<p>The control system is for agricultural vehicles, with one hydraulic power jack, and additional hydraulic consumers, which are supplied from a pressure medium source, and switched-on and-off individually via control slides. The slides are positioned in series in the pressure conduit leading to the consumers, and block the conduit, when one consumer is switched on. A changeover slide is provided, spring-loaded in the direction of closing, which with the switching-off of all consumers, guides the medium flow from the source into the return pipe. When the control slide for the power jack is in a neutral position, the spring-loaded front surface of the changeover slide is connected to the storage container and blocked during all other positions.</p> |
