Abstract

Die Erfindung betrifft ein Abgas-Steuerventil mit einem ersten Ventilteil (14) und einem zweiten Ventilteil (44), die mit einer Seite (17, 46) aufeinanderliegen, jeweils Durchlässe (15,45) aufweisen und relativ zueinander zwischen einer den Durchgang von Abgas freigebenden Öffnungsstellung und sperrenden Schließstellung verdrehbar sind. Entlang den die Durchlässe (15,45) im ersten Ventilteil (14) umgrenzenden Begrenzungskanten (18 bis 20) verlaufen zu einer Axialseite des ersten Ventilteils (14) überstehende, die Durchlässe (15) umrahmende Stege (21 bis 23), die mit ihren freien Schmalflächen Auflageflächen für das zweite Ventilteil (44) bilden, das auf seiner dem ersten Ventilteil (14) zugewandten Seite (46) ebenflächig ausgebildet ist und mit dieser ebenen Fläche auf den Schmalflächen der Stege (21 bis 23) aufliegt und bei der relativen Drehverstellung gleitet (Fig. 1).

Figure imgaf001
The invention relates to an exhaust gas control valve having a first valve part (14) and a second valve part (44) with one side (17, 46) on each other, each having passages (15,45) and relative to each other between the passage of exhaust gas releasable opening position and locking closed position are rotatable. Along the boundary edges (18 to 20) surrounding the passages (15, 45) in the first valve part (14) extend to an axial side of the first valve part (14) protruding, the passages (15) framing webs (21 to 23), with their free narrow surfaces support surfaces for the second valve member (44), which on its the first valve part (14) facing side (46) is planar and rests with this flat surface on the narrow surfaces of the webs (21 to 23) and in the relative rotational adjustment slides (Fig. 1).
