A scroll compressor includes various features that promote a bifurcated flow pattern of gas through a compressor shell to reduce oil entrainment. After entering the shell, some gas travels upward, which reduces the volume of gas traveling downward toward an oil sump. To accomplish this, the compressor's motor can be surrounded by a sleeve having upper and lower apertures for directing the flow to the motor's upper and lower stator end turns. In some embodiments, a suction inlet is strategically positioned relative to two gas passageways that are between the stator and the compressor shell. The inlet's position is such that one passageway receives incoming gas and divides the flow in opposite directions: upward and downward. The other passageway only conveys the gas upward. In addition, a suction baffle, a diffuser, a streamlined counterweight and / or a suction line oil trap can also help promote gas / oil separation or minimize oil entrainment.

Manufacturing method enabling optimal volume oil-fill even where differing from bearing to bearing due to machining fluctuations in volume-production dynamic pressure bearings. In a first charging method, injection of oil is divided into two cycles. The first is carried out under reduced pressure, following which the pressure is raised a predetermined amount to force the oil into the bearing gap.
