Abstract
A brake arrangement of a railway vehicle includes an electrical brake device having an electronic brake controller and having an electro-pneumatic regulator with a pressure sensor. An emergency brake device has a pressure reducer in series with a valve device. A shuttle valve device is also present at a pneumatic output of the electrical pneumatic braking device and a pneumatic output of the emergency brake system and is connected at the inputs thereof. The output of the valve device is connected to a control valve device connected upstream of a brake cylinder. The brake arrangement can be a direct braking arrangement and can be converted in a simple manner to an indirect braking arrangement. The valve device is an electromagnetic emergency stop valve working according to the principle of de-energizing to close, and the pressure sensor of the electro-pneumatic regulator is connected to the output of the shuttle valve device.
