  • THIS invention relates to a pool cleaner accessory.
  • the invention concerns a pool cleaner accessory for use in suction pool cleaners of the type making use of a suction hose to feed water from a cleaning head of the pool cleaner to a filter.
  • suction cleaners which comprise a cleaning head which is submerged in a swimming pool.
  • the cleaning head is connected to a pump with the use of a suction hose.
  • the pump is typically in fluid communication with a sand filter.

  • the water which is drawn from the swimming pool into the cleaning head will normally include any debris that may lie on the surface of the swimming pool. When the water enters the sand filter the debris will be removed and the water, now free of any debris, will be re-circulated to the swimming pool.
  • the cleaning head In order to cause the cleaning head to move across the surface of a swimming pool, the cleaning head includes an actuating arrangement.
  • the actuating arrangement serves to open and close the mouth of the cleaning head periodically, such opening and closing creating pulses in the suction hose which in turn causes the cleaning head to undergo incremental movements along the surface of the swimming pool during each opening and closing cycle.

  • Valve 19 adjusted from its Open Position towards its Closed Position
  • the amount of water which is allowed to pass therethrough can be adjusted such that the rotational speed of a turbine 26, in this embodiment providing an energy source for the drive assembly 20, and as a consequence the speed at which the first conduit 12 can move relative to the second conduit 14, can be controlled.
  • the drive assembly 20 includes the turbine 26 which is pivotally secured inside a turbine chamber 28.
  • the turbine chamber 28 includes a first and a second inlet, indicated respectively with the reference numerals 30 and 32.
  • the drive assembly 20 also includes a transmission system 34 comprising a number of gears 36 for transmitting rotational movement of the turbine 26 to a second conduit gear 38.
  • the second conduit gear 38 meshes with a toothed rack 40 on the second conduit 14 such that when the transmission system 34 transmits rotational movement from the turbine 26, the second conduit gear 38 will rotate, thereby causing the first conduit 12 to move in a first direction relative to the second conduit 14.
