Abstract
PURPOSE: To provide a seal to a valve spindle to drive an exhaust-gas return control valve, and arrange a spring under the seal to scrape off carbon and other extraneous matters stuck between the seal and the valve spindle.
CONSTITUTION: A control valve 6 is arranged in an exhaust gas return passage 13. The control valve 6 is fixed to a diaphragm 2 of a diaphragm device 1 via a valve spindle 7. A saucer member 14 through which the valve spindle 7 is fitted is provided between a casing 11 and a body 10. The saucer member 14 is also provided with a seal inside to prevent the leakage of exhaust gas in the passage 13. A spring 8 with an inside diameter a little larger than the outside diameter of the valve spindle 7 is provided between the body 10 and the seal 12, and the carbon stuck on the valve spindle 7 is scraped off by this spring 8.
