Cooling system for a rotary mechanism

Claim 1

IN A ROTARY MECHANISM FOR FLUID PUMPS, FLUID MOTORS, COMBUSTION ENGINES OR THE LIKE COMPRISING AN OUTER BODY WITH A CAVITY THEREIN, A ROTATABLE SHAFT MOUNTED IN SAID OUTER BODY CO-AXIAL WITH THE AXIS OF THE PERIPHERAL WALL OF THE OUTER BODY CAVITY AND HAVING AN ECCENTRIC PORTION THEREON, A ROTOR JOURNALLED ON SAID ECCENTRIC PORTION FOR ROTATION ABOUT ITS AXIS WHILE SAID ROTOR AXIS DESCRIBES A PLANETARY MOTION RELATIVE TO THE AXIS OF SAID OUTER BODY WHEREBY EACH POINT ON SAID ROTOR IS SUBJECTED TO ACCELERATION FORCES WHICH SUCCESSIVELY CHANGE IN DIRECTION RELATIVE TO THE AXIS OF SAID ROTOR, SAID ROTOR HAVING A PERIPHERAL SURFACE FORMING A PLURALITY OF CIRCUMFERENTIALLY-SPACED APEX PORTIONS FOR SEALING ENGAGEMENT WITH THE INNER SURFACE OF SAID PERIPHERAL WALL AND THEREBY FORMING WORKING CHAMBERS BETWEEN THE ROTOR PERIPHERAL SURFACE AND THE PERIPHERAL WALL OF SAID CAVITY WHICH UPON RELATIVE ROTATION OF SAID OUTER BODY AND SAID ROTOR VARY IN VOLUME, SAID ROTOR HAVING AN OUTER WALL INCLUDING A HUB PORTION ENCLOSING A HOLLOW INTERIOR AND HAVING A PLURALITY OF CIRCUMFERENTIALLY-SPACED GENERALLY-RADIAL PARTITIONS THEREIN FORMING COMPARTMENTS IN SAID ROTOR, MEANS INCLUDING OPENINGS THROUGH THE ROTOR OUTER WALL AND DISPOSED ADJACENT TO SAID HUB PORTION AT THE RADIALLY INNER PORTIONS OF SAID COMPARTMENTS FOR SUPPLYING A LIQUID COLLANT SEQUENTIALLY INTO SAID ROTOR COMPARTMENTS AND FOR SEQUENTIALLY DRAINING SAID COOLANT FROM SAID ROTOR COMPARTMENTS AS THE ROTOR ROTATES ABOUT ITS AXIS SUCH THAT EACH COMPARTMENT RECEIVES A MAJOR PORTION OF ITS LIQUID COOLANT DURING A PORTION OF EACH REVOLUTION OF THE ROTOR AND EACH COMPARTMENT DRAINS A MAJOR PORTION OF SAID COOLANT DURING OTHER PORTIONS OF EACH REVOLUTION OF THE ROTOR.
