Abstract (en)
[origin: US4836163A] In the throttle butterfly (2) of a throttle-butterfly connector piece of an internal combustion engine there is provided an expansion member (5) which has two arcuate pieces (6,7) which extend out of the circumferential surface of the throttle butterfly (2). The free ends of the arcuate pieces (6, 7) rest against a setting surface (8) which is provided on the housing (1) of the throttle-butterfly connector piece. The setting surface (8) is developed in such a manner that the arcuate piece (6, 7) is spread andt he surface of the throttle buterfly (2) is increased with small angles of opening as compared with what it is in its closed condition.

In der Drosselklappe (2) eines Drosselklappenstutzens einer Brennkraftmaschine ist ein Spreizkörper (5) vorgesehen, der mit zwei Bogenstücken (6, 7) aus der Umfangsfläche der Drosselklappe (2) ragt. Die freien Enden der Bogenstücke (6, 7) liegen gegen eine Stellfläche (8) an, die am Gehäuse (1) des Drosselklappenstutzens vorgesehen ist. Die Stellfläche (8) ist so gestaltet, daß die Bogenstücke (6, 7) gespreizt und die Drosselklappe (2) bei kleinen Öffnungswinkeln großflächiger wird als im geschlossenen Zustand.
