Abstract

The hydromechanical device () for supplying each of two opposing active chambers (vrca, vrca) of a double-acting receiving cylinder (vr) for servo-controlled operation of at least one first output rod (vrts, vrts) INCLUDES: a first double-acting generating cylinder (vg) INCLUDING a first movement input rod (vgte) which is rigidly connected to a first piston (vgp) that delimits two first opposing passive chambers (vgcp, vgcp), each of which is selectively connected to at least one of THE two opposing active chambers of the receiving cylinder (vr); and an assembly () for driving the first rod (vgte) of the first generating cylinder (vg), INCLUDING a movement-transforming screw-nut assembly (), one movement output component () of which is rigidly connected to the first rod (vgte) of the first generating cylinder (vg) and the other movement input component () of which is rotated by a drive motor (m).
