Abstract
The invention relates to an actuation device (1) for moving the movable cowling of a thrust reverser, comprising: an actuator (7) with a first member (12) such as a screw, and a second member (14) such as a nut, wherein the first and second members are capable of engaging such that the rotation of the first member results in a translation of the second member, a locking device (33) including a locking part (34) movable between a locked position for preventing to the rotation of the first member and an unlocked position for enabling the rotation of the first member, and a lock inhibiting device (42) comprising a recess (46) and a ball (47) movable in the recess between a stowed position, in which the ball enables the movement of the locking part, and an inhibition position in which the ball prevents the locking part from returning into the locked position.
