Abstract
A pressure cylinder has a piston actuated by a force-input rod. An enlarged head of the rod is engaged by a washer and the assembly retained within the cylinder by a cup-shaped retainer press-fitted into the cylinder open end. An outer surface of the retainer is flush with the adjacent axially outermost surface of the cylinder and engages a support, to which the cylinder is fixed, in order to transmit to the support retraction forces sustained by the rod.
