Abstract

IN A ROTARY COMPRESSOR (1; 101; 201) INCLUDING FIRST (30; 130; 250) AND SECOND CYLINDERS (50; 50; 230) ALIGNED IN THE AXIAL DIRECTION OF A DRIVE SHAFT (3B), A SUCTION PASSAGE IS FORMED TO SUPPLY REFRIGERANT SUPPLIED FROM AN EXTERNAL DEVICE VIA A SUCTION PIPE (6) TO EACH COMPRESSION CHAMBER (31; 31; 51). THE SURFACE AREA OF A REGION FACING THE SUCTION PASSAGE IN THE SECOND CYLINDER IS SMALLER THAN THE SURFACE AREA OF A REGION FACING THE SUCTION PASSAGE IN THE FIRST CYLINDER. A DIFFERENCE BETWEEN THE HEIGHT (A3; A3; A1) OF THE SECOND CYLINDER IN THE AXIAL DIRECTION AND THE HEIGHT (A2; A2; A4) OF A PISTON PROVIDED IN THE COMPRESSION CHAMBER OF THE SECOND CYLINDER IS SMALLER THAN A DIFFERENCE BETWEEN THE HEIGHT (A1; A1; A3) OF THE FIRST CYLINDER IN THE AXIAL DIRECTION AND THE HEIGHT IN THE AXIAL DIRECTION OF A PISTON (52; 52; 32) PROVIDED IN THE COMPRESSION CHAMBER OF THE FIRST CYLINDER (A3-A4<AL-A2). WITH THIS ARRANGEMENT, DOWNSIZING OF THE COMPRESSOR AND SUPPRESSION OF DECREASE IN COMPRESSOR EFFICIENCY ARE BOTH ACHIEVED. (FIGURE 3)
