PURPOSE: A rotary compressor for preventing leakage of refrigerant is provided to reduce the leakage of the compressed refrigerant by increasing contact surface between the rolling piston and a vane. CONSTITUTION: A rotary compressor comprises a rolling piston(340), a vane(350), and a lubrication member(360). The rolling piston is combined in the crank shaft of the drive motor. The rolling piston has a sealing groove(341) formed in the outer circumference in the axial direction. The vane is combined in the sealing groove of the rolling piston to rotate. The vane divides the compression space of the cylinder along with the rolling piston into an intake chamber and an ejection chamber. The lubrication member is assembled between the rolling piston and the vane. |
