Abstract
A decelerating device includes a casing defining internally a chamber filled with a viscous fluid, e.g. silicone oil; and a movable member fitted in fluidtight manner to the casing, so as to be housed at least partly inside the chamber and immersed in the viscous fluid. The movable member has a partition for dividing the chamber substantially in fluidtight manner into at least two adjacent portions varying in volume as a function of the position of the movable member with respect to the casing; and a calibrated constriction for maintaining permanent hydraulic connection of the at least two adjacent portions of the chamber, so that the viscous fluid flows between the chamber portions as a consequence of relative motion between the movable member and the casing.
