Abstract
A pool cleaner reed valve for a pulsating submersible swimming pool cleaner which has a valve body ( ) configured to fit into a pulsating valve enclosure. The body includes a rectangular inlet end ( ) and an round outlet end ( ) with a pair of fulcrum points ( ) and restricting boundaries ( ) for retaining and confining valve movements. A pair of opposed rigid valve plates ( ) are angularly juxtaposed within the valve inlet end contiguously engaging the fulcrum points and respective restricting boundaries such that each opposed blade rotates inwardly on the fulcrum point until the distal ends intimately engage as influenced by negative fluid pressure applied by a pool pump. A pair of torsion springs ( ) surround each restricting boundary and interface with each valve plate returning them to a parallel position when fluid pressure is terminated. A resilient sleeve ( ) is positioned on each spring for eliminating a metal to metal contact with the spring to the valve plate.
