Abstract
An integrated assembly includes a primary housing which carries the filter element. A partition resides in a secondary housing which seals off an atmospheric chamber from a pressure regulator chamber. The partition is moveable in a first axial direction and a second axial direction opposite the first axial direction response to a change in a pressure drop across the filter element. A valve assembly changes from a closed configuration to partially open configurations, and to a fully open configuration responsive to movement of the partition. The movement of the valve keeps a pressure in a crankcase downstream of said filter.
