PROBLEM TO BE SOLVED: To handle refrigerant 27 and oil 6 by substantially restraining them so as to discharge gas, which has been sufficiently separated into gas and liquid, from an external discharge pipe 39. SOLUTION: The refrigerant gas 27 containing oil 6 is discharged from a discharge port 18. The refrigerant gas passes through a stator passage 37 after passing a rotor passage 36, and flows out to a stator upper chamber 38 of an outer circumference of a communication passage 34. By providing mesh 100 to a lower part of a stator 3b of a sealed vessel 1, the refrigerant gas 27 containing oil 6 is collided with the mesh 100, and the oil 6 is adhered to the mesh 100. Therefore, only the refrigerant gas 27 passes through the stator passage 37 and flows out to the stator upper chamber 38 of the outer circumference of the communication passage 34, and gas-liquid separation of the refrigerant is efficiently performed.
