TH86260B - Multi-cylinder rotary compressors, compression systems and freezing equipment that use such compression systems - Google Patents

Abstract

In a multi-cylinder rotary compressor that has been assembled to be used by Push only the first impeller to the first roller by the spring assembly to change the first working type, which The first and second rotary compression parts produce both the compression and second working tasks. Only one rotary recording will generate a recording task, for the purpose of reducing sound reproduction. Collision due to collision of the second impeller with the second roller at a time when the first operation type is Change to a second working design And the pressure in the second impeller back pressure chamber is released On the chamber side, low pressure in the second cylinder in case the first operating type is changed to the second operating type.

Claims (1)

1. The multi-cylinder rotary compressor consists of a sealed container in which the parts Drive and the first and second rotational compression parts driven by the drive part's rotating shaft are inserted. Where the first and second rotary compression parts consist of first and second cylinders, first and second rollers forced with eccentric sections formed on the rotating shaft to rotate eccentrically in the cylinder cylinder respectively and the impeller. First and second, which are pushed on the first and second rollers to divide each cylinder. Pumped is the low pressure chamber side and the high pressure ch
