Abstract

Клапан для приведения в действие гидравлического цилиндра, в частности углового цилиндра, секции механизированного крепления при подземных строительных роботах. В состав клапана входит по крайней мере один клапанный поршень, который перекрывает проточный канал внутри клапана, причем проточный канал (48, 50) не проходит сквозь клапанный поршень (40), а клапан имеет элемент (Р1) для подсоединения рециркуляционной линии (R), которая продолжительное время соединена с клапанным поршнем (40). Для уменьшения сил, которые действуют на седло клапана, клапанный поршень (40) с обеих сторон соединен с соединительным элементом рециркуляционной линии. Изобретением предусмотрен способ установки секции механизированного крепления с помощью клапана.
