A control valve with a control slider (9) comprising bead-type areas (17, 18, 19), by means of which the control slider is slidably arranged in the cylinder bore (8). The areas (17) and (18) isolate the inlet (2) from the outlet (3), while the area (19) isolates the outlet (3) from the leakage oil port (4). The clearance between the areas (17) and (18) of the control slider (9) and the wall of the cylinder bore (8) is smaller than the clearance between the area (19) of the control slider (9) and the wall of the cylinder bore (8). The output pressure is kept within close tolerances with only minor leakage losses.
