Abstract
One of the driving and driven parts of the coupling is connected to a cylinder and the other to a piston which delimit therebetween two antagonistic chambers. The chambers have a substantially constant volume, are filled with a practically incompressible hydraulic liquid, and are interconnected through two unidirectional circuits which have opposite directions and each a substantially constant volume. A distributing device 22 is so arranged as to either bring into action one or the other of the unidirectional circuits, or to neutralize both of them.
