Abstract

Improvements in distributors for hydraulic power steering of the type that include a screw driven by the steering wheel, a female thread rotatably coupled on the screw and inserted in a cavity of a piston coaxial with the said screw, a cylinder inside which is mounted so slidable and hormotically the aforementioned piston, a toothed sector meshed with a section of the piston to transform the axial displacements of the piston in one direction or in another opposite in as many angular displacements of the dentate sector, *** see image 01 (Machine-translation by Google Translate, not legally binding)
