Abstract
A single-chamber self-locking cylinder is described in which the single-chamber is made up of a male half-cylinder and a female half-cylinder that are inserted one into the other in mutually sliding way in axial direction. Two pairs of diametral rods that are angularly offset from each other are provided that operate on said half-cylinders in order to retain them in a predetermined axially centred position under the action of a fluid in pressure that is fed inside said single-chamber. Each one of said pairs of diametral rods is made up of two rods operating onto opposite faces of said half-cylinders and coupled to each other by axial tie rods. One of the two rods is fastened to a stem coupled in axially sliding way to one of the two half-cylinders while the other one is slidingly coupled to another stem that is coupled in axially sliding way to the other one of the two half-cylinders.
