Magnet actuated sealed valve

Claim 1

IN A PACKLESS VALVE OF THE CONCENTRIC CYLINDRICAL MAGENET ACTUATED TYPE, THE COMBINATION OF A VALVE CASING HAVING INFLUENT AND EFFLUENT PORTS, A GENERALLY CYLINDRICAL VALVE PLUG SEAT INTERMEDIATE OF SAID CASING BETWEEN SAID PORTS, THE AXIS OF SAID SEAT BEING TRANSVERSE TO THE FLOW PATH THROUGH SAID CASING, AND A CYLINDRICAL ENCLOSURE EXTENDING FROM SAID CASING, COAXIALLY WITH SAID SEAT, SAID ENCLOSURE FORMING A SEALED CHAMBER OPENING INTO SAID ENCLOSURE FORMING A MAGNETIC ROTARY COUPLING MEANS COMPRISING AN INNER, HOLLOW, CYLINDRICAL SLEEVE ROTATABLE WITHIN SAID SEALED CHAMBER AND AN OUTER, HOLLOW, CYLINDRICAL SLEEVE ROTATABLE AROUND THE EXTERIOR OF SAID ENCLOSURE, SAID INNER SLEEVE HAVING AN AXIAL BORE OF PREDETERMINED DIAMETER AND BEING OF LESS HEIGHT THAN THE HEIGHT OF OF SAID CHAMBER TO FLOAT VERTICALLY THEREIN; AN ELONGATED HOLLOW THE TUBE MOUNTED WITHIN SAID CASING, SAID TUBE HAVING AN APERTURED LOWER PORTION ROTATABLE IN SAID SEAT TO FORM A VALVE PLUG, AND HAVING ITS UPPER PORTION LOOSELY FITTED WITHIN THE AXIAL BORE OF SAID INNER MAGNET FOR SLIGHT AXIAL AND TRANSVERSE MOTION RELATIVE THERETO, AND LOOSE FIT ATTACHMENT MEANS CONNECTING SAID INNER MAGNET TO THE UPPER PORTION OF SAID TUBE FOR TRANSMITTING ROTARY MOTION ONLY THEREBETWEEN, WHEREBY ROTATION OF SAID OUTER MAGNETIC SLEEVE CAUSES ROTATION OF SAID INNER MAGNETIC SLEEVE AND VALVE PLUG TO ACTUATE SAID VALVE WHILE SAID INNER MAGNET IS FREE TO FLOAT AXIALLY AND FREE TO AXIALLY DIRECTED FORCES THEREON.
