Cooling system for rotary mechanisms

Claim 1

A ROTARY MECHANISM FOR FLUID MOTORS, ROTARY FLUID PUMPS, ROTARY COMBUSTION ENGINES OR THE LIKE, COMPRISING AN OUTER BODY HAVING A MULTI-LOBED CAVITY COAXIAL THEREWITH, A SHAFT MEMBER HAVING AN ECCENTRIC PORTION DISPOSED WITHIN SAID CAVITY AND HAVING AN AXIS PARALLEL TO THE CAVITY AXIS AND ECCENTRIC THERETO, A HOLLOW ROTOR MOUNTED ON SAID ECCENTRIC AND DISPOSED WITHIN THE CAVITY FOR ROTATION RELATIVE TO THE CAVITY AND TO THE ECCENTRIC PORTION AND HAVING A PLURALITY OF CIRCUMFERENTIALLY-SPACED APEX PORTIONS HAVING SEALING COOPERATION WITH THE PERIPHERAL WALL OF THE CAVITY TO FORM A PLURALITY OF WORKING CHAMBERS BETWEEN THE ROTOR AND THE OUTER BODY THAT CONTAIN A WORKING FLUID AND THAT VARY IN VOLUME UPON RELATIVE ROTATION BETWEEN THE ROTOR AND THE OUTER BODY, THE ROTOR BEING RADIALLY SYMMETRICAL ABOUT ITS AXIS AND HAVING ONE MORE APEX PORTION THAN THE CAVITY HAS LOBES, A COOLING SYSTEM COMPRISING AN INLET PASSAGE SUBSTANTIALLY PARALLEL TO THE AXIS OF THE CAVITY FOR SUPPLYING A COOLING LIQUID TO THE ROTARY MECHANISM, A SECOND PASSAGE COMMUNICATING WITH THE INLET PASSAGE FOR SUPPLYING THE COOLING LIQUID TO THE HOLLOW INTERIOR OF THE ROTOR, THE COOLING LIQUID BEING CARRIED BY CENTRIFUGAL FORCE TO THE RADIALLY OUTER SURFACE OF THE HOLLOW INTERIOR OF THE ROTOR DURING ROTOR ROTATION, A STATIONARY MEMBER EXTENDING RADIALLY OUTWARDLY FROM THE AXIS OF THE OUTER BODY CAVITY INTO THE HOLLOW INTERIOR OF THE ROTOR AND HAVING A RADIUS SMALLER THAN THE RADIUS OF THE HOLLOW INTERIOR OF THE ROTOR AND HAVING A RADIAL PASSAGE OPEN AT ITS PERIPHERY, AN OUTLET PASSAGE SUBSTANTIALLY PARALLEL TO THE AXIS OF THE CAVITY AND COMMUNICATING WITH THE RADIALLY INNER END OF THE RADIAL PASSAGE, THE RADIAL PASSAGE BEING AT LEAST INTERMITTENTLY IMMERSED IN THE COOLING LIQUID DISTRIBUTED BY CENTRIFUGAL FORCED AROUND THE RADIALLY OUTER SURFACE OF THE HOLLOW INTERIOR OF THE ROTOR, THE COOLING LIQUID BEING FORCED BY CENTRIFUGALLY GENERATED PRESSURE RADIALLY INWARD THROUGH THE RADIAL PASSAGE AND INTO THE OUTLET PASSAGE, WHEREBY THE COOLING LIQUID IS CONTINUOUSLY INTRODUCED INTO AND REMOVED FROM THE HOLLOW INTERIOR OF THE ROTOR.
