Abstract

Машината е с приложение в хидротехническото строителство и при добив на полезни изкопаеми в рудниците. Тя е с опростена конструкция и управление, с повишена надеждност при работа и намалена енергоемкост. Съдържа пробивен инструмент (1), свързан с хидродвигател (3), хидроударник (4), съединен чрез хидроразпределител (15) с напорна (11) и със сливна (21) хидромагистрала, и устройство (16) за принудително изсмукване на течността от работната камера на хидроударника (4) при неговия обратен ход. Устройството (16) съдържа камера (17) за смесване, включена към сливната линия на хидроударника /4/, ежектор (18), включен към сливната линия на хидродвигател (3), и дифузор (19), който е включен към обща сливна хидромагистрала (21) и в който е разположена дюзата на ежектора (18).1 претенция, 1 фигура
