Abstract (en)
[origin: EP0205925A2] The control device has a proportional directional valve (13) for a consuming device (20) as well as a proportionally working control valve (27) for an adjustable pump (10). The valves are adjusted in proportion to an input desired value by an electronic regulating device (32). In this way, a simple adjusting device is obtained which avoids long linkages and hydraulic lines. Through a simple auxiliary member, it is possible to give the pump adjustment an advance over the consuming device. In addition, it is possible to feed the speed of the power equipment into the control device, as a result of which the saving in energy becomes particularly great. <IMAGE>
