Abstract

A multi-disc hydraulically operated friction clutch is provided with valve means in the form of longitudinally split plugs received in the drain openings of the plunger to vary the flow passage area of these openings, depending on the position of the plunger. The plugs are displaced, on the one hand, by contact with the pressure disc of the clutch and, on the other hand, by their abutting against the housing of the clutch. By selecting the ratings of the valve means, i.e. the dimensions of the drain slit in the plugs, it is possible to ensure any required degree of smoothness of engagement of the clutch, the pressure disc acting upon the package of the friction discs with a gradually varying effort, proportional to the rate of draining of the working fluid through the plunger.
