Abstract
Improvements in the system of door closers for doors that open on one side, whose system consists of a box arranged movable in another mounting box and closed by a cover and with a tension spring housed therein together with a braking device formed by plunger and cylinder, attacking both by means of a transmission of four articulations on a crank axis joined with the door characterized in that when the door is closed they are located at least approximately on one line, the centers of the crank axis (11) of the second fixed articulated shaft (18) of the transmission of four articulations and of the articulation of the spring (20) and the central line of the crank of the shaft (11) forms with this line an acute angle.
