It is described an actuation device using, for the active element, a flexible bellows operated by a pressurized fluid (usually, but not necessarily, at a pressure higher than the ambient one). The bellows is housed, for the most part of its length, inside a cylindrical cavity having the inner diameter slightly larger than the bellows outer one, so that the bellows is free to vary its length, but is restrained to bend sideways and therefore can be operated by high pressure.
La présente invention concerne un dispositif actionneur utilisant, comme élément actif, un soufflet souple mis en oeuvre à l'aide de fluide pressurisé (habituellement, mais pas obligatoirement, à une pression plus élevée que la pression atmosphérique). Le soufflet est logé, pour la plus grande partie de sa longueur, dans un compartiment cylindrique dont le diamètre intérieur est légèrement plus grand que le diamètre extérieur du soufflet, de manière à ce que le soufflet puisse librement varier dans sa longueur, mais soit empêché de se courber latéralement, et puisse ainsi fonctionner à des pressions élevées.
