Abstract:
A positive crankcase ventilation valve for venting crankcase gases from a crankcase of an engine of an automotive vehicle, comprising:an elongated valve casing having an inlet at one end adapted to communicate with the crankcase and an outlet at an opposite end adapted to communicate with an engine manifold for the flow of crankcase gases drawn from the crankcase through the valve casing by the engine manifold when the engine is running, a metering pintle in said casing reciprocable inwardly toward the inlet and outwardly toward the outlet, a crossbar in and extending across said casing adjacent to but spaced outwardly of said inlet, and a pressure member resiliently pressing said pintle inwardly against said crossbar when the engine is not running, said pintle being reciprocable outwardly away from said crossbar against the pressure of said pressure member by the flow of the crankcase gases when the engine is running to meter the flow of the crankcase gases.
