Holes 236, 238 are also formed in the small diameter areas 212, 214, respectively. More significantly, the relief valve 240 is supplied 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 will be equipped from the valve chamber 124 to the relief valve 240 by way of the opening 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 throughout the housing 244 and retained therein by the cap 247 attached to the housing 244 (see FIG. 10A). The ball 250 is movable between an open place, in which the ball 250 is spaced from the outlet opening 248, and a closed position, through which the ball 250 is urged towards the outlet opening 248. An urging member 252 (e.g., a spring) is mounted in 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 related to the port 148 of the cylinder 132 of the valve meeting 110 via a connecting tube 242 for inflicting motion of the piston 200 between its retracted and prolonged positions.
Because the spin-out mode cam 306 continues to rotate, the cam member 322 disengages the ball 264 of the relief valve 254, causing the ball 264 to maneuver into its closed place and hence re-pressurizing the tube 256 (i.e., the downstream facet of the piston 202) to a degree considerably an identical to that of the valve chamber 124 (i.e., the upstream aspect 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 solely the highest 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 continuously 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 highest/backside 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 place, whereas the relief valve 254 moves into its open place.
A front spin-out jet nozzle sixty four is also mounted to the entrance wall part 32 of the chassis 20, while a rear spin-out jet nozzle sixty six is mounted to the rear wall section 26 of the chassis 20 (see FIGS. More particularly, the front 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 direction by which the front and rear spin-out jet nozzles 64, sixty six are oriented relative to the longitudinal axis of the cleaner 10) in order to trigger the cleaner 10 to spin in a predetermined course (e.g., in a clockwise route) and to thereby transfer away from its ahead path in a arcuate sideward path (as illustrated in broken line representation in FIG. 16B), when the cleaner 10 is in its spin-out mode. With reference to FIGS.
It ought to be understood, nevertheless, that the next description is simply meant to be illustrative of the present invention and isn't meant to restrict the scope of the present invention, which has applicability to different sorts of Houston pool cleaning services cleaners. With reference to FIG. 1, the cleaner 10 is adapted to scrub an inside wall 12 of a swimming Orlando weekly pool maintenance 14 and an higher surface sixteen of a physique of water contained therein. Referring initially to FIGS. Briefly, the cleaner 10 is tailored to function in a way much like that of the cleaners disclosed in U.S. 1, 2 and 2A, there may be proven a positive stress swimming 24 hour pool services California cleaner 10 constructed in accordance with a primary embodiment of the current 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 that are incorporated herein by reference. To facilitate consideration and dialogue, the basic operation of the cleaner 10 shall be mentioned first, followed by a detailed dialogue of its elements.
It should also be appreciated that because the cam members 322 of the spin-out mode cam 306 have different widths, every of them is adapted to engage the relief valve 240 or the relief valve 254 for a special duration. Because of this, the cleaner 10 is adapted to perform its spin-out mode operation for a distinct time interval during each spin-out cycle, making its movement extra random. As an example, FIGS. 12A and 12B illustrate two alternative spin-out mode cams 306′, Pool builders Houston TX 306″ having multiple cam members 322′, 322″, respectively. Because the spin-out mode cam 306 is removably mounted on the drive shaft 302, it may be removed and changed with different spin-out mode cams. Because of the smaller variety of cam members, the spin-out mode cam 306′ is adapted for much less frequent spin-out mode operations, and is therefore helpful, as an illustration, in connection with large pools or pools having minimal obstructions.
Because the spin-out mode cam 306 continues to rotate, the cam member 322 disengages the ball 264 of the relief valve 254, causing the ball 264 to maneuver into its closed place and hence re-pressurizing the tube 256 (i.e., the downstream facet of the piston 202) to a degree considerably an identical to that of the valve chamber 124 (i.e., the upstream aspect 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 solely the highest 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 continuously 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 highest/backside 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 place, whereas the relief valve 254 moves into its open place.
