Abstract
An oil separator such as used in an air charging system includes a bypass assembly. During normal operation, airflow from an inlet to an outlet passes through the filter to remove oil and oil vapor from the compressed air. If a restriction or blockage occurs in the filter, as exhibited by a predetermined pressure differential across the filter, a bypass passage is opened to allow direct communication between the inlet and outlet ports. A spring defines the pressure responsive member that allows the filter to move away from the valve seat and establish communication between the inlet and outlet ports of the housing.
