ABSTRACT:
A blade of an impeller for a hydrodynamic torque converter wherein the central flow thread at the point of the leading edge is displaced with respect to a central flow thread at a point of the trailing edge along a smaller wheel diameter as well as by an angle of rotation leading in a direction of rotation of the impeller. The trailing edge is disposed in a radial plane at least approximately perpendicular to an axis of rotation of the impeller. The leading edge of the point of the central flow thread has a leading angle of about 30.degree. to 40.degree. and the trailing edge is inclined in such a way that its corner point at an inner torus, delimiting an inner side of the impeller, is displaced by an angle of rotation in the direction of rotation toward the front with respect to its corner point at the outer torus which delimits the outer portion of the impeller.
