Abstract (en)
The invention refers to a geared linear actuator, particularly well-suited for operating windows, repositioning dish-type radio antennae and optical units, for operating valves, repositioning solar panels and so on. According to this invention, the actuator has an elongated prism-shaped housing (10) in which a hollow rod (22) slides, passing through one of the ends (18) of the housing and secured to the window to be operated. Said hollow rod (22) is internally threaded and is screws to an externally threaded coaxial rod (40), the rotation of which is controlled by an electric motor (20).
