Abstract

Procedeu pentru comanda hidraulica a supapelor motoarelor cu ardere interna, cu piston cu miscare de translatie, supape de admisie si de evacuare, la care sunt deplasate cantitati mai mari de lichid de comanda, de catre un cilindru hidraulic de actionare, decît sunt necesare pentru comanda, de catre un cilindru hidraulic de actionare, decît sunt necesare pentru comanda de deschidere si de închidere a supapei de admisie sau a supapei de evacuare respective, astfel încît la supapa deschisa lichidul de comanda în exces este îndepartat dintr-un cilindru de lucru care actioneaza supapa si la care o modificare a momentului deschiderii si a momentului închiderii supapei de admisie sau supapei de evacuare se realizeaza prin deplasarea unui mijlocd e reglare de la cilindrul hidraulic de actionare, si la fiecare actionare a supapei de admisie sau de evacuare, în timpul cursei de detenta a cilindrului hidraulic de actionare, în întregul sistem hidraulic de comanda este umplut din nou prin aspiratie suplimentara de lichid de comanda dintr-un rezervor pentru lichid de comanda, prin intermediul unor mijloace de blocare....
