A piston arrangement includes, but is not limited to a hydraulically-actuated piston to move a piston rod within a cylinder to pivot a clutch actuating lever, the end of the cylinder being sealed by a boot-type seal having a central hole, though which the rod slides in a reciprocating manner. The seal is flexible to permit transverse movements of the piston rod and has a peripheral flange by means of which it is attached to the cylinder end. |
