Abstract
Inventia se refera la un sistem hidrostatic de directie care cuprinde doua elemente de actionare hidraulice, constituite fiecare din cîte un cilindru cu simpla actiune în care se deplaseaza cîte un piston astfel încît sa se formeze cîte o camera de presiune si cate o camera de reactie, o supapa directionala care comanda selectiv curgerea fluidului hidraulic de la o pompa de alimentare sa camerele de presiune si niste conducte care conexeaza elementele constituite ale sistemului. Sistemul hidrostatic de directie, conform inventiei, în scopul corectarii diferentei între vitezele pistoanelor din elementele de actionare hidraulica, în timpul virajului printr-o constrctie simpla si fiabila sare montate între cele doua conducte la camerele de reactie ale cilindrilor subsistemelor de antrenare hidraulica, o supapa de compensare care este sensibila la diferenta de presiune dintre cele doua conducte limitînd aceasta diferenta la o valoare predeterminata.
