Abstract
A hydrodynamic coupling, whose degree of filling is determined by a scoop tube, has a plurality of radially arranged elongated depressions on the inner surface of the coupling casing (simultaneously forming a scoop chamber) driven on the primary side. These depressions have the purpose of efficiently causing rotation of the oil ring formed inside the scoop tube chamber so that the oil ring rotates as far as possible at the same speed as the coupling casing. Owing to the small size of the radial depressions in a fine arrangement on the inner surface of the coupling casing the occurrence of pressure fluctuations at the scoop tube and the hydraulic system downstream therefrom is avoided.
