Abstract
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.
