FIELD: mechanical engineering. SUBSTANCE: proposed drive is designed for displacement of actuating mechanisms. Drive includes bellows designed for connection with pressure building device. Bellows have outline in cross section whose longitudinal dimension along larger axis exceeds its cross dimension along smaller axis. Bellows are provided with cross bridges connecting outer contours of bellows corrugations with formation of holes through which all parts of inner space of bellows communicate. EFFECT: provision of quick response of drive. 2 cl, 3 dwg
