| 摘要 |
The invention relates to a hydrodynamic coupling comprising an impeller (1), which propels a drive machine and a turbine wheel (2), which propels a drive machine. The turbine wheel and its rotationally fixed coupling shell (4) form a coupling housing (5). A centrifugal force valve (6) comprising a valve body (6.1) that is actuated using centrifugal force, is located in the outer peripheral region of the coupling housing, said valve being mounted in an outlet (7) for working medium from the working chamber, in such a way that the valve body essentially or completely seals the outlet when the centrifugal force valve is closed and releases said outlet when the valve is open, allowing the working medium to flow out. The valve body of the centrifugal force valve is supplied with working medium exclusively on its radial inner face and its radial outer face is subjected exclusively to the action of an elastic, mechanical pressure element (6.2), which acts in the closing direction of the centrifugal force valve.
