Abstract:
1. A high-pressure fluid conduit adapted for connection between a high-pressure fluid source and a high-pressure fluid container, said high-pressure fluid conduit comprising: a hose unit having a first end and a second end; a first housing adapted for connection to a high-pressure fluid source and having: (a) a first fluid opening through which high-pressure fluid from the high-pressure fluid source enters said first housing, (b) a second fluid opening through which high-pressure fluid from the high pressure fluid source leaves said first housing and enters said hose unit, and (c) a cavity between said first fluid opening in said first housing and said second fluid opening in said first housing; a second housing adapted for connection to a high-pressure fluid container and having: (a) a first fluid opening through which: (b) a second fluid opening through which: (c) a cavity between said first fluid opening in said second housing and said second fluid opening in said second housing; an annular ring: (a) coupling at least one of: (b) having a weakened section extending around said annular ring that fractures when a predetermined force is applied to said annular ring that causes first and second parts of said annular ring on opposite sides of said weakened section to separate; a first valve seat at said second fluid opening in said first housing; a second valve seat at said first fluid opening in said second housing; a first valve body pivotally mounted in said cavity of said first housing and movable between: (a) a first position to permit the flow of the high-pressure fluid from the high-pressure fluid source through said first housing, and (b) a second position against said first valve seat in said first housing to prevent high-pressure fluid leaving said first housing; a second valve body pivotally mounted in said cavity of said second housing and movable between: (a) a first position to permit the flow of the high-pressure fluid from the high-pressure fluid source through said second housing, and (b) a second position against said second valve seat in said second housing to prevent the flow of high-pressure fluid from the high-pressure fluid container leaving said second housing; and valve control means for: (a) retaining said first valve body in its first position and said second valve body in its first position, and (b) selectively moving said first valve body to its second position and said second valve body to its second position in response to fracture of said annular ring and separation of said first and second parts of said annular ring on opposite sides of said weakened section of said annular ring.
