Abstract
A device (1) for actuating at least one piston (2) moving axially in the bore (3) of a body (4), the piston (2) being driven by the longitudinal or curved movement (F2) of a control arm (5). Also disclosed is a method for detecting a failure in a device (1) having an intermediary element (6), located between the piston (2) and the control arm (5), this intermediary element (6) being also used as an alarm means should the intermediary element (6) be missing between the piston (2) and the arm (5). The invention is particularly applicable in the field of diagnosis.
