Abstract
An electropneumatic device for a pneumatic braking system, including a compressed air reservoir for providing a reservoir pressure; a brake pressure modulator which receives reservoir pressure and outputs a brake pressure at a brake pressure connection in a manner dependent on electronic braking request signals; a protective valve unit with a protective valve inlet, a first protective outlet and a second protective outlet; the protective valve inlet receiving the brake pressure which it can provide at the first and second protective outlets; a first and a second pressure line; and, a brake actuator that is connected to the pressure lines. The protective valve unit is configured to throttle the brake pressure output at the first protective outlet in the event of leakage of the first pressure line and to throttle the brake pressure output at the second protective outlet in the event of leakage of the second pressure line.
