Abstract: A valve member having a first flow path and a second flow path, and configured to control both flow paths through a filter assembly. The valve member allows control of the two flow streams in a compact space compared to traditional valves. The valve member may require less space to operate due to its compact nature as compared to traditional external valves with multiple handles that each require space to rotate. The valve member may also be used to easily shut-off flow to a filter of a filter assembly without limiting use of another filtration assembly in the same filtration system. Alternatively, the valve member may shut off flow to a corresponding filter of a stand-alone filter assembly that is not connected to another filter assembly. Also, the valve member allows less expensive and more lightweight filtration systems.

Abstract: A filter assembly has a threaded cover that mates with a complementary thread on the filter housing. Rotation of the housing cover in a first direction moves the cover axially away from the housing, and rotation of the housing cover in a second direction opposite the first direction moves the cover axially toward the housing. An intermittent coupling between a filter housing cover and a filter element applies intermittent axial forces to the filter element as the housing cover is rotated in the first direction to separate the filter element from the housing along with the cover. The intermittent coupling includes components on the inside of the filter cover that engage with complementary components on the filter element during each revolution of the cover.
