Throttle flap element actuating device for combustion engine intake manifold system, uses electrically driven rotary magnet as drive element with rotor joined torsionally tight to throttle flap element shaft

摘要

Throttle flap actuating elements in the intake manifold system, including electric rotary actuators for the throttle flap which normally require a comparatively large installation space in the region of the intake system, and by designing the drive device as an electrically driven rotary magnet (9) the rotor (8) of the rotary magnet (9) can now be joined torsionally-rigidly with the shaft of the throttle flap element to reduce space.
