Abstract
Shock absorber for automatic closing of doors and the like, characterized in that the arm of the shock absorber rotates the vertical axis of a toothed pinion meshing with a rack, the ends of which are integral with two piston heads. One of them is movable in a cylinder with hydraulic load, whose damping action determines that, when verifying the closing, the speed is slower. In the head of the piston mounted on the other end of the rack, the head of the return spring acts, which is compressed when the door is opened. At the free end of the spring, it acts on a hydraulic piston linked to the one of the rack. Thus, when free the extension of the spring moves the rack in the opposite direction, first quickly and then more slowly when the hydraulic device acts.
