Abstract
The invention discloses a rotating compressor which comprises a housing and an upper cover, wherein the upper cover is in seal weld with an exhaust pipe which communicates the inner part of the housing with the outside word and is used for discharging refrigerant. The rotating compressor is characterized in that the exhaust pipe is internally provided with an oil separating structure capable of changing the flow direction of refrigerant after being collided with the refrigerant. For the rotating compressor, the exhaust pipe is additively provided with the oil separating structure, so that the refrigerant airflow (including refrigerating machine oil) enters from an air inlet, and is contacted and collided with the oil separating structure, so that the lubricating oil (the refrigerating machine oil) is gathered into large oil drops, the large oil drops are separated out of the refrigerant and reflow into the compressor, and the rest of refrigerant airflow is discharged out of a sealed space of the housing. With the rotating compressor, the refrigerating machine oil is separated from the refrigerant airflow, so that the running reliability of the compressor can be effectively guaranteed, and the performance of a heating and ventilating system can be improved.
