The invention relates to an actuating device comprising: &#x2014;a first element (), &#x2014;a second element () able to move translationally with respect to the first element (), and &#x2014;a locking device () comprising a catch () able to move between a deployed position and a retracted position, the catch (-) being positioned with respect to the first element () in such a way that when the catch (-) is in a deployed position, the catch (-) allows the second element () to move with respect to the first element () in a first range of movement (A) and prevents the second element () from moving with respect to the first element () in a second range of movement (B), and when the catch (-) is in the retracted position, the catch (-) allows the second element to move with respect to the first element () in the second range of movement (B). This device is particularly suited to allowing actuation of a thrust reverser system and of a system that regulates air flow through an aircraft propulsion unit.

Actuating device including a primary locking device

The invention concerns an actuating device () for moving a mobile cover of a thrust reverser, comprising: an actuator () comprising a first element (), such as a screw, and a second element (), such as a nut, mounted mobile device relative to the first element () such that the rotation of the first element () results in a translational movement of the second element () relative to the first element (), and a locking device () comprising a rotating part () linked in rotation with the first element (), and a locking part () that is mobile relative to the rotating part () between a locked position in which the locking part () is engaged with the rotating part () to prevent the first element () from rotating and an unlocked position in which the locking part () is disengaged from the rotating part to allow the rotation of the first element (), and an electromagnet () for moving the locking part () to the unlocked position.

Actuating device for moving a thrust reverser

The invention relates to an actuation device () for moving the movable cowling of a thrust reverser, comprising: an actuator () with a first member () such as a screw, and a second member () 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 () including a locking part () 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 () comprising a recess () and a ball () 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.
