Rotary compressor and the refrigeration cycle apparatus

The present invention discloses a rotary compressor and a refrigerating cycle apparatus. Rotary compressor comprising: a built-in lubricating oil sealed in the sealed interior of the housing, the inner housing having an electric motor and the rotary type compression mechanism, and the internal pressure of the suction pressure of the compression mechanism housing considerably. The compression mechanism includes a main bearing, auxiliary bearing, the main bearing and the sub-bearing is provided in at least one of the exhaust muffler. The exhaust muffler vane chamber through the refrigerant, provided from the compression mechanism exhaust pipe. The rotary compressor of embodiment of the present invention, effective lubrication can slide the sliding surface, the oil can be controlled to ensure the reliability of the entire compressor vane, additional lubrication is possible to prevent problems caused by reduced compressor efficiency.
