摘要： A closed crankcase emission control assembly for an internal combustion engine includes a filter assembly comprising a housing and a replaceable filter element. The filter element includes a ring of filter media; a first annular end cap sealed to one end of the media ring; a second end cap sealed to another end of the media ring; a cup-shaped valve pan fixed to the second end cap and which together therewith defines a sump container; and an opening with a lip seal in the valve pan which closely receives a standpipe from the housing to allow continuous drainage of oil collected by the filter element. The filter housing includes 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.

摘要： A closed crankcase emission control system for an internal combustion engine includes a replaceable filter element having a ring of filter media; a first end cap at one end of the media ring; a sump container defined by a second end cap at 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 to flow out of the sump container during engine idle or shut-down. A shut off valve is provided to prevent oil from passing through the emission control system to the engine. The shut off valve comprises a cylindrical float member with a supporting body and a seal, where the body includes a guide member. The float member could also be a ball valve. The float member floats with the level of oil in the housing, and can fluidly seal against a valve seat to prevent oil passing to the engine. The shut off valve can be incorporated into the filter element, into a central support tube of the housing, or into the inlet or outlet fittings for the housing. Supporting structure is provided to maintain the float member in a proper orientation. A pressure relief valve can also be provided upstream from the shut-off valve to relieve system pressure when the shut-off valve is closed.

摘要： A crankcase breather for an internal combustion engine has a housing including inlet ports which receive crankcase emissions from the engine, and an outlet port which directs oil-free gases back to the engine. A pair of filter elements are supported in the housing in adjacent relation. One filter element is a course filter to remove larger particulate in the emissions. The other filter element is a finer filter to remove smaller particulate, and to coalesce oil. A sump channel under the elements collects oil coalescing on the elements, and a drain opening in the channel to returns the oil to the engine. A second sump collects oil coalescing on the downstream surface of the second filter. An outlet port with a check valve in the second sump prevents oil being drawn into the breather on the clean side of the elements, but allows collected oil to drain back to the engine.

摘要： A fuel filter assembly incorporates a modular drain bowl which may be removably mounted at the lower end of the disposable filter cartridge. An anchor insert is disposed interiorly at the lower portion of the cartridge sump for anchoring a fastener to attach the drain bowl. The insert also is specially configured to form outlet passages which facilitate the flow of water from the sump to the drain bowl.
