Abstract
A pressure-medium brake system, which comprises multiple circuits and has associated with each brake cylinder or group of brake cylinders relay valves which are controllable by a control medium. Depending on the number of brake circuits and the kind of the respective control medium, the relay valves are provided with several, possibly different, control chambers. This results in an overlapping control which insures that each relay valve can even be controlled in the event that a control circuit has been lost. The brake system is preferably used in utility vehicles equipped with air brakes.
