Abstract: A hydrodynamic torque converter with a pump, a turbine and a stator, having an increased thickness on the suction side of blade profiles of blades in the stator relative to the pressure side of the blades, in order to reduce the pump torque of the torque converter at low to medium speed ratios without influencing the other features of the characteristic diagram.

Abstract: The invention relates to a hydrodynamic torque converter comprising an impeller (12) arranged. inside a housing and a turbine (14) and at least one stator blade (18) of a stator (16) arranged between the impeller and the turbine, the rear blade surface of the stator blade having a flat section (30).

Abstract: The invention relates to a hydrodynamic torque converter having a pump shell including blades, a turbine shell including blades, a torus-shaped flow cycle. The blades are configured to be attached at the respective shells through inner walls and the inner walls of the turbine shell and of the pump shell form an inner torus with outer surfaces facing the flow cycle and an end of an extension of the inner wall of at least one shell and an end of an extension of an adjacent shell are disposed in a plane and extend over one another and define a gap between one another. A transition from the extensions is configured to be hydrodynamically smooth.

Abstract: A stator shell for a hydrodynamic torque converter (1), wherein said stator shell (2) comprises a plurality of blades (32, 34), wherein said stator shell (2) comprises plural components (20, 22), produced separately from one another and respectively comprising one or plural blades (32, 34) of said stator shell (2), wherein said components (20, 22) are fixated to one another and disposed relative to one another, so that blades (32, 34) of several of said components (20, 22) are disposed respectively offset relative to one another in a circumferential direction forming gaps provided in said circumferential direction extending about a central axis of the stator shell (2), wherein each of said blades (32, 34) is configured from an integral component between its respective leading edge and its respective trailing edge, so that each of the blades (32, 34) is respectively configured integrally from one of the components (20 or 22).
