DISPLACEMENT DRIVE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive is designed for displacing working members of actuating mechanisms. Proposed drive includes bellows designed for connection with pressure building device. Bellows have outline in cross section whose longitudinal dimensions along larger axis exceeds its cross dimensions along smaller axis, larger axes of symmetry of outer inner contours of each corrugation of bellows do not coincide and they are parallel. Bellows are provided with cross bridges connecting outer contours of corrugations of bellows with formation of holes through which all parts of inner space of bellows communicate. EFFECT: provision of quick response of drive in operation. 2 cl, 4 dwg
