Abstract
A piston rod is formed of fiber reinforced material so arranged that an elastic connecting zone is provided between the rod and the piston, thereby avoiding bolting one end of the piston rod to the piston. The cavity inside the piston has a dovetail recess. The fibers are anchored in the cavity and recess by embedding the fibers, which fan out in a uniform distribution from said elastic connecting zone, in a synthetic embedding material.
