rotary screw compressor with in-line oil separator

摘要

An oil separator (28) for use in a compressor for separating oil from refrigerant. The separator includes a discharge line (26) having an inner surface, a structure (28) in the discharge line forming an inlet (31) and an outlet (34) within the discharge line, wherein the outlet (34) has a wider diameter than the inlet (31); and a design for preventing oil from exiting the outlet and means for directing the oil out of the discharge line (26). In one embodiment, the structure (28) is a substantially circular wall (32), and wherein the design for preventing is the shape of the wall (32) and relative orientation of the wall to the discharge line (26). In one embodiment, the relative orientation is such that the discharge line (26) has a flow direction with a horizontal component of orientation and the wall (32) has a vertical component of orientation relative the horizontal component.
