Abstract: A hydrodynamic torque converter is constructed with a converter circuit which comprises at least an impeller wheel, a turbine wheel and a stator wheel. An inner wall connecting the individual blades is provided at both the impeller wheel and at the turbine wheel. The inner walls form an inner torus. The radially inner ends or the radially outer ends of the inner walls have extensions axially toward the other wheel. The extension of the front one of these walls, considered in the direction of flow, has a lengthening extending toward the other wheel, by which lengthening the extension overlaps the extension at the other wheel by a predetermined axial length with a predetermined radial offset in the direction of flow.

Abstract: A torque converter comprises a converter housing that has a plurality of connection areas on one axial side. The converter housing is connectable in rotation-proof fashion relative to a crank shaft at connection points located in the connection areas. The converter housing has a plurality of radially extending hollows arranged in the circumferential direction at a distance from each other on the aforementioned axial side. A first distance between one of the hollows and the hollow directly adjacent to it in one circumferential direction is different from a second distance between the one of the hollows and the hollow directly adjacent to it in the other opposing circumferential direction.
