Claims

[Scope of utility model registration request]

The oil stored in the sealed case is pumped up by the centrifugal pump action of the rotary shaft, and is pumped up to the compressor section through an oil suction hole drilled in the axial direction of the rotary shaft and an oil port provided in communication with the oil suction hole. In a rotary compressor configured to supply oil to the sliding surface of the rotary shaft, the eccentric portion of the rotating shaft has both ends opened into a space surrounded by the eccentric portion, the inner circumferential surface of the roller, and the upper and lower frames, and A rotary compressor, characterized in that a vertical hole is provided substantially parallel to the oil absorption hole, and a horizontal hole is provided that communicates the vertical hole and the oil absorption hole and opens one end to the outer peripheral surface of the eccentric part. Refueling mechanism.
