摘要
PURPOSE: A 2-stage rotary compressor is provided to reduce the vibration through the shape change of an eccentric part without the structure change of other parts of compressor assembly.;CONSTITUTION: A 2-stage rotary compressor comprises an airtight container, a rotary shaft(113), low pressure compression assembly, and high pressure compression assembly. The rotary shaft is installed in the airtight container and comprises a low-pressure eccentric part(113a) and a high-pressure eccentric part(113b), which are eccentric to the central axis. The low pressure compression assembly compresses the refrigerant with a roller rotated by the low-pressure eccentric part. The high pressure compression assembly compresses the refrigerant with a roller rotated by the high-pressure eccentric part. The size of the centrifugal force generated by the high-pressure eccentric part and a high pressure roller(133) is between 70%-100% of the size of the centrifugal force generated by the low-pressure eccentric part and a low pressure roller(123).;COPYRIGHT KIPO 2011
