LOAD-DEPENDING PNEUMATIC BRAKE WITH INDIRECT EFFECT

Indirectly acting, load-dependent compressed air brake, especially for railways, with a brake cylinder, which can be charged with compressed air by a control valve via a compressed air converter depending on the payload of the compressed air vehicle, in which, when the brake is put into operation, a release or delivery pressure is generated in the brake cylinder, even when the vehicle is empty or only partially loaded to overcome the forces of the recovery spring, and the air converter compressed has a rocker arm, which is loaded at one end through a piston, by the control pressure and at the other end, through a second piston, by the pressure of the brake cylinder, and in the opposite direction, to through a third piston, by the control pressure and by a spring, characterized in that the second piston charged by the pressure of the brake cylinder, can be supported in the direction load pressure of the brake cylinder pressure on an annular piston, which is supported by the aforementioned spring on the third piston, and because the stroke of the annular piston is limited by a stop in the direction of load cylinder pressure of brake and the race of the third piston is by another stop in the opposite direction.
