Filter assembly with sump and check valve |
摘要 |
A closed crankcase emission control assembly for an internal combustion engine includes a replaceable filter element having a ring of filter media; a first annular end cap sealed to one end of the media ring; a sump container defined by a second annular end cap sealed to the other end of the media ring and a cup-shaped valve pan fixed to the second end cap; and a check valve in the valve pan to block blow-by gas flow directly into the filter element during engine operation, and to allow collected oil flow out of the sump container during engine idle or shut-down. The filter element of the present invention is located in a filter housing including an inlet port to receive blow-by gasses from the engine crankcase, and an outlet port to provide the substantially oil and particulate free gasses to an induction system (e.g. a turbocharger) and back to the engine crankcase. A pressure control assembly can be provided with the emission control assembly to maintain acceptable levels of crankcase pressure. |
