Abstract:
A bypass assembly for an oil separator in an air charging system comprising:a cylindrical housing having an inlet for receiving supply air and an outlet for delivering air, both said inlet and said outlet being located proximate to one end of the cylindrical housing;an annular oil removal member interposed between the housing inlet and outlet for removing oil, particulate and liquid water from air; said annular oil removal member dimensioned for receipt in the housing so as to provide an annular space between the oil removal member and the housing, and for receiving airflow axially therethrough;a biasing member urging the oil removal member against the housing at the end that is proximate to said inlet and outlet below a predetermined pressure differential between said inlet and said outlet; anda passage between said inlet and said outlet that does not pass through said annular space for selectively bypassing the oil removal member and communicating between the housing inlet and outlet in response to movement of said oil removal member away from the housing at the end that is proximate to said inlet and outlet in response to a pressure differential between the inlet and outlet that exceeds said predetermined pressure differential.
