Abstract

A throttle device for controlling an internal combustion engine, in which the throttle valve is supported precisely employs a bearing recess serving to support the throttle valve shaft which is surrounded by a clamping element. As a result, there is excellent, durable stabilization of the bearing recess. The throttle device is especially well suited to vehicles that have a throttle-type internal combustion engine.
