  • PZEV exhaust gas recirculation valve with activated carbon
    Patent number: 7478631
    Abstract: An exhaust gas recirculation valve includes a body including a passageway extending between an inlet and an outlet. The passageway communicates a flow of the exhaust gases. A bearing, disposed in the body, has a bearing passageway. A valve member is located in the passageway between the inlet and outlet and has a portion movably disposed in the bearing passageway such that a clearance path is defined between the portion of the valve member and the bearing. The clearance path is in communication with atmosphere through openings in the body. The valve member is constructed and arranged to regulate the flow of the exhaust gases. Activated carbon is associated with a portion of the body so as to adsorb hydrocarbons associated with the clearance path and thus prevent hydrocarbons from escaping to the atmosphere through the openings in the body.
