  • Patent number: 7131433
    Abstract: A positive crankcase ventilation valve assembly is provided. The positive crankcase ventilation valve assembly includes a housing having a first end and a second end and a flow path therebetween. A positive crankcase ventilation valve is provided and positioned relative to the housing first end and in fluid communication with the housing flow path. A baffle is provided and positioned in the housing and in fluid communication with the housing flow path, wherein the baffle is arranged to allow crankcase gases to flow through the baffle and into the positive crankcase ventilation valve while preventing engine oil from traveling beyond the baffle.

  • Patent number: 6820601
    Abstract: A positive crankcase ventilation valve for venting crankcase gases from a crankcase of an engine has a valve casing with an inlet adapted to communicate with the crankcase and an outlet adapted to communicate with an engine intake 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 reciprocates in the casing. A crossbar extends across the casing adjacent to the inlet. A spring presses the pintle against the crossbar when the engine is not running. The pintle is moved away from the crossbar against the pressure of the spring by the flow of the crankcase gases when the engine is running to meter the flow of the crankcase gases. The crossbar is a narrow roll pin so that if moisture between the roll pin and pintle freezes when the engine is not running, the frozen moisture will quickly break away when the engine is started.
