因してサイクル動作において力効率および冷却効率の損
失がある。The airtight rotary motor compressor feeds the suction gas directly to the compressor and then brings the airtight casing of the compressor to the discharge pressure. Doing this will minimize the pressure loss on the suction side of the compressor and improve the efficiency of the compressor. That is, since a large mouth valve is not required, the pressure loss of the rotary compressor is small, and there is no loss due to excessive heating of the suction gas. A further structural advantage is that the gas-tight casing also serves to connect the compressor block to the stator, resulting in material savings, since suction is applied directly to the compressor block without intervening elastic devices. However, this type of hermetic rotary compressor has several drawbacks that cannot be ignored. That is, there is a loss of power efficiency and cooling efficiency in cycling due to absorption of oil into the cooling gas.

互換性は寸法上の問題ではなく、回転コンプレッサの性
能を維持するのに不可避の振動に関する問題である。Furthermore, since there is no elastic device between the compressor and the hermetic casing, vibrations are transmitted to the outside of the compressor, increasing the noise of the cooling device. Furthermore, rotary compressors are difficult to replace with conventional reciprocating compressors. This incompatibility is not a dimensional problem, but rather a vibration problem that is unavoidable in maintaining rotary compressor performance.

従って本発明の目的は、上述の欠点を解決する気密回転
モータコンプレッサを得るにある。SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a hermetic rotary motor compressor which overcomes the above-mentioned drawbacks.
