Abstract
The hydrodynamic control coupling has primary and secondary vane wheels (2,4 respectively) inclined to the coupling axis (20) and a working space (5) which is provided with an inlet (6) and an outlet (7) for the working medium, the working medium capable of being diverted from the working space into a receiving chamber (10) via tangential bores (7) running in the direction of the flow, a valve (8) being provided which determines the rate at which the working space fills. In accordance with the invention, the receiving chamber for the working medium is located radially inwardly of the working space and is defined by walls of the primary and secondary vane wheels. Such an arrangement of the coupling enables it to be constructed with smaller dimensions and to be simply controlled.
