Abstract (en)
[origin: EP1106840A2] A hydraulic switching system ha at least two main switching controls (2, 3) each controlled by dedicated control switches and interlinked by AND and OR logic circuits to ensure a rapid switching between the different possible output states. The logic system ensures that if the first system is switched for forward pressure the second system is switched off and vice versa, while, when the first system is switched into the reverse setting the second system can be switched to either setting. The system ensures, for instance, that switching can be rapid without waiting for a lengthy motor reversing sequence.
