Abstract
A scroll compressor includes an oil separation region generally formed between the motor housing and upper bearing member. A long labyrinth channel is provided with the suction refrigerant gas flow path being redirected to facilitate coalescing of oil mist droplets out of the gas stream. An integral deflector plate can be provided on the upper bearing member to interrupt flow and facilitate coalescing of oil. Additionally, offset arrangements between motor housing outlet ports and through ports through the bearing member are provided to facilitate redirection of the refrigerant flow that can further achieve oil separation.
