An electromagnetic valve is provided with an elongated tappet guided axially displaceably in a tappet guide, and with a sealing body, embodied on the tappet, that can seal against a sealing seat. So that the valve can be produced more economically yet can be regulated more precisely, the sealing seat and the tappet guide are embodied in one piece. The adjustability of the valve is assured in particular by an adjusting ring.

The invention claimed is: 1. In an electromagnetic valve, for a brake system of a motor vehicle, the valve comprising: an elongated tappet, which is guided axially displaceably in a tappet guide, the tappet having a sealing body embodied on the tappet, the tappet guide having a sealing seat against which the sealing body seals when said valve is in a closed position, wherein the sealing seat and the tappet guide are embodied in one piece; an armature mounted on said tappet at an opposing end from the sealing body of said tappet, and an adjusting device mounted directly on the tappet guide between a lower end face of the armature and the tappet guide, the adjusting device adjusting an air gap which is formed between an upper end face of the adjusting device and the lower end face of the armature, the air gap being adjusted in the axial direction by displacing a mounting position of said adjusting device on said tappet guide and fixing said adjusting device directly to said tappet guide, wherein adjustment of said adjustment device adjusts a stroke length of the tappet. 2. The electromagnetic valve in accordance with claim 1, wherein the tappet is guided displaceably in the tappet guide in such a way that the sealing body strikes the sealing seat centrally. 3. The electromagnetic valve in accordance with claim 1, wherein the adjusting device is an adjusting ring, which is disposed on the tappet guide. 4. The electromagnetic valve in accordance with claim 3, wherein the adjusting device is mounted on the tappet guide by means of a radial compression. 5. The electromagnetic valve in accordance with claim 3, wherein the adjusting device is fixed by means of a laser-welded seam on a substantially cylindrical jacket face of the tappet guide. 6. The electromagnetic valve in accordance with claim 3, further comprising a cap covering the tappet guide and the adjusting ring, and wherein the cap is fixed directly on the adjusting ring by means of a laser-welded seam. 7. The electromagnetic valve in accordance with claim 3, further comprising at least one radial through opening in the tappet guide in the region of the sealing seat though which bore a fluid flowing radially though the sealing seat can be carried away radially to the outside of the tappet guide. 8. The electromagnetic valve in accordance with claim 1, wherein the adjusting device is mounted on the tappet guide by means of a radial compression. 9. The electromagnetic valve in accordance with claim 8, wherein the adjusting device is fixed by means of a laser-welded seam on a substantially cylindrical jacket face of the tappet guide. 10. The electromagnetic valve in accordance with claim 8, further comprising a cap covering the tappet guide and the adjusting device, and wherein the cap is fixed directly on the adjusting device by means of a laser-welded seam. 11. The electromagnetic valve in accordance with claim 8, further comprising at least one radial through opening in the tappet guide in the region of the sealing seat through which bore a fluid flowing radially though the sealing seat can be carried away radially to the outside of the tappet guide. 12. The electromagnetic valve in accordance with claim 1, wherein the adjusting device is fixed by means of a laser-welded seam on a substantially cylindrical jacket face of the tappet guide. 13. The electromagnetic valve in accordance with claim 12, further comprising a cap covering the tappet guide and the adjusting device, and wherein the cap is fixed directly on the adjusting device by means of a laser-welded seam. 14. The electromagnetic valve in accordance with claim 1, further comprising a cap covering the tappet guide and the adjusting device, and wherein the cap is fixed directly on the adjusting device by means of a laser-welded seam. 15. The electromagnetic valve in accordance with claim 1, further comprising at least one radial through opening in the tappet guide in the region of the sealing seat through which bore a fluid flowing radially through the sealing seat can be carried away radially to the outside of the tappet guide.
