Abstract: A reciprocating type compressor includes a crank shaft that is coupled to a rotor of a motor to transfer a rotational force, a piston that compresses a refrigerant while linearly moving within a cylinder of a compression portion, a connecting rod that connects the crank shaft to the piston to convert a rotational force of the crank shaft into a linear motion of the piston, and a cylinder boss integral body in which the cylinder and a boss that encloses the crank shaft are integrally formed at right angles to each other.

Abstract: A compressor according to the present disclosure may include a bearing member located out of a range in an axial direction of a rotor. Accordingly, the bearing member and the rotor cannot overlap each other so as to reduce a bearing area. This may result in reducing a frictional loss of the compressor and ensuring a press-fit length of the rotor, so as to prevent interference between the rotor and a stator. Also, an area of an oil passage can be increased without an increase in the frictional loss, resulting in an increase in an amount of oil supplied.
Abstract translation: 根据本公开的压缩机可以包括位于转子的轴向范围之外的轴承构件。 因此，轴承构件和转子不能相互重叠，以减小承载面积。 这可能导致减小压缩机的摩擦损失并确保转子的压入长度，以防止转子和定子之间的干扰。 此外，可以增加油路的面积而不增加摩擦损失，导致供油量的增加。

Abstract: A compressor includes a casing, a motor, a cylinder block including a cylinder, and a piston. The motor include a stator and a rotor located outside the stator, a rotary shaft coupled to the rotor, and a rotor frame that accommodates the rotor and the rotary shaft and that is configured to rotate together with the rotor and transmit rotational force of the rotor to the rotary shaft. The rotary shaft includes an eccentric part configured to rotate based on the rotational force of the rotor and located at a position offset from a rotational axis of the rotary shaft. The piston is coupled to the rotary shaft and configured to reciprocate in the cylinder based on rotation of the eccentric part. The rotor frame has a mass distribution configured to compensate an unbalance force generated by movement of at least one of the piston or the eccentric part.
