Abstract
Dispozitivul hidraulic de deblocare pentru ventile de dirijare, conform inventiei, poate fi utilizat la pluguri rotative, pentru ca ventilele de dirijare sa se afle totdeauna în pozitia de comutare dorita si sa ramîna asigurate în aceasta pozitie, pentru care perimetrul piesei de blocare prezinta în zona scobiturilor de blocare doua raze care difera între ele ca marime, iar cursa maxima a boltului de blocare se stabileste în asa fel ca, în mod normal, piesa de blocare sa nu poata fi rotita cu un dinte care este format de catre razele diferit de mari si care, transportat la punctul de rotire a piesei de blocare este mai înalt, putînd fi utilizate ca dispozitive pentru pluguri rotative, în care caz razele diferit de mari se afla între pozitia de comutare pentru mersul liber si pozitia de lucru, de asemenea, la boltul de blocare este executata o canelura de scurgere, care poate fi pusa în legatura cu camera de presiune, a carei sectiune de scurgere este mai mare decît sectiunea de aductie a ajutajului de strangulare, în continuare,...
