It is proposed, in the case of a hydraulic component having a closure part 11 which blocks off or restricts a channel 5 and against which bears in the closing direction at least one compression spring 17 at whose end opposite the closure part 11 a manually operable spring force-adjusting device is arranged, to connect in series between the spring force-adjusting device and the compression spring 17 a further spring force-adjusting device which can be subjected to controlling pressure and whose adjusting path is limited by an adjustable stop. The first spring force-adjusting device is preferably designed as a hollow screw 20 in whose interior the stop constructed as a regulating screw 21 and a supply channel for the controlling-pressure medium are provided. The screw head 22 of the regulating screw 21 is hung into an axial undercut recess of the second spring force-adjusting device constructed as a piston 18. It is thus possible to open the closure part at various selectable counterpressures in the channel. <IMAGE>
