Abstract
An indirectly-acting, load-dependent compressed-air brake for railway vehicles, having a brake cylinder, to which compressed air can be admitted, as a function of the pay load, by a regulating valve via a compressed-air ratio device, a surge pressure, to overcome the forces of the release spring, being generated when braking is initiated in the brake cylinder, even if the vehicle is empty or only partially loaded, and the compressed-air ratio device having a balance beam which is loaded at one end by the regulating pressure via a piston and is loaded at the other end by the brake cylinder pressure via a second piston and, in the opposite direction, by the regulating pressure via a third piston and by a spring, wherein the second piston can be supported in the load direction of the brake cylinder pressure by an annular piston which is supported by the said spring in the third piston, the stroke of the annular piston in the load direction of the brake cylinder pressure and the stroke of the third piston in the opposite direction being limited by stops.
