  • Patent number: 5348047
    Abstract: A valve arrangement comprising a fluid distributor and a signal distributor arranged adjacent to the same. On the fluid distributor a main valve with a control unit is mounted. The signal distributor has a set of upwardly directed plug connectors. Furthermore there is a set of upwardly directed plug connectors on the control unit, which set is however at a higher level than the that of the signal distributor. In order to produce an electrical connection between the control unit and the signal distributor there is an electrical connection bridge, which comprises internal electrical conductors, which connect together two further sets of electrical plug connectors. Since these sets of plug connectors are directed downwards the connection bridge may be plugged in position from above without any difficulty, respectively associated sets of plug connectors entering into a plugged connection with one another.
