Swirl producing device for use in exhaust gas turbocharger in internal-combustion engine of motor vehicle, has guide vane movably arranged with respect to vane length that extends in radial and/or transverse directions in flow channel

摘要

The device (4) has a guide vane (10) arranged in a flow channel (5) in an activated condition. The guide vane is movably arranged with respect to a vane length (13) that extends in radial and/or transverse directions in the flow channel relative to a longitudinal middle axis (8) of the flow channel. The guide vane accomplishes a rotating movement around a longitudinal middle axis (18) of the guide vane, where the longitudinal middle axis of the guide vane runs transverse to the longitudinal middle axis of the flow channel.
