<p>A switching valve (2), which serves in particular as a magnet valve for injection valves of air-compressing, self-igniting combustion engines, has a valve piece (3), on which a valve seat (4) is formed, and a valve closing body (5), which interacts with the valve seat (4) to form a sealing seat. Thereby, the valve piece (3) comprises a guiding section (26), on which the valve closing body (5) is guided with a guiding opening (27). Further, the valve piece (3) has ducts (32, 33), extending into a space (29) between the guiding section (26) and the sealing seat. Hereby, a sealing seat having a diameter (34) of, e.g., 1.8 mm can be realized.</p> |
