Abstract
A torque converter having a fluid vibration damping arrangement (70) for damping torsional vibrations which lead to relative torsion between an input and an output side of the torsional vibration damper by means of fluid contained in the interior (24) of the casing (12). The fluid vibration damping arrangement is implemented by at least one first blade-like projection, which is coupled in a rotationally fixed manner to a turbine impeller shell (28) of the turbine impeller (26), and extends substantially axially away from said shell and toward the clutch element (44), and at least one second blade-like projection, which is coupled in a rotationally fixed manner to the clutch element (44), preferably attached to the latter, and extends substantially axially away from the latter and toward the turbine impeller (26). The at least one first blade-like projection (74) and the at least one second blade-like projection (72) overlapping in the axial direction in certain regions.
