PURPOSE:To separate lubricating oil in discharging gas effectively by a method wherein a path, communicating a delivery chamber with a motor chamber formed above a motor, is extended to the vicinity of stator coil of the motor and is opened while a collision wall is provided below the opening. CONSTITUTION:The lubricating oil in refrigerant gas, compressed in a compression chamber 9, moves to a motor chamber 1b through a delivery chamber 10, paths 18a, 18b and a path guide 31. The discharging gas, containing oil guided by the path guide 31, collides against the collision wall 41 provided above the stator 3a of the motor and becomes horizontal flow along the upper surface 3g of the stator of motor 3. Accordingly, the refrigerant gas flows in the upper space 1b of the motor 3 together with the flow of oil, however, only the oil is dropped and the flow of refrigerant gas is elimiated in the notched paths 42a, 42b of outer periphery of the stator 3a for the motor 3.
