Abstract

The invention relates to a device for actuating a control member, particularly a throttle valve in a gas conduit, such as for example an intake of an internal-combustion engine, which valve is pivotable into operating positions by means of a valve shaft, an actuator being provided, which actuator consists of a rotor body, serving as an actuator body and arranged on the valve shaft, and of an electrically energizable excitation section, which cooperates with said rotor body, and a position sensor detecting angular positions of the valve shaft, which sensor comprises an angular-position generator and an angular-position detector, which are associated with one another and of the two is mounted so as to be rotatable, the valve shaft itself being constructed to carry the angular-position generator or angular-position detector, and the associated part of the position sensor being stationarily mounted on the housing of the device.
