Patent ID: 6994078

Claim:
A separator for separating liquids in a fluid stream generated by blow-by gasses produced in a crankcase of an internal combustion engine, the fluid stream including both gasses and liquids, said separator comprising: an inlet in fluid connection with the engine for receiving the fluid stream and an outlet in fluid connection with the engine to return a gas stream to the engine; a fluid path fluidly connecting said inlet to said outlet; a containment vessel in fluid connection with said fluid path having a fluid containment region; a spiral fluid stream accelerator in said fluid path that extends about a spiral axis, said spiral accelerator accelerating said fluid stream radially outwardly from said spiral axis to at least partially separate the gasses from the liquids in the fluid stream; and, a deflector in said fluid path between said accelerator and said outlet to change the direction of said liquid to direct at least part of the liquids in the fluid stream into said fluid containment region and said gas stream to said outlet.
