Patent attributes
A filter assembly includes a housing and an inner post with a fluid inlet passage extending in the housing. An outer post surrounds the inner post to define a fluid outlet passage. A filter cartridge is received around the inner post and the outer post. The filter cartridge includes a filter element. A first endplate, which defines a first opening, is attached to a first end of the filter element. A first seal is received in the first opening to seal between the inner post and the first endplate. A second endplate, which defines a second opening, is attached to a second end of the filter element. A seal is received in the second opening to seal the outer post with the second endplate. The housing and the filter cartridge define an outer cavity. The fluid inlet passage opens into the outer cavity to minimize back flushing of contaminants.
