Abstract

Inventia se refera la un sistem de directie cu actiune, care cuprinde doi cilindri hidraulici, de actionare cu actiune simpla, interconectati mecanic, fiecare cilindru avînd cîte un piston care separa o camera de presiune care comanda selectiv curgerea fluidului hidraulic de la o pompa de alimentare la camerele de presiune ale celor doi cilindri, niste contacte hidraulice de comanda care leaga o pompa dozatoare actionata manual de supapa de comanda precum si niste racorduri între camerele de reactie ale celor doi cilindri si conductele de comanda respective. în scopul realizarii unui sistem de compensare de reactie de volum constant, printr-o constructie simpla si fiabila, fiecare cilindru de actionare are o a doua camera de reactie pe partea opusa a pistonului, cea de-a doua camera de reactie a primului cilindru de actionare fiind conectata la cea de a doua conducta de comanda, iar a doua camera de reactie a celui de-al doilea cilindru de actionare fiind conectata la prima conducta decomanda.
