Hydraulic control circuit for a trailer brake valve

摘要

A hydraulic control circuit for one or more consumers, to have priority of supply, is described such as, for example, for a trailer brake valve, which is supplied by a pump by way of a priority valve, which pump is also used for supplying at least one additional secondary consumer. The supply line for the secondary consumer branches off downstream of the priority valve and a pressure governor, which is actuated by the pressure in the trailer brake line in such a way that, in the event of simultaneous operation of secondary consumer and brake, the pressure governor is modulated in the closing direction, is assigned to each secondary consumer.
