Abstract

A compressor exhaust structure includes a machine body, an exhaust bearing seat provided at an exhaust end of the machine body and an oil separating barrel covering the exhaust bearing seat, the exhaust bearing seat is provided with a first exhaust chamber, the machine body is provided with a second exhaust chamber, a third exhaust chamber is formed between the exhaust bearing seat and an inner wall of the oil separating barrel, the first exhaust chamber is in fluid communication with the second exhaust chamber, the second exhaust chamber is in fluid communication with the third exhaust chamber, and the third exhaust chamber is in fluid communication with a discharge port of the oil separating barrel. The compressor exhaust structure increases the flow path of the gas flow, facilitates the insulation of gas flow noise and reduces gas flow pulsation.
