Abstract
Automatic device for the damped closing of doors, essentially characterized by comprising a cylinder in which a rack moves by means of a spring on an end piston thereof, with speed regulated by the pressure of oil in a piston in the another end of the rack, whose rack meshes with an extreme pinion of an elbow lever, which at its free end circulates through a guide so that the speed of rotation of a door can be regulated by applying the guide and the cylinder to each one of the parts of it.
