A compressor for compressing a mixture gas including a mist of lubrication oil and a gas to be taken out of the compressor with a pressurized condition, comprising,
- a pair of compressing members movable with respect to each other so that the mixture gas is compressed therebetween,
- a motor for driving at least one of the compressing members to generate a relative movement between the compressing members for compressing the mixture gas, and
- an oil-mist separator for separating the mist of lubrication oil from the mixture gas to collect the lubrication oil,
- wherein the oil-mist separator includes an inner surface forming a chamber for receiving the mixture gas, an inlet passage for directing a flow axis of the mixture gas when the mixture gas reaches the chamber, and a discharge passage includes a discharge port opening in the chamber to discharge the gas from the chamber through the discharge port.
