Abstract

Impeller and turbine wheels form a toroidal working chamber of a hydrodynamic clutch filled with working medium. A throttle plate extends circumferentially near a central diameter of the working chamber The throttle plate moves axially, from an inactive position with little or no throttling effect on a circular flow of the working medium, to an active position with a greater throttling effect on the circular flow. The working chamber is without a center wall, such that the throttle plate is directly enclosed by the flow zone of the working chamber in both the active and inactive position of the throttle plate. The inactive position is located in the area of a separation gap between the impeller and the turbine wheel.
