Abstract (en)

[origin: EP2594523A1] The platform has application lines (16, 17) with connections connected to respective sides of a volumetric flow control valve (11) e.g. 2-way volumetric flow control valve. An orifice plate (14) is provided in pressure lines (4, 5) between a drive machine (2) i.e. pump, and the valve. An actuating element (15) i.e. electrical coil, changes a position of the plate. A pressure sensor (18) delivers a signal to the actuating element of the plate proportional to a measured hydraulic pressure. A working machine (1) i.e. hydraulic cylinder, is connected with the drive machine.
