SUCTION DUCT AND SCROLL COMPRESSOR INCORPORATING SAME

摘要

A scroll compressor and assembly includes a suction duct to direct refrigerant from the housing inlet to a location upstream of a motor. Additionally, the suction duct includes drain ports that act to drain oil received in the suction duct into the oil sump. This can be used for filling and charging the oil sump with oil initially by using the common refrigerant inlet port through the housing and also acts to collect coalesced oil from oil mist generated by operation of the scroll compressor in a refrigeration system and likewise drain the lubricant oil into the lubricant sump.
