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.
Claims10
A piston head and piston rod structure for prime movers having a rotating crankshaft, comprising a loop formed of fiber strands embedded in synthetic resin, said fiber strands forming a bight for holding crankshaft bearing means in said bight at the free end of said piston rod, said fiber strands converging from both sides of said bight toward said piston head for forming a flexible piston rod hinging zone, said strands having ends flaring out of said flexible piston rod hinging zone, and anchoring means operatively securing said flaring strand ends in said piston head, whereby said flexible piston rod hinging zone provides a hinging joint for lateral excursions of the piston rod resulting from crankshaft rotations, said strands, anchoring means and piston head forming an integral structure, without a piston bolt.
