Abstract (en)
[origin: EP1710446A2] The arrangement has a continuous adjustable solenoid valve arrangement with a forward motion valve gate to adjust a pressurizing medium flow rate to a load. A reverse motion cross section is adjustable for the flow rate diverting from the load by the reverse motion valve gate. Pump side of valve gates upstream a common individual pressure scale, over which pressurizing medium flows to an inlet orifice controlled by one of the gates. An independent claim is also included for a control block for controlling several loads.
