Abstract
The invention relates to a torque limiter for an actuator including a screw (101), a nut mounted on said screw, an actuation tube (105) rigidly connected to the nut and means (109, 133) for rotating said screw, said limiter being characterized in that it includes an abutment (115, 110) capable of: preventing the rotation of said tube (105) by friction simply by an axial force exerted by said screw (101) onto said nut during the movement thereof; and enabling the rotation of said tube (105) when said nut arrives at an axial abutment of said screw beyond a predetermined torque threshold defined by the axial force.
