Abstract: The invention relates to a method for making an oil pump for refrigeration machines. The pump comprises a tube formed by drawing which is press fitted into the bore of a motor rotor. The tube is initially formed with an inwardly domed, closed end portion. Circumferentially and radially extending incisions are made in the domed end portion to form cantilever portions which in turn are bent inwardly relative to the end of the tube to form blades.

Abstract: THE INVENTION RELATES TO A LUBRICATING SYSTEM FOR A MOTORCOMPRESSOR ASSEMBLY OF THE TYPE USED FOR SMALL REFRIGERATING MACHINES. THE ASSEMBLY HAS A VERTICAL SHAFT ARRANGEMENT WITH A CENTRIFUGING DISC ATTACHED TO THE TOP OF THE SHAFT FOR FLINGING LUBRICATING OIL TO THE INTERNAL WALL OF THE CASING BY CENTRIFUGAL FORCE. THE SHAFT HAS SHOULDER OR FLANGE WHICH FORMS A PART OF AN AXIAL THRUST BEARING ARRANGEMENT AND THE CENTRIFUGING DISC HAS OUTWARDLY INCLINED WALL MEANS WHICH EXTENDS FROM A LEVEL BELOW TO A LEVEL ABOVE THE SHOULDER OF THE SHAFT.
