Abstract
A rotary compressor for use with refrigerating apparatuses such as freezing refrigerators, freezers, showcases for household or commercial use incorporates a mechanism in a compressor unit. When a space to be freezed is freezed in a on-off operation mode, the mechanism prevents a large amount of high temperature refrigerant gas in a closed casing of the compressor from being discharged to an evaporator during the suspension of the operation of the compressor.
