摘要

A system of automotive hinges, moved with pneumatic energy, designed to open and close barracks or folding pontoons of the hatches of ships and similar services, capable of forcing the pontoons to turn from 0º to 360º, characterized in that the engine pneumatic is formed by a central cylindrical body divided into four or more cylinders half of which work to one side and the other half in the opposite direction, because the pistons of these cylinders of the same direction are joined together by a common shank, because the common shank is extended by another shank which has two longitudinal channels carved that prevent the pistons from turning on their longitudinal axis, because the end of the extended shank carries a transverse bolt provided on their heads with two bearings intended to transform the rectilinear movement of the pneumatic pistons in circular motion, because the movement circulates r is achieved by a path carved inside a rotating sleeve in the form of helical or spiral curve where the two bearings located in the heads of the transverse bolt move and because the rotating jackets are attached to the body with the interposition of crowns of Axial and radial bearings that minimize the passive resistance.
