<P>PROBLEM TO BE SOLVED: To downsize an oil recycling mechanism for returning lubricating oil isolated from a discharged refrigerant to an intake pressure region, and to improve productivity. <P>SOLUTION: The oil recycling mechanism is configured to include: an oil isolation unit (isolation chamber 104b2 and isolation pipe 130) that isolates the oil from the discharged refrigerant; an oil storage chamber 132 storing the isolated oil; an oil return pathway communicating the oil storage chamber 132 and an intake chamber 119; and an orifice 136 with a filter disposed in the oil return pathway. The oil storage chamber 132 is extended in the radial direction of a compressor housing and has an open end on the outer surface of the housing. The open end is sealed by a sealing member 134. A partition wall (bulging part 132a) that partitions the oil storage chamber 132 from the intake chamber 119 is disposed in a region inside the aperture of the open end. The oil return pathway is formed in a linear shape in the partition wall, in which the orifice 136 with the filter is housed and positioned. <P>COPYRIGHT: (C)2012,JPO&INPIT |
