Patent ID: 7311501

Claim:
A scroll compressor for compressing a gas, wherein the scroll compressor is lubricated by a lubricant, the scroll compressor comprising: a compressor shell defining a suction inlet; a first scroll member disposed inside the compressor shell and having a first scroll wrap; a second scroll member disposed inside the compressor shell and having a second scroll wrap interleaved with the first scroll wrap; a stator for creating a magnetic field, the stator includes an upper end turns, a lower end turns, and a stator core interposed therebetween, the stator and compressor shell define therebetween a first gas passageway and a second gas passageway, wherein the first gas passageway conveys the gas in both upward and downward directions while the second gas passageway conveys the gas substantially only in an upward direction; a rotor disposed within the stator to define a rotor gap therebetween, wherein the rotor rotates in response to the magnetic field and is coupled to the second scroll member to drive the second scroll member in an orbital motion relative to the first scroll member, thereby compressing the gas between the first scroll wrap and the second scroll wrap; and an oil trap that includes a suction tube leading to the suction inlet, an orifice plate extending radially inward from the suction tube for restricting gas flow therethrough, and a flow divider extending from the orifice plate in an upstream direction through the suction tube, wherein the orifice plate defines an opening through which substantially all of the gas and the lubricant within the suction tube eventually passes therethrough, wherein the location of the opening is biased toward a lower portion of the suction tube.
