Abstract

PURPOSE:To reduce the sliding friction loss by arranging a motor rotor apart downward from the center axis of a stator so that the tensile force by the magnetic force of the permanent magnet of the rotor is applied to the center of the stator. CONSTITUTION:A rotary compressor is constituted of an upper bearing 1, a piston 2, a cylinder 3, and a lower bearing 4. A motor rotor 5 rotated integrally with the cylinder 3, a motor stator 9, and a refrigerant intake guide path 6 are provided. Since the motor rotor 5 is arranged apart downward from the center axis of the stator 9, the tensile force by the magnetic force of the permanent magnet of the rotor 5 is applied to the center of the stator 9. The force applied on the end face of the piston by the weight of the rotating section is thereby reduced, and the sliding friction loss can be reduced.
