Air/oil coalescer with an improved centrifugally assisted drainage

摘要

A coalescing filter assembly and a corresponding cover are disclosed. The assembly is mounted to a rotating component substantially within an engine crankcase, and is synchronously rotated with the rotating component about an axis. Vent gas of the engine crankcase is in fluid communication with the coalescing filter assembly through one or more inlet ports. The coalescing filter assembly is preferably mounted to a gear and includes a filter located within a cavity formed between a first housing element and a second housing element. The coalescing filter assembly components are substantially concentric with the axis about which the gear rotates, and the assembly and gear synchronously rotate with one another. The cover preferably includes a diaphragm to control the rate of flow of vent gas from the engine crankcase through the coalescing filter assembly into the outlet conduit of the cover.
