Abstract:
1. An internal combustion engine crankcase ventilation rotating coalescer separating air from oil in blowby gas from a crankcase, comprising: a coalescing filter assembly comprising: wherein direction of blowby gas flow is inside-out, namely radially outwardly from said hollow interior to said exterior; wherein oil in said blowby gas is forced radially outwardly from said inner periphery by centrifugal force caused by rotation of said coalescing filter element, to reduce clogging of said coalescing filter element otherwise caused by oil sitting on said inner periphery, and to open more area of said coalescing filter element to flow-through, whereby to reduce restriction and pressure-drop; and wherein said centrifugal force caused by rotation of said coalescing filter element pumps said blowby gas from said crankcase to said hollow interior.
