Abstract

A hydrodynamic torque converter (1) with a pump wheel (3) and with a turbine wheel (4), and with a torsion damper (8) and with an intermediate space (12) located between the turbine wheel (4) and the torsion damper (8), and with a torus formed by the pump wheel (3) and the turbine wheel (4) for hydraulic fluid. A flow-guiding wall (14) is provided, which deflects a radially outward flow of hydraulic fluid coming from the torus, back radially inward to the intermediate space (12).
