Abstract

A rotary compressor includes: a vertically-positioned airtight compressor housing, in an upper section of which a discharge unit of a refrigerant is provided and in a lower section of which an inlet unit of the refrigerant is provided and lubricant oil is stored; and a lubricating mechanism supplying lubricant oil stored in the lower section of the compressor housing to a sliding portion of a compressing unit through a vertical lubricating hole and a horizontal lubricating hole of a rotation shaft. The horizontal lubricating hole of the lubricating mechanism is formed between the same direction as an eccentric direction of an eccentric portion provided on the rotation shaft and causes an annular piston of the compressing unit making an orbital motion in a cylinder and a 80° phase shifted direction from the same direction as the eccentric direction in a direction opposite to a rotation direction of the rotation shaft.
