Abstract

There is disclosed a pressure-regulating valve which serves to control friction brakes dependent on the braking effect of a hydrodynamic brake. In order to achieve a full pressure decrease in the friction brakes, these are connected to an unpressurized reservoir while the hydrodynamic brake is operating at full effect.
