  • EGR system having fast-acting EGR valve
    Patent number: 5435519
    Abstract: The magnetic circuit has an air gap on the interior of the bobbin-mounted coil. A non-ferromagnetic cylindrical sleeve lines the interior of the coil. The armature is disposed within the sleeve and has a cylindrical wall with an axial taper proximate the air gap. The sleeve extends to seal against a bushing that guides a portion of the valve member between the solenoid and the valve head so that any exhaust gases that infiltrate through the bushing to the solenoid are confined within the sleeve.
