Disclosed is an exhaust valve (A,B,C,D,E), comprising a valve body (), wherein the first end of the valve body is provided with a fluid inlet (); the sidewall of the valve body is provided with at least one fluid outlet () in fluid communication with the fluid inlet () and a valve flap () for opening or closing the fluid outlet; and the axis direction of the fluid outlet () is inclined relative to that of the fluid inlet (). Further disclosed is a compressor comprising the above-mentioned exhaust valve. The exhaust valve has a relatively low fluid resistance, and is able to significantly reduce the pressure drop in the compressor due to the exhaust valve, so that the operating efficiency of the compressor is increased.

A rotary compressor, comprising: a housing, comprising a lubricant oil storage part for containing lubricating oil; a compression mechanism disposed in the housing; a driving mechanism driving the compression mechanism, the driving mechanism comprising a rotation shaft, through-holes extending along the axial direction of the rotating shaft are disposed inside the rotating shaft, and the rotation shaft is in fluid connection with the lubricating oil storage part via the through-holes; and an oil level sensor in fluid connection with the through-holes inside the rotation shaft via a pressurized collection channel. Also disclosed is a rotation mechanism, comprising an oil level sensor in fluid connection with the through-holes inside the rotation shaft via the pressurized collection channel. Accurate and reliable detection of the lubricating oil in a compressor can be done using the pressurized collection channel and the oil level sensor, thus greatly saving cost and improving compressor reliability.
