    Abstract: THE INVENTION RELATES TO A MOTOR-COMPRESSOR ASSEMBLY OF THE TYPE USED FOR SMALL REFIGERATING MACHINES. THE ASSEMBLY HAS A VERTICAL CRANKSHAFT ARRANGEMENT WITH A CARRIER FRAME BEING FORMED WITH RADIAL AND AXIAL THRUST BEARINGS TO PROVIDE LATERAL AND VERTICAL SUPPORT FOR THE CRANKSHAFT. A DETACHABLE BEARING MEMBER IS ATTACHED TO THE UPPER PORTION OF THE CRANKSHAFT WHICH HAS AN ANNULAR BEARING SURFACE FOR ENGAGEMENT WITH SAID AXIAL THRUST BEARING AND COMPENSATING WEIGHT MEANS FOR COUNTERBALANCING THE CRANK PORTION OF THE CRANKSHAFT.

    Abstract: AN ENCAPSULATED REFRIGERATION MOTOR-COMPRESSOR HERMETICALLY SEALED IN A CAPSULE AND IN WHICH THE MOTOR IS COOLED BY A SEPARATE OIL FLOW THAN THAT LUBRICATING THE COMPRESSOR. THE TWO INDEPENDENT OIL FLOWS ARE TAKEN FROM A COMMON OIL PUMP BY A TWIN CENTRIFUGAL PUMP. THE MOTOR HAS A VERTICALLY DISPOSED HOLLOW MOTOR SHAFT TO WHICH IS ATTACHED A LENGTH OF TUBING IN COMMUNICATION WITH THE BORE OF THE SHAFT DEFINING A FIRST CENTRIFUGAL OIL PUMP. A SECOND LENGTH OF TUBING IS MOUNTED CIRCUMFERENTIALLY AND AXIALLY OF THE FIRST-MENTIONED LENGTH OF TUBING SPACED OUTWARDLY THEREFROM DEFINING A SECOND CENTRIFUGRAL OIL PUMP DRIVEN IN CONJUNCTION WITH THE FIRST PUMP FROM THE COMMON MOTOR SHAFT. A SINGLE CENTRIFUGRAL PUMP CONSISTING OF A SINGLE LENGTH OF TUBING CAN PROVIDE THE TWO OILS FLOWS BY CONSTRUCTING IT WITH AN AXIALLY EXTENDING ENLARGMENT AT THE ZONE OF DIVISION OF THE DISCHARGE INTO TWO OUTPUT FLOWS.
