DRIVING DEVICE FOR MOVING MOVABLE HOOD OF THRUST REVERSE Russian patent published in 2017 - IPC F02K1/76 

FIELD: transportation.

SUBSTANCE: driving device for moving a movable hood of a thrust reverse comprises a drive, a locking device, and a locking retention device. The drive includes a first element and a second element mounted movably relative to the first element. One of the first or the second element is a screw, and the other is a nut made with the possibility to interact with the screw, so that the rotation of the first element relative to the second element results in the translational movement of the second element relative to the first element. The locking device comprises a locking part and a drive mechanism. The locking part is made rotatable relative to the first element between the locked position, in which the locking part prevents the rotation of the first element, and the unlocked position, in which the locking part provides the rotation of the first element. The drive mechanism is configured to rotate the locking part into the unlocked position. The locking retention device comprises a retaining piece configured to be progressively moved relative to the first element between the first and the second position. In the first position, the retaining piece provides the rotation of the locking part between the locked position and the unlocked position. In the second position, the retaining piece prevents the locking part from rotating into the locked position.

EFFECT: invention allows to reduce the dimensions of the locking device and to reduce its sensitivity to sharp accelerations.
