| 摘要 |
The invention concerns a parallel- and internal-axis rotary-piston compressor having a driven outer rotor (12) with a compressor chamber (17) in which an inner rotor (20) is rotatably mounted. The inner rotor (20) is hollow and made of light alloy, and is fitted on a shaft (21). Accurate balancing of the inner rotor is achieved by means of heavy-metal pins (42, 43) which extend over the whole length of the inner rotor (20). The heavy-metal pin (43) acts at the same time as a lock preventing the inner rotor (20) from rotating on the shaft (21) if these parts are not integral with each other. |
