Abstract

Improvements in hydraulic power steering for vehicles comprising, a screw driven by a steering wheel, a female thread engaged with the screw in a rotary mode and inserted in a cavity of a coaxial piston with the same screw, a cylinder inside which is hermetically mounted and said piston slidable, a toothed sector meshed with a serrated portion of the piston to transform the axial locations of the piston in one direction or in the opposite direction in as many angular displacements of the toothed sector, *** see image 01 (Machine-translation by Google Translate, not legally binding)
