20140033922 | Methods and Assemblies for Separating Liquid from a Gas-Liquid Stream - 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. | 02-06-2014 |
20150027422 | Crankcase Ventilation Inside-Out Flow Rotating Coalescer - 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. | 01-29-2015 |
