<p>The present invention increases the compactness of an oil recycling mechanism that returns a lubricating oil isolated from a discharged refrigerant to an intake pressure region, and increases production characteristics. The oil recycling mechanism is configured containing: an oil isolating section (isolating chamber (104b2) and isolating pipe (130)) that isolates the oil from the discharged refrigerant; an oil storage chamber (132) that retains the isolated oil; an oil return pathway that interconnects the oil storage chamber (132) and an intake chamber (119); and an orifice (136) provided with a filter and disposed in the oil return pathway. The oil storage chamber (132) is caused to extend in the diametral direction of a compressor housing and has an open end at the outer surface of the housing. The open end is occluded by an occluding member (134). A partition wall (bulging section (132a)) that separates the oil storage chamber (132) and the intake chamber (119) is at a region to the inside of the aperture of the open end. The oil return pathway is formed in a linear shape in the partition wall, and the orifice (136) provided with the filter is housed and positioned therewithin.</p>
