DEVICE FOR ACTUATING A CONTROL MEMBER

摘要

The invention relates to a device for actuating a control member, particularly a throttle valve (4) in a gas conduit (3), such as for example an intake of an internal-combustion engine, which valve is pivotable into operating positions by means of a valve shaft (5), an actuator (11a) being provided, which actuator consists of a rotor body, serving as an actuator body (9) and arranged on the valve shaft (5), and of an electrically energisable excitation section (11), which cooperates with said rotor body, and a position sensor (20) detecting angular positions of the valve shaft (5), which sensor comprises an angular-position generator (9, 22) and an angular-position detector (23), which are associated with one another and of which one of the two is mounted so as to be rotatable, the valve shaft (5) itself being constructed to carry the angular-position generator (9, 22) or angular-position detector (23), and the associated part of the position sensor (20) being stationarily mounted on the housing (2) of the device.
