Abstract
A cleaner for swimming pools includes a housing having a pressure differential chamber with an opening defined by opposing walls and an oscillator pivotally mounted within the opening on a pivot axis extending between the walls. A seal is loosely fitted within a recess along a side of the oscillator for movement outwardly across a gap between the oscillator and the wall of the opening to close the gap when necessary for purposes of starting the oscillator and for opening the gap when required to allow grit, leaves and the like to pass through.
Claims20
A submersible cleaner for swimming pools comprising:
- a housing including a chamber therein having an opening defined by opposing walls through which opening water flows during operation of the cleaner;
- an oscillator having opposing ends and pivotally mounted in the opening of the housing on a pivot axis extending between the opposing walls for continuous oscillatory movement to and fro within the opening responsive to the flow of water across the ends of the oscillator, the oscillator including a first side facing a first one of the walls with a gap therebetween;
- sealing means slidably fitted with the first side of the oscillator and slidable outwardly in a direction generally parallel with the pivot axis into engagement with the first wall;
- and wherein
- the sealing means is at least partially exposed to the flow of water through the chamber.
A submersible cleaner for swimming pools comprising:
- a housing including a chamber having an opening defined by opposing walls through which opening water flows during operation of the cleaner;
- an oscillator having opposing ends, the oscillator pivotally mounted in the opening on a pivot axis between the walls for oscillatory movement to and fro within the opening responsive to the flow of water across the oscillator, the oscillator including a first side facing one of the walls of the opening and having retaining means extending generally parallel with the pivot axis;
- sealing means slidably fitted with the retaining means adjacent the first side of the oscillator and alternately slidable inwardly and outwardly in a direction generally parallel with the pivot axis and into and out of engagement with the one wall of the housing;
- and wherein
- the retaining means is substantially oversized with respect to the sealing means, such that the sealing means fits loosely within the retaining means in order to insure that the functioning of the sealing means is not impeded by grit and other material.

- and wherein
- the oscillator includes retaining means at each of the opposing ends thereof for holding the sealing means into slidable engagement with the oscillator.
