INTERNAL TYPE CHECK VALVE OF INTAKE MANIFOLD

摘要

The present invention relates to an internal type check valve of an intake manifold to smoothly operate a diagram by removing foreign substance by a filtering member. The internal type check valve includes a penetration hole which is prepared in the vacuum chamber partition wall of the intake manifold and the plenum chamber partition wall, respectively; an air flowing hole which is prepared on the circumference of the penetration hole of the plenum chamber partition wall and the penetration hole of the vacuum chamber partition wall; a diagram which penetrates the penetration hole of the plenum chamber partition wall and the penetration hole of the vacuum chamber partition wall to be assembled; and a filling member which is combined with the middle part of the diagram. So, the operation trouble due to the foreign substance can be prevented.
