Ventilelementmechanismus für ein Abgaszirkulationsventil

A valve element mechanism for an exhaust gas circulation valve has: a primary eccentricity A causing a center O of a support shaft 4 rotatably provided in a housing 2 to separate from a centerline P of a seal surface 2b of a valve seat 2a with which a valve element 5 opening and closing a fluid pass...

Beschreibung
Zusammenfassung:	A valve element mechanism for an exhaust gas circulation valve has: a primary eccentricity A causing a center O of a support shaft 4 rotatably provided in a housing 2 to separate from a centerline P of a seal surface 2b of a valve seat 2a with which a valve element 5 opening and closing a fluid passage by being rotated by the support shaft 4 contacts; a secondary eccentricity B causing the center O of the support shaft 4 to separate from a centerline Q of the housing 2, and a tertiary eccentricity C causing an apex G of a cone shape 6 defining a seal surface 5a of the valve element 5 and the seal surface 2b of the valve sheet 2a to position at a side opposite from the support shaft 4 and to tilt against a centerline of the housing 2.
