Abstract
A swimming pool pressure cleaner ( ) of the type motivated by water flow through it having: a set of two wheels ( ) rotatably mounted to the body ( ); a turbine housing ( ) having a water-flow chamber ( ) with an inlet ( ) and an outlet ( ), the inlet held in proximity to the pool surface ( ); a vaned rotor ( ) rotatably mounted in the chamber; one or more one venturi jets ( ) secured to the body and oriented to direct water into the inlet to rotate the turbine and cause flow from the pool into the inlet; a drive member ( ) secured to the rotor and a drive train extending to the wheels for synchronous rotation on the pool surface; a cam ( ) rotatably secured to the body and driven by the rotor through reduction gearing ( ); and a linkage ( ) from the cam to one wheel ( ) to periodically interrupt the synchronous rotation of the wheels on the pool surface and change pool cleaner direction.
