ABSTRACT:
A two stage valve for regulating the ventilation of gases from the crankcase of an internal combustion engine, where the flow of gases from the crankcase through the valve and into the intake manifold is limited whenever engine loads are relatively low regardless of engine vacuum and where the flow of gases from the crankcase through the valve and into the intake manifold is relatively large whenever engine loads are relatively large.
