Abstract

A setting lever (8) adapted to be turned mechanically is seated in turnable manner on a throttle-valve shaft (2) of a throttle-valve connection (1). A driver arm (12) of the setting lever engages between two legs (10, 11) of a coupling spring (9). Another driver arm (13) which is firmly attached to the throttle-valve shaft (2) also engages between said legs (10, 11). In this way an electric motor (4) which is developed as stepping motor can turn the throttle-valve shaft (2), for instance, on a basis of commands of an anti-slip control or of a speed control, regardless of the position of the setting lever (8).
