Abstract: The invention relates to a radial piston pump, comprising an inlet chamber with an inlet connection, an eccentric which may be driven in a rotating manner, arranged within the inlet chamber, for driving at least one piston of the radial piston pump, a cylinder bore for guiding the piston and an inlet controller, which opens and closes a connection between the inlet chamber and the cylinder bore, depending on the piston position. The radial piston pump is characterized by at least one balancing element (24, 25) for the eccentric (17), which rotates synchronously with the eccentric (17) in the inlet chamber (20), the balancing element (24, 25) being so arranged in the inlet chamber (20) and/or so formed in its contour that a hydraulic resistance is formed between the inlet connection (8′) and inlet controller (31), or the flow of medium reaching the inlet controller (31) is unaffected.

Abstract: 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.
