    • Telescopic actuator comprising: - an actuator body (9); - a sleeve (40) with a longitudinal axis (Y) mounted such as to rotate and extending at least partially into the body, said sleeve being held in axial position in the body by attachment means; - a threaded rod mounted such as to slide telescopically in the longitudinal axis (X) inside the sleeve (40) and engaging with the sleeve (40) by means of a helical link; - rotating means suitable for rotating the sleeve (40) such as to slide the threaded rod selectively between an extended position and a retracted position; - locking means suitable for making the retraction of the helical link irreversible, such that a retraction of the threaded rod caused by a compression load is prevented when such a retraction is not caused by the driving means. Aircraft engine comprising at least one such actuator.
    • 伸缩致动器包括:致动器本体(9); - 安装有纵向轴线(Y)的套筒(40),以便至少部分地旋转并延伸到所述主体中,所述套筒通过附接装置保持在主体中的轴向位置; - 安装的螺杆,其可以在套筒(40)内部的纵向轴线(X)上可伸缩地滑动并且通过螺旋连接件与套筒(40)接合; - 适于旋转套筒(40)的旋转装置,以便在延伸位置和缩回位置之间选择性地滑动螺杆; - 锁定装置适于使螺旋连杆的缩回不可逆,使得当这种收缩不是由驱动装置引起时,防止由压缩载荷引起的螺纹杆的缩回。 包括至少一个这样的致动器的飞机发动机。
