【0026】更に、バランサを複数並べて用いた場合では(バランサ50B、50C参照)では、部分50X、 Furthermore, in the case of using by arranging a plurality of balancer (balancer 50B, 50C refer), the portion 50X,
50Y、50Zの面積を変更することにより、微妙なバランス調整が可能となる。 50Y, by changing the area of ​​50Z, it is possible to fine balancing.

【0027】尚、圧縮機の運転時においては、プレート51は、冷媒ガス中のミスト状の潤滑オイルを、遠心力により放射状に分散させて周囲に付着させることにより、冷媒ガスとミスト状の潤滑オイルとの分離を行う働きがある。 [0027] Incidentally, during the operation of the compressor, the plate 51, the mist-like lubricating oil in the refrigerant gas, by adhering to the periphery dispersed radially by centrifugal force, the refrigerant gas and mist of lubricant there is work to carry out the separation of the oil.

【0028】次に、第2実施例について説明する。 Next, a second embodiment will be described. 第1 First
実施例と異る部分は、バランサを複数枚重ねた点である。 Example and yl moiety is that stacked plurality of balancers.

【0029】バランサ50Dは、プレート50Fと50 [0029] The balancer 50D, the plate 50F and 50
Gとで構成されており、バランサEはバランサ50Gとバランサ(部分)50Yとで構成されている。 G and is composed of, balancer E is composed of a balancer 50G and the balancer (partial) 50Y.

【0030】このように、バランサを複数重ねた場合は、回転子の部分で重量バランスを大きく偏心させることによって、回転圧縮要素10と結合させた状態の際の全体の回転バランスをとることができる等の効果がある。 [0030] Thus, when the stacked plurality of balancers, by largely eccentric weight balance in the portion of the rotor can take the rotational balance of the whole during a state of being coupled with the rotary compression elements 10 there is an effect and the like.

【0031】 [0031]

【発明の効果】以上説明したように、請求項1に記載の発明によれば、回転子では、そのバランサは板材で形成され、プレートと一体に回転子に取付けられているので、プレートを別途軸受けなどに取付ける必要がなく、 As described in the foregoing, according to the invention described in claim 1, in the rotor, the balancer is formed of a plate material, so attached to the rotor to the plate and integral, separately plate there is no need to attach to such as bearings,
製造コストを低下させることができる。 It is possible to reduce the manufacturing cost.

【0032】また、請求項2に記載した発明によれば、 [0032] According to the invention described in claim 2,
前記バランサは板材を打ち抜いて形成されたものであるので、バランサの製造も容易で、且つ金型などの高価なものを使用する必要もこともなく、安価な回転子を提供することができる。 The balancer so and is formed by punching a plate material, the manufacture of the balancer is easy, and also there is no need to use expensive, such as mold, it is possible to provide an inexpensive rotor.
