摘要： A compressor compresses gas containing misted oil. The compressor has a drive plate located in a crank chamber and mounted on a drive shaft and a piston operably coupled to the drive plate and located in a cylinder bore. The drive plate converts rotation of the drive shaft to reciprocating movement of the piston in the cylinder bore to vary the capacity of the cylinder bore. The piston compresses gas supplied to the cylinder bore and discharges the compressed gas from the compressor by way of a discharge chamber and a discharge passage. An oil separating mechanism is disposed midway in the discharge passage to separate the oil from the gas flowing in the discharge passage. A storing chamber is defined in the lower portion of the separating mechanism to store the oil separated from the gas. A supplying passage connects the storing chamber with the crank chamber to supply the oil to the crank chamber from the storing chamber. A supplying valve is disposed midway in the supplying passage. The supplying valve opens the supplying passage to supply the oil to the crank chamber from the storing chamber when the compressor is stopped.
