Abstract

DISCLOSED IS AN ENCLOSED COMPRESSOR IN WHICH FORCE EXERTED ON THE ROTATING SHAFT (3) IS REDUCED, UNBALANCED FORCE IS COMPENSATED FOR, AND VIBRATIONS ARE REDUCED. A COMPRESSING MECHANISM (2) HAS AN ECCENTRIC PORTION (7) THAT PRODUCES A ROTARY MOTION. A LOWER BALANCE WEIGHT (12) IS PROVIDED ON THE END FACE OF THE ROTOR (5) AT A POSITION OPPOSITE TO THE ECCENTRIC PORTION (7). PROVIDED ON THE OTHER END FACE OF THE ROTOR (5) IS AT LEAST ONE OF I) AN UPPER BALANCE WEIGHT (11) PROVIDED AT A POSITION SIMILAR TO THAT OF THE ECCENTRIC PORTION (7) AND II) A HOLE (16, 17) IN THE DIRECTION ALONG THE ROTATING SHAFT (3) PROVIDED AT A POSITION OPPOSITE TO THE ECCENTRIC PORTION (7). THE LOWER BALANCE WEIGHT (12) HAS A, SPACER (14) INTERPOSED BETWEEN THE LOWER BALANCE WEIGHT (12) AND THE END FACE OF THE ROTOR (5), OR IS HIGHER THAN ANOTHER WEIGHT (12A) PROVIDED ON THE END FACE OF THE ROTOR (5). THIS MAKES THE POSITION OF THE CENTER OF GRAVITY OF THE LOWER BALANCE WEIGHT (12) IN THE DIRECTION ALONG THE ROTATING SHAFT (3) IN PROXIMITY TO THE COMPRESSING MECHANISM (2).FIGURE 3
