Pressurized fluid apparatus
First Claim
1. Pressurized fluid apparatus comprising:
- a pressurized fluid container;
a pipe arranged for flow therethrough of said pressurized fluid into said container;
a valve operatively connected to an end of said pipe disposed in said container; and
a branch in fluid communication with said fluid container adapted for flow therethrough of fluid from said fluid container for consumer use;
a float attached to said 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 float, said valve and said branch are insertable through an upper opening of said container as a single unit, and wherein said valve 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, and 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.

Abstract
Pressurized fluid apparatus including a pressurized fluid container, a pipe arranged for flow therethrough of the pressurized fluid into the container, a valve operatively connected to an end of the pipe disposed in the container, and a float attached to the valve, wherein the float is buoyed generally upwards by the pressurized fluid filling the container, such that when the float has been moved a predetermined amount, the float closes the valve and substantially stops flow of the pressurized fluid into the container, and wherein the float is insertable through an upper opening of the container, and wherein the valve is rotatably attached to the pipe, the valve being closed by an angular upward movement of the float, characterized by the valve including a tube with a longitudinal bore having a longitudinal axis formed therein, and a piston slidingly disposed in the tube, wherein only when the float is generally perpendicular to the longitudinal axis, the piston sealingly abuts an internal end face of the tube, thereby closing the valve.
