ROTARY COMPRESSOR

摘要

In a rotary compressor, a second muffler (17A) has a cup shape, and is symmetrically arranged in a direction different by 90° from positions of first muffler discharge ports (16a, 16b) with a crankshaft at the center. The second muffler has half circular arc cut regions (n1, n2) from a second muffler crankshaft hole (17h) toward the external. Thus, the second muffler is provided with the discharge port structure capable of discharging a compressed gas so as not to disturb the flow of a lubricating oil that returns to an oil storing section along an inner wall surface of a casing.
