Abstract: A device, consisting of at least one control piston (12) which is longitudinally displaceable in a housing (10) comprising at least two connection points (P, A) for fluid, and which cooperates with a metering edge (34) of the housing (10) at a connection point (P), said point, in control positions of the control piston (12), supplying the other connection point (A) with fluid via a fluid connection, and which piston, as a result of occurring flow forces, tends to be drawn in the direction of a closing position which blocks one of these fluid connections. The device is characterized in that in order to compensate the flow force, the control piston (12) has, in the region of the control edge (34) of the housing (10), a shape modification (48) of its cylindrical exterior basic form (50), such that a flow contact surface (52) for fluid is created, which surface transfers a compensating force that acts against the flow force to the control piston (12) and that seeks to pull the control piston (12) into an opening position opposed to the closing position.
