The pressure-operated clutch has seals (38a,38b,40a,40b) to seal the pressure zones (24a,24b), which are fitted so that they are not in constant contact with the walls (4,18,20,22) of the pressure zones (24a,24b) to be sealed. A moving seal (40a,40b) is set on a neighboring wall (18,20) during a clutch operation and/or a moving wall (18,20) is placed on a seal (38a,38b). The seals (38a,38b,40a,40b), of an elastic material, are self-supporting in grooves. |
