Variable capacity type rotary compressor

摘要

A variable capacity type rotary compressor, in which a refrigerant sucked in via one suction pipe can be alternately sucked into each compression space via a communication passage between cylinders so as to reduce a number of components and a number of assembly processes, thereby reducing fabrication costs. A refrigerant within an idling cylinder is prevented from flowing back into another cylinder so as to improve performance of the compressor. A welding space can be ensured when connecting connection pipes so as to realize a welding automation, thereby further reducing the fabrication cost, and a mode switching valve is stably fixed to an appropriate position so as to attenuate noise due to vibration of compressor.
