Abstract:
1. A throttle valve body for an internal combustion engine, comprising a housing and a crossflow opening in the housing, which can be blocked by a throttle valve, the throttle valve being arranged on a throttle valve shaft which can be driven so as to pivot about its longitudinal axis extending transversely with respect to the longitudinal axis of the crossflow opening and whose free ends are mounted such that they can pivot in bearings which are arranged in bearing recesses in the housing, and the throttle valve shaft being secured against axial displacement by an axial safety device, in its regions in which the throttle valve shaft protrudes axially, the throttle valve having run-on surfaces which bear on supporting regions fixed to the housing, characterized in that the supporting regions are those ends of the bearings which are oriented toward the crossflow opening, and the throttle valve has a holding sleeve, in whose axial recess the throttle valve shaft is firmly arranged and whose ends form the run-on surfaces.
