  • Patent number: 6814202
    Abstract: A hydrodynamic torque converter is provided with a converter housing to hold at least one pump wheel, one turbine wheel, and one stator to form a hydrodynamic circuit and with at least one axial bearing arrangement for supporting the stator. At least one support element has a bearing side which rests against the axial bearing arrangement, and a stator side which rests against a component of the stator and is designed with at least one flow passage for viscous medium, which forms a connection between at least one flow conduit and the hydrodynamic circuit. The flow passage has a flow bed and, contiguous with that, at least one boundary wall, which leads from the flow bed to the axial level of the corresponding support element side.
