Abstract
A multi-cylinder assembly includes a cylinder assembly defining a bore and a piston-rod assembly slidably disposed in the bore of the cylinder assembly. The piston-rod assembly includes a piston rod, a piston-rod sleeve and a retainer. The piston rod includes a piston head, a first rod extending outwardly from the piston head and a rod extension extending outwardly from the first rod. The piston-rod sleeve is disposed about the rod extension of the piston rod. The piston-rod sleeve includes a head portion and a rod portion. The retainer is engaged to the rod extension. The retainer prohibits axial movement of the piston-rod sleeve.
