<p>Actuator (1) comprising a cylinder (2) in which a piston (8) is longitudinally mobile and which comprises, between this piston and at least one radial end wall (6) of the cylinder, a fluid chamber (9) and means, connected to this chamber, for the fluid to flow out. These outflow means (15) comprise means (19) for limiting the outflow of the fluid when the piston (8) moves, at least in one direction, for part of its stroke. Said outflow means (15) additionally comprise means (30) enabling said limiting means (19) to be avoided when the piston is moving in its other direction. <IMAGE></p> |
