Abstract

Ein Drosselklappenstutzen 10 mit einem Gehäuse 12, in dem eine durchgehende Drosselöffnung 34 ausgebildet ist, die durch eine auf einer Drosselklappenwelle 16 angeordnete Drosselklappe 36 verschließbar ist, wobei die Drosselklappenwelle 16 mit ihren seitlichen Enden 18, 20 in Lagerausnehmungen 22, 24 des Gehäuses 12 ragt und drehbar gelagert ist, wobei ein Ende 20 der Drosselklappenwelle 16 auf der der Drosselklappe 36 abgewandten Seite 40 der Lagerausnehmung 24 heraus- und eine Bohrung 42 eines Halteelements 44 durchragt, das axial unverschiebbar auf der Drosselklappenwelle 16 angeordnet und axial in dem der Drosselklappe 36 abgewandten Mündungsbereich 74 der Lagerausnehmung 24 an dem Gehäuse abgestützt ist soll eine besonders hohe mechanische Stabilität einer Axialsicherung 14 aufweisen. Hierzu ist das Halteelement an seinem radial äusseren Bereich 92, 94 mit dem Gehäuse 12 fest verbunden und im Bereich seiner Bohrung 42 axial auf jeder Seite 52, 54 an einem annähernd ringscheibenförmigen Sicherungselement 46, 48 in Anlage, wobei die Sicherungselemente 46, 48 fest auf der Drosselklappenwelle 16 angeordnet sind und die Drosselklappenwelle 16 frei drehbar die Bohrung 42 des Halteelements 44 durchragt.

Figure 00000001
A throttle valve assembly 10 with a housing 12, in which a continuous throttle opening 34 is formed, which can be closed by a throttle valve 36 arranged on a throttle valve shaft 16, the throttle valve shaft 16 projecting with its lateral ends 18, 20 into bearing recesses 22, 24 of the housing 12 and is rotatably mounted, with one end 20 of the throttle valve shaft 16 protruding on the side 40 of the bearing recess 24 facing away from the throttle valve 36 and projecting through a bore 42 in a holding element 44 which is arranged axially immovably on the throttle valve shaft 16 and axially in that facing away from the throttle valve 36 The mouth area 74 of the bearing recess 24 is supported on the housing and should have a particularly high mechanical stability of an axial securing device 14. For this purpose, the holding element is fixedly connected to the housing 12 at its radially outer region 92, 94 and axially in the region of its bore 42 on each side 52, 54 against an approximately annular disk-shaped securing element 46, 48, the securing elements 46, 48 being firmly attached the throttle valve shaft 16 are arranged and the throttle valve shaft 16 rotates freely through the bore 42 of the holding element 44.
