Abstract
An apparatus is proposed which serves to control the position of a throttle device disposed in the intake tube of an internal combustion engine. The apparatus includes a lever, which is joined to a shaft of the throttle device and has both a stop screw arranged to cooperate with a stop and an adjusting screw arranged to cooperate with a feeler pin. The feeler pin traces the position of a control body provided with a cam track and the control body can be displaced to a variable extent in a guide bore by means of an expansion element and thereby bring about a variably large rotation of the throttle device and hence a variably large opening of the cross section for the aspirated air during engine idling in the warm-up phase.
