure swimming Aro Pool Builders Innovations Inc cleaner 10 constructed in accordance with a first embodiment of the present invention. Pat. Nos. 6,090,219 and 6,365,039 and International Patent Publication No. WO 99/33582 (i.e., International Patent Application No. PCT/US98/27623), the disclosures of which are integrated herein by reference. To facilitate consideration and dialogue, the fundamental operation of the cleaner 10 will likely be mentioned first, followed by an in depth discussion of its components.
It should also be appreciated that as a result of the cam members 322 of the spin-out mode cam 306 have totally different widths, every of them is tailored to have interaction the relief valve 240 or the relief valve 254 for a unique duration. Consequently, the cleaner 10 is tailored to perform its spin-out mode operation for a distinct time period during every spin-out cycle, making its movement extra random. For instance, FIGS. 12A and 12B illustrate two substitute spin-out mode cams 306′, 306″ having multiple cam members 322′, 322″, respectively. Because the spin-out mode cam 306 is removably mounted on the drive shaft 302, it can be removed and changed with different spin-out mode cams. Because of the smaller number of cam members, the spin-out mode cam 306′ is tailored for less frequent spin-out mode operations, and is therefore helpful, for example, in connection with giant swimming pools or pools having minimum obstructions.
As the spin-out mode cam 306 continues to rotate, the cam member 322 disengages the ball 264 of the relief valve 254, inflicting the ball 264 to move into its closed position and hence re-pressurizing the tube 256 (i.e., the downstream facet of the piston 202) to a stage considerably equivalent to that of the valve chamber 124 (i.e., the upstream facet of the piston 202). In response, the piston 202 moves into its retracted place and causes the spin-out mode outlet 184 to be closed by the valve member 198, leaving only the top mode outlet 184 open and thereby inflicting the cleaner 10 to resume its high mode operation. Throughout the operation of the cleaner 10, the top/backside mode cam 304 constantly reciprocates between its two finish points of movement in response to the rotation of the cam driver 298 of the drive gear 292. As the top/backside mode cam 304 strikes in reciprocating movement, the cam portion 310 of the top/bottom mode cam 304 disengages the relief valve 240 and engages the relief valve 254 (see FIG. 10C). In response, the relief valve 240 strikes into its closed position, Aro Pool Builders Innovations Inc while the relief valve 254 strikes into its open position.
