Abstract
For the displacement of a throttle valve (1) which is rotatably mounted in the intake connection (2) of an internal combustion engine, there is provided a device with electromotive actuating drive, gearing and clutch (10) as well as electronic control device (11) with which the entire load range, in addition to the idle range, can be automatically controlled. In this connection, a coupling member (15) is provided between the pulley (8), which is mechanically coupled to the gas pedal (6), and a first lever (13) which is rigidly attached to the throttle-valve shaft (1a). Furthermore, the main return spring (3) acts directly on the pulley (8), the coupling member (15) is urged by a coupling spring (16) against the first lever (13) of the throttle-valve shaft (1a), and a third return spring (19) acts on the driven shaft (18) of the actuating drive (9)
