Abstract

L'invention concerne un dispositif d'actionnement pour déplacer un capot mobile d'un inverseur de poussée, comprenant : - un actionneur comprenant un premier élément, tel qu'une vis, et un deuxième élément, tel qu'un écrou, coopérant avec le premier élément de sorte qu'une rotation du premier élément entraine une translation du deuxième élément, et - une pièce de verrouillage mobile entre une position verrouillée dans laquelle la pièce de verrouillage empêche la rotation du premier élément, et une position déverrouillée dans laquelle la pièce de verrouillage autorise la rotation du premier élément, dans lequel la pièce de verrouillage comprend un verrou (47) ayant une portion convexe (50) et une portion plane ou sensiblement concave (51) aptes à être sélectivement positionnées en regard d'une dent (21) solidaire en rotation du premier élément, pour empêcher ou autoriser la rotation du premier élément.The invention relates to an actuating device for moving a movable cover of a thrust reverser, comprising: - an actuator comprising a first element, such as a screw, and a second element, such as a nut, cooperating with the first element so that a rotation of the first element causes a translation of the second element, and - a movable locking piece between a locked position in which the locking piece prevents rotation of the first element, and an unlocked position in which the locking piece allows the rotation of the first element, in which the locking piece comprises a latch (47) having a convex portion (50) and a flat or substantially concave portion (51) capable of being selectively positioned facing a tooth (21) integral in rotation with the first element, to prevent or allow the rotation of the first element.
