Abstract:
1. An electropneumatic brake system of a rail vehicle, containing a direct action electropneumatic braking device and an indirect action compressed-air braking device, and further comprising: a) a pressure regulator which produces a pilot control pressure (C b) a pressure limiting valve which limits the pilot control pressure (C c) a control valve which generates a pilot control pressure (C d) a selection device which transmits, from the maximum pilot control pressure of the direct brake (C wherein the selection device is formed by a piston arrangement and/or diaphragm arrangement, having a first active surface which is connected axially fixed to a first piston rod, and a second active surface which transmits force only in one direction to the first piston rod, a first pressure chamber which is subjected to the pilot control pressure (C
