Abstract: An internal combustion engine crankcase ventilation rotating coalescer includes an annual rotating coalescing filter element, an inlet port supplying blow by gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering clean separated, air from the exterior of the rotating element. The direction of flow by gas inside-out, radially, outwardly from the hollow interior to the exterior.

Abstract: A two stage gas-liquid separator assembly includes a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A first plenum chamber includes a pre-separator that causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the first plenum chamber. A second plenum chamber includes a main separator downstream of the pre-separator that further causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the second plenum chamber. A first drain port drains liquid from the lower portion of the first plenum chamber and a second drain port drains liquid from the lower portion of the second plenum chamber. Liquid drains from the first and second plenum chambers regardless of a pressure difference between a pressure in the first plenum chamber and a pressure in the second plenum chamber.

Abstract translation: 两级气液分离器组件包括具有用于接收气液流的入口和用于排出气流的出口的壳体。 第一增压室包括预分离器，其使液体与气 - 液流分离并排放到第一增压室的下部。 第二增压室包括在预分离器下游的主分离器，其进一步使液体与气 - 液流分离并排放到第二增压室的下部。 第一排水口从第一增压室的下部排出液体，第二排出口从第二增压室的下部排出液体。 不管第一增压室中的压力和第二增压室中的压力之间的压力差如何，来自第一和第二增压室的液体排出。
