Abstract: The present invention includes: an electric component; a compression component driven by the electric component; and a sealed container accommodating the electric component and the compression component. The compression component includes: a shaft part rotated by the electric component; and a bearing part slidingly contacting the shaft part. A film having hardness equal to or more than hardness of a sliding surface of the bearing part is provided on a sliding surface of the shaft part. The sliding surface of the bearing part includes a curved-surface portion having an inner diameter that continuously increases, or the sliding surface of the shaft part includes a curved-surface portion having an outer diameter that continuously decreases.

Abstract: The present invention includes: an electric component; a compression component driven by the electric component to compress a refrigerant; and a sealed container accommodating the electric component and the compression component. The compression component includes: a shaft part rotated by the electric component; and a bearing part slidingly contacting the shaft part such that the shaft part is rotatable. A film having hardness equal to or more than hardness of a sliding surface of the bearing part is provided on a sliding surface of the shaft part. The sliding surface of the bearing part includes a curved-surface portion having an inner diameter that continuously increases in a curved shape toward an end of the bearing part in a center axis direction of the bearing part, or the sliding surface of the shaft part includes a curved-surface portion having an outer diameter that continuously decreases in a curved shape toward an end of the shaft part in a center axis direction of the shaft part.

Abstract: A stator of an outer-rotor type motor is fixed to a stator fixing member, and the stator fixing member is fixed to a member (cylinder block) of a compression element, which has a main bearing. Further, an auxiliary bearing is configured to be separate from the stator fixing member and is fixed to the stator fixing member. In this manner, it is possible to fix the stator fixing member to the member of the compression element in a state in which an even clearance is formed between an inner circumference of a rotor and an outer circumference of the stator, and it is possible to fix the auxiliary bearing to the stator fixing member in a state in which the auxiliary bearing is reliably coaxial to the main bearing. Therefore, it is possible to narrow the clearance between the inner circumference of the rotor and the outer circumference of the stator such that it is possible to achieve high efficiency of the motor.

Abstract: In a sealed compressor (100) of the present invention, a suction muffler (160) includes a communication pipe (162) coupled to a suction hole (151a) of a valve plate (151). The communication pipe (162) extends upward from the suction muffler (160) toward the other end of a cylinder (133), and is provided at an upper end thereof with a communication pipe exit section (162a) which is in communication with the suction hole (151a). The cylinder head (152) is formed on a lower portion with a recess (152d) accommodating the communication pipe exit section (162a) therein. A gas inflow space (152b) in the interior of the sealed container is formed between the communication pipe exit section (162) and a recess (152d). The gas inflow space (152b) in the interior of the sealed container is a space which is in communication with a sealed space inside of the sealed container (101).
