COMPRESSOR

摘要

A compressor comprises a housing and a cylinder oil separating device installed in an oil separation room. The housing comprises a discharge room; an oil separation room; a distribution path; and an output port. The discharge room discharges compressed cooling gas. The distribution path connects the discharge room and the oil separation room. The output port delivers the cooling gas of the oil separation room to the outside of the housing. The oil separating device comprises a large-diameter unit, a small-diameter unit, and an intermediate-diameter unit which is formed between the large-diameter unit and the small-diameter unit and which is tapered toward the small-diameter unit. A plurality of small holes is formed around the circumference unit of the small-diameter unit of the oil separating device. The distribution path is toward the small-diameter unit of the oil separating device in order for the cooling gas to be around the small-diameter unit. The cooling gas in which lubricant oil is separated is delivered to the oil separating device through the small holes.
