Claims

1. IN COMBINATION, A ROTOR HAVING AN OUTER CYLINDRICAL SURFACE, A STATOR SUBSTANTIALLY ENVELOPING SAID ROTOR, AND INCLUDING FIVE AXIALLY SPACED BEARING PORTIONS, THE FIRST AND FIFTH BEARING PORTIONS BEING OF EQUAL WIDTH AND BEING CONCENTRIC TO EACH OTHER, THE SECOND AND FOURTH BEARING PORTIONS BEING OF EQUAL WIDTH TO THE FIRST AND FIFTH BEARING PORTIONS AND BEING CONCENTRIC WITH ONE ANOTHER, AND A THIRD BEARING PORTION HAVING A BEARING WIDTH TWICE THAT OF THE FIRST BEARING PORTION, THE CENTERS OF THE GROUPS OF BEARING PORTIONS BEING EQUALLY SPACED ON A CIRCLE SUBSTANTIALLY CONCENTRIC WITH THE ROTOR AXIS, SAID BEARING PORTIONS DEFINING A PLURALITY OF SURFACES CONVERGING TOWARD THE CYLINDRICAL SURFACE OF THE ROTOR, MEANS FOR SUPPLYING FLUID BETWEEN THE STATOR AND THE ROTOR, ROTATION OF THE ROTOR CAUSING THE GENERATION OF HIGH PRESSURES IN THE CONVERGING AREAS BETWEEN THE ROTOR AND THE STATOR, THE RESULTANT FORCES OF EACH SAID HIGH PRESSURE AREAS ACTING UPON MAJOR PORTIONS OF THE ANNULAR SURFACE OF THE ROTOR TO STABILIZE THE ROTOR IN SAID STATOR TO SUBSTANTIALLY LIMI THE MOVEMENT OF THE AXIS OF THE ROTOR DURING ROTATION THEREOF.
