The oil-mixed gas refrigerant discharged into the discharge hole (3
The muffler (5) is formed at a displaced position with respect to the muffler (5).
) is advected to the recess (52) side of the recess (52), and flows from the outlet (54) provided in the side wall (52a) of the recess (52) to the recess (52).
2) and the oil separation chamber (61) formed between the cover (6)
In other words, the gas refrigerant discharged from the discharge hole (35) is guided to the muffler ( 5) The oil is guided from inside to the oil separation chamber (61) while being rectified, and comes into contact with the mesh material (7) in the oil separation chamber (6d) in a rectified state. Therefore, the oil separation chamber (
The discharged gas refrigerant guided to the mesh material (61)
7), the gas refrigerant and oil are reliably separated, and the gas refrigerant from which the oil has been removed is transferred to the cover (6).
The gas is discharged from the gas outlet (9) through the inside of the casing (1) to the outside, while the oil is collected from the oil discharge part (8) to the bottom oil sump of the casing (1). This will reliably prevent the oil level from dropping in the reservoir. In addition, since the gas refrigerant discharged from the discharge hole (35) passes through the interior of the muffler (5) and cover (6), a double muffler effect is obtained, resulting in an excellent noise reduction effect. , driving noise is reduced.

き、分離効果をよりを効に達成できるのである。The gas refrigerant from which oil has been removed is discharged from the gas outlet (9) into the lower space of the motor (2), passes through the inside of the casing (1), and passes through the discharge pipe (12).
), and on the other hand, the separated oil is discharged from the oil discharge part (8) to the casing (1).
) is collected into the bottom oil sump (1a) of the oil sump (1a), and a drop in the oil level in the oil sump (1a) is reliably prevented, and oil supply by the oil pump (42) is performed satisfactorily. Furthermore, the oil mixed in the discharged gas refrigerant can be reliably separated without providing an oil separation plate or the like on the upper side of the rotor (22) in the motor (2), and even when used together with the separation plate, it is possible to separate the oil on a large scale. Since there is no need to do so, an oil separation plate is installed.
Compared to the case where separation is performed only by the separation plate, energy loss is not caused, and furthermore, the gas refrigerant discharged from the discharge hole (35) is distributed between the muffler (5) and the cover (6). Because it passes through the interior, a double muffler effect is achieved, resulting in excellent noise reduction and reducing operating noise. Furthermore, in a normal hermetic compressor,
The recess (52) is formed in the muffler (5) in order to securely fix the muffler (5) to the front head (32) side.
52) to form the oil separation chamber (61), the space of the muffler (5) can be used effectively, and the separation effect can be more effectively achieved.
