Abstract (en)
[origin: WO2009062572A1] The invention relates to a hydraulic valve device comprising a fluid connection arrangement (10) having different types of connections, and a mobile control device (18) for at least partially controlling connections of the fluid connection arrangement (10). As the control device (18) is provided with load reporting and load detecting connections (32,34; 36,38) that are interconnected and thereby associate a load reporting connection with a detection connection (32,38; 34,36), and, according to the displacement position of the control device (18), interconnect at least one part of the connections of the fluid connection arrangement (10) in a fluid-guiding manner, the control device can be brought with precision into the required functional positions, with a favourable dynamic driving behaviour.
