摘要:
The invention relates to a valve arrangement with a pressure limiting valve and a flow regulator valve, which comprises a flow regulator piston, having at least one first hydraulic resistor, distinguished in that the flow regulator valve's (5) flow regulator piston (15) has a split pressure return surface and in that the first part (ring surface (45)) of the pressure return surface is capable of working at a pressure p1 and a second part (annulus surface (31)) of the pressure return surface is capable of working at a pressure p2.
