Abstract:
A guide apparatus for supports (20) for sensors (30) able to move by translation in fixed guides (10) integral with the sail (Ia) of submarines (1) and the like upon activation of an actuator (40), where the fixed guide (10) has a polygonal cross-section, at each vertex (10b) of the guide (10) there being at least one structure with the shape of a prism (11) extending in the vertical direction (Z - Z) along the entire body of the guide, the prismatic elements (11) extending towards the inside of the guide (10) in such a way as to form at least two sliding surfaces (12) for corresponding sliding blocks (22) belonging to the tube (20) to be moved by translation.
Abstract:
Apparatus for moving tubes (10) which are displaceable upon operation of an actuator (40) inside fixed guides (20) integral with the tower (1a) of submarines (1) and the like, said actuator (40) consisting of at least one pair of linear motors (41).
Abstract:
Device for moving in the longitudinal direction (X-X) a shaft (120;1120;2120) with screw (121) rotationally driven by a motor (140;2140), comprising at least one cylinder (100;1100;2100) coaxial with said shaft (120;1120;2120) and provided with at least one rotating piston (131;1131;2131) rigidly connected to the shaft (120;1120;2120) and able to produce a displacement in either direction of the shaft (120;1120;2120) from a first retracted end-of-travel position into a second advanced end-of-travel position, and vice versa.
