Seal mechanism protector for compressors
A compressor including a compressing mechanism accommodated in a housing. The mechanism draws refrigerant from an intake chamber into a compression chamber and discharges the refrigerant from the compression chamber to the discharge chamber. A seal device prevents leakage of refrigerant from the internal space to the atmosphere between the drive shaft and the housing. An isolation chamber, which is separately formed in the housing, accommodates the seal device. A pressure reducing passage reduces the pressure of the isolation chamber to reduce the pressure difference applied to the seal device.
