AIR/OIL SEPARATOR ASSEMBLIES; COMPONENTS; AND METHODS

摘要

According to the present disclosure, arrangements, systems, components, features and methods for separating hydrophobic fluid such as oil entrained as aerosols from gas streams, such as crankcase ventilation gas streams are described. The components specifically described include a filter cartridge with preferred features for interaction with a filter housing, and a filter housing with preferred features for convenient installation. Methods of assembly and use are also characterized

主权项

1. A filter cartridge for use in gas/liquid separation; the filter cartridge comprising:
(a) an extension of filter media surrounding and defining an open filter interior; (b) first and second end pieces;
(i) the media being positioned between the first and second end pieces;(ii) the first end piece having a central flow aperture therethrough in gas flow communication with the open filter interior;(iii) the first end piece includes a perimeter rim having a portion projecting at least 3 mm toward the second end piece while completely surrounding the media; and,(iv) the second end piece has a closed external receiver therein projecting into the open filter and toward the first end piece a distance of at least 7 mm from an end of the media adjacent the second end piece; (c) a housing seal arrangement positioned on the first end piece at a location with at least a portion of the housing seal arrangement completely surrounding the media.
