Zusammenfassung:	IN ORDER TO REDUCE LEKAGE OF A REFRIGERENT CAUSED BY CHANGES IN PRESSURE DIFFERENCES BETWEEN COMPRESSION ELEMENTS AND ACHIVE AN INCREASE IN VOLUMETRIC EFFICIENTCY AND COMPRESSOR EFFICIENTCY OF A TWO STAGE COMPRESSOR, A ROTARY TYPE TWO STAGE COMPRESSOR COMPRISES AN ELECTIC MOTOR RECEIVED INA CLOSED VESSEL, ROTATING COMPRESSION ELEMENTS PROVIDED BY STACKING A LOW-PRESSURE COMPRESSION ELEMENT AND A HIGH-PRESSURE COMPRESSION ELEMENT IN A LAMINATED MANNER, AND A SUB-BEARING SUPPORTING A ROTATING SHAFT, AND WHEREIN EACH OF THE LOW-PRESSURE COMPRESSION ELEMENT AND THE HIGH-PRESSURE COMPRESSION ELEMENT COMPRISES A CYLINDRICAL-SHAPED CYLINDER, A CYLINDRICAL-SHAPED ROLLER REVOLVING ECCENTRICALLY ALONG AN INNER WALL OF THE CYLINDER, AND A VANE IN THE FORM OF A FLAT PLATE TO DIVIDE A SPACE DEFINED BY AN OUTER PERIPHERY OF THE ROLLER AND THE INNER WALL OF THE CYLINDER, AND AN ANGLE BETWEEN THE VANE OF THE LOW-PRESSURE COMPRESSION ELEMENT AND A POSITION, IN WHICH A CLEARANCE BETWEEN THE INNER WALL OF THE CYLINDER AND AN OUTER PERIPHERY OF THE ROLLER BECOMES MINIMUM, IS SET TO RANGE FROM 150° TO 210°.
