ABSTRACT:
A dual circuit brake valve which is provided with a relief connection intended for two separate individual valves and in which two outlet valve seats are disposed centrally in the valve. The two outlet valve seats are prestressed with respect to one another by way of a bolt and a prestressed pressure-limiting spring in such a way that at a time braking begins the two individual valves represent a rigid connection. From a pressure limitation point on, the two individual valves then support themselves elastically against one another, so that a further increase in braking pressure is precluded. The dual circuit brake valve is intended for brake systems having high pressure as a reservoir pressure and normal pressure as the braking pressure.
