DEVICE FOR MOUNTING EXHAUST GAS REFLUX VALVE

摘要

The present invention relates to a mounting device for an exhaust gas re-circulation valve which prevents the overheating, due to high temperature exhaust gas, of a stepping motor powering the opening and closing of the valve and the valve main body of an exhaust gas re-circulation valve which opens and closes the exhaust gas re-circulation passage of an engine. The valve body 201 of the exhaust gas re-circulation valve is buried in a component 100 of the engine having a lower temperature than the exhaust gas. In such a way, the high temperature of the exhaust gas may be absorbed, dispersed and radiated and as a result there is no need to provide a separate cooling structure such as a coolant chamber and the overheating of the stepping motor 300 due to high temperature exhaust gas may be prevented.
