法による回転変動の低減が必要である。Structure of the conventional example and its problems As shown in Fig. 1, a conventional rotary compressor has a structure in which a compression mechanism part 2 and an electric motor part 3 are built inside a sealed container 1. . Here, the rotor 4 of the electric motor section 3 is integrated with the crankshaft 5 and piston 6 of the compression mechanism section 2 to perform rotational movement and compress the refrigerant. In a rotating system consisting of a piston 6, since the eccentric portion 7 of the crankshaft 5 and the piston 6 are eccentric with respect to the rotation center 8 of the rotor 4 and crankshaft 5, vibrations due to rotation become large. Install balance ways 1 to 9 and lower balance eight 10 to absorb vibrations caused by eccentricity, but they have no significant effect on reducing rotational fluctuations when something negative happens, and other methods are not effective. It is necessary to reduce rotational fluctuations due to

This is a compression mechanism that compresses refrigerant using axial force. 16 is the bolt 17 and the rotor 1 is attached to the bottom of the rotor 13.
It is a flat plate with an appropriate weight fixed concentrically with the rotor 13, and is formed to have a larger diameter than the rotor 13.

ることができる。When the compressor is operated with the above configuration, the inertia t-men 1~ by the rotor 13, crankshaft 14, and flat plate 16 that make up the rotating system are replaced by the conventional rotating system consisting of the rotor and crankshaft. Since the moment of inertia due to the flat plate 1G increases, the rotation fluctuation of the compressor can be reduced.
