Abstract (en)
A linear actuator (1) for actuating the feed device (204) of a parabolic antenna in relation to the reflector (202), to permit reception from variously located satellites. The actuator (1) comprises a cylindrical casing (3) housing an electric motor (5) for powering a screw (9) housed in a tubular body (7) extending axially from one end of the casing (3). The screw (9) is fitted with a slide (98) housed in the tubular body (7) and presenting a recirculating-ball nut screw (114) connected to the screw (9); and the slide (98) is also connected to a support (120) projecting from the tubular body (7) and supporting the feed device (204). <IMAGE> <IMAGE>
