Abstract

Изобретението се отнася до задвижващ механизъм за осево изместване на клапан и намира приложение в двигатели с вътрешно горене. 3адвижващият механизъм включва прикрепен към главата (1) на двигателя корпус (2), с оформен кух цилиндър (3), в който има двупосочно подвижно бутало (6) с прът. В корпуса (2), затворен с капачка (4), е предвиден контур за контролирано зареждане и отвеждане на флуида под налягане и управляващ клапан с пряко електромагнитно управление. Управляващият клапан е разположен над буталото (6) и е оформен като плунжер (19), състоящ се от долна цилиндрична удебелена част с аксиални отвори (20) и горна част, в която са оформени централен отвор (22) и радиални отвори (23 и 24). Горната част на плунжера (19) с отворите е разположена в предвидено в капачката (4) пространство (21) и заедно оформят хидравлично спирателно устройство. Буталото (6) представлява кух едностранно отворен цилиндър, в който са поместени един в друг първи (8) и втори (9) спирачни цилиндри с оформени аксиални отвори (12 и 13). Между цилиндрите (8 и 9) е предвидена пружина (10), като цилиндрите са осево подвижни един спрямо друг и спрямо кухия цилиндър (3) и формират основно спирателно устройство. В долния край на кухия цилиндър (3) е предвидено спирачно седло (5). В буталото (6) са предвидени радиални отвори (7), а в корпуса (2) изпускателен канал (14), които оформят допълнително спирателно устройство. 6 претенции, 2 фигури
