Abstract

A pool cleaning system including means responsive to the magnitude of negative pressure at the suction inlet of a system pump for controlling pump water flow in order to prevent pump cavitation. Systems in accordance with the invention are configured to pump a high rated volume of water when operating in a filtering mode and to provide a high negative pressure to power a pool cleaner when operating in a cleaning mode.

Description

RELATED INVENTIONS

[0001] This application is a continuation of PCT2006 / 027495 filed 13 Jul. 2006 which claims priority based on U.S. Application 60 / 705,080 filed 8 Feb. 2005. This application claims priority based on the aforementioned applications.FIELD OF THE INVENTION

[0002] This invention relates generally to a swimming pool cleaning system utilizing an electrically driven pump for powering (1) a pool water filtration system and (2) an automatic pool cleaner; and more particularly to system improvements for preventing pump cavitation and for increasing the negative operating pressure (i.e., suction) available for powering the pool cleaner.BACKGROUND OF THE INVENTION

[0003] Typical pool cleaning systems include an electrically driven pump which draws pool water into its suction inlet and discharges the water from its pressure outlet. The pool water drawn into the pump inlet is most typically captured by a pool skimmer and / or drain. The pool water discharged from the pump outlet is typ...
