Abstract

An apparatus for actuating the throttle valve of an internal combustion engine, in particular a drive slip control (ASR) and engine drag moment control (MSR), with a disconnect point disposed in the course of the gas pedal transmission linkage overcome by spring forces acting on both sides of it. In the normal situation the throttle valve position corresponds to the driving pedal position, while in attaining ASR functions the disconnect point is opened, by the action of an electromagnetic or electric-motor element, and the position of the throttle valve is adjusted independently, regardless of the intention of the operator, in order to reduce the drive slip.
