Cooling system for rotary mechanisms

Claim 1

A ROTARY MECHANISM COMPRISING A HOLLOW OUTER BODY HAVING AN AXIS, AXIALLY-SPACED END WALLS AND A PERIPHERAL WALL INTERCONNECTING THE END WALLS, A ROTOR MOUNTED WITHIN THE OUTER BODY FOR ROTATION RELATIVE TO THE OUTER BODY ON AN AXIS ECCENTRIC FROM AND PARALLEL TO THE AXIS OF THE OUTER BODY, THE ROTOR BEING SYMMETRICAL ABOUT ITS AXIS, HAVING END FACES DISPOSED ADJACENT TO THE END WALLS AND A PLURALITY OF CIRCUMFERENTIALLY-SPACED APEX PORTIONS IN SEALING ENGAGEMENT WITH THE INNER SURFACE OF THE PERIPHERAL WALL TO FORM A PLURALITY OF WORKING CHAMBERS BETWEEN THE ROTOR AND THE PERIPHERAL WALL THAT VARY IN VOLUME UPON RELATIVE ROTATION OF THE ROTOR WITHIN THE OUTER BODY, THE ROTOR HAVING AN INTERNAL CAVITY FOR THE FLOW OF A COOLING FLUID THROUGH THE ROTOR, A STATIONARY MEMBER EXTENDING RADIALLY OUTWARD INTO THE INTERNAL CAVITY OF THE ROTOR, THE STATIONARY MEMBER HAVING A PLURALITY OF PASSAGES OPEN AT THEIR RADIALLY OUTER ENDS SO THAT WHEN THESE OUTER ENDS ARE IMMERSED IN FLUID WITHIN THE ROTOR THE CENTRIFUGAL PRESSURE ON THE FLUID IS EFFECTIVE TO FORCE THE FLUID TO FLOW OUT OF THE ROTOR THROUGH THE STATIONARY PASSAGES, THE INTERNAL CAVITY OF THE ROTOR BEING SYMMETRICAL ABOUT THE ROTOR AXIS AND HAVING A NON-CIRCULAR SHAPE THAT IS GENERALLY SYMMETRICAL TO THE SHAPE OF THE ROTOR ITSELF, THE STATIONARY MEMBER HAVING A PERIPHERY THAT HAS SUBSTANTIALLY THE SHAPE OF THE INNER ENVELOPE CURVE THAT IS CIRCUMSCRIBED BY THE OUTER CONTOUR OF THE ROTOR CAVITY DURING ROTATION OF THE ROTOR RELATIVE TO THE OUTER BODY, AND THE RADIALLY OUTER ENDS OF THE PASSAGES BEING LOCATED ON THE PERIPHERY OF THE STATIONARY MEMBER.
