Friction coupling, in particular for application between a combustion engine and a reversing gear, said coupling comprising at least one axially shiftably friction ring 19, 20 and an annular disc 18 and sealing ring 27, 28 cooperating with this for engaging and disengaging the ingoing and outgoing shifts 5, 11 of the coupling, sealed areas 21, 31, 22, 32 being formed between the friction ring, sealing ring and annular disc to which area a pressure medium can be supplied for engaging and disengaging the coupling, the coupling being maintained in engaged position by roller elements being positioned between inclined slanting faces in opposed end faces of the friction ring and the annular disc. A control valve 55 and further valve means in the disc 18 control the pressure medium and prevent excessively fast changes between forward and reverse. <IMAGE> |
