  • Closed crankcase breather system
    Patent number: 6418917
    Abstract: A separator (20) for a closed crank case ventilation system has an upstream located inlet (18) and downstream gas and oil outlets (30, 22). A plurality of flat plate baffles (58) alternately extend from opposing side walls to form a tortuous path for blow by gasses to separate the oil from the gasses. The separator (20) is located upstream from the crankcase depression regulator (34) such that the pressure differential between the separator and the crankcase (28) is minimal to allow the oil to easily open the check valve (26) and return to the crankcase.
