Abstract:
Pressurized fluid apparatus comprising:a pressurized fluid container;a pipe arranged for flow therethrough of a pressurized fluid into said container;a valve mechanism operatively connected to an end of said pipe disposed in said container;a branch influid communiation with said fluid container adapted for flow therethrough of fluid from said fluid container for consumer use; andsaid mechanism having a float attached to a valve, wherein said float is buoyed generally upwards by said pressurized fluid filling said container, such that when said float has been moved a predetermined amount, said float closes said valve and substantially stops flow of said pressurized fluid into said container, and wherein said valve mechanism, said branch and said pipe are insertable through an upper opening of said container as a single unit, and wherein said valve mechanism is rotatably attached to said pipe, said valve being closed by an angular upward movement of said float;characterized by said valve comprising:a tube with a longitudinal bore having a longitudinal axis formed therein, andsaid valve including a piston slidingly disposed in said tube, wherein only when said float is generally perpendicular to said longitudinal axis, said piston sealingly abuts an internal end face of said tube, thereby closing said valve;said pressurized fluid apparatus further comprising:a bypass passageway extending along and around at least a portion of said pipe in fluid communication with said branch for conducting therethrough fluid to said branch for consumer use, even during filling of said container through said pipe.
