ABSTRACT:
In the case of a distributor module for valve clusters, which possess a principal valve supplied with pressure medium by way of a supply duct and at least one pilot control valve, serving for controlling same and supplied by way of at least one pilot control supply duct with pilot control pressure medium, the distributor module has a supply duct section and two pilot supply duct sections, which are able to be coupled with the supply duct or, respectively, with a respective pilot control duct of the valve cluster, an interface for the connection of the duct sections with each other, with which a control element is associated, which is so designed that different switching conditions may be set, in which the supply duct section and the pilot supply duct sections are differently put in circuit with each other. At least one first switching condition may be set, in the case of which the two pilot supply duct sections are connected together in circuit and simultaneously are separated from the supply duct section or at least one second switching condition may be set, in the case of which all duct sections of the distributor module are put in circuit with each other.
