Steering valve with spring torsion rod

摘要

A torsion rod is provided with articulated connections at opposite ends to transmit torque between a steering spindle and the universal shaft coupling of a pump rotor in a steering control valve. The end of the torsion rod coupled to the universal shaft is received in a bore that terminates close to the driven end of the universal shaft engaged with the pump rotor, the articulated connection to the torsion rod being located at said terminal end of the bore.
