ABSTRACT:
This hydromechanical automatic reversing device for linear hydraulic rams operates by inertia and comprises a support block mounted to the ram body, a pendular arm pivoted at one end to the spool of the reversing valve associated with the ram, and, at the opposite end, to an eccentric pin trunnioned in the support block. A shaft rigid with and parallel to the ram piston rod is provided with a pair of adjustable stops adapted to engage by turns the eccentric pin of the pendular arm for shifting the spool of the reversing valve, for reversing the direction of movement of the ram.
