ABSTRACT:
A clutch or brake cylinder has an annular working space accommodating an annular piston which confronts a stack of interleaved friction plates adapted to couple the cylinder to a coaxial member rotatable relatively thereto, the piston being displaceable by fluid pressure toward the stack against the force of a Belleville spring. This piston occupies only part of the working space so as to leave an annular clearance in which an ancillary sealing ring is independently slidable. When fluid pressure is applied, part of that pressure pushes the sealing ring against the Belleville spring and lifts it off the piston which then can exert its full force upon the stack of friction plates. Extraction of the cylinder from a surrounding housing enables the piston and the sealing ring to be replaced by a larger piston, filling the entire cross-sectional area of the working space, if a greater coupling pressure is to be exerted.
