VERFAHREN ZUR MONTAGE EINES FILTERS AN EINEM VENTIL UND VENTIL

摘要

In known valves, a filter element composed of plastic and having a filter fabric is pushed onto the circumference of a valve body provided with passage openings and there is the risk that the interior of the valve will be contaminated by plastic material of the filter element during the process of pushing on. …In the method according to the invention, for mounting a filter on a valve, the filter fabric (35) is arranged in such a way on the circumference of a valve body (5) that the filter fabric (35) covers the passage openings (7) of the valve body (5). The valve body (5) is then provided with a plastic encapsulation (39) in order to fix the filter fabric (35) in its position relative to the through openings (7). In this way, contamination of the interior of the valve by plastic particles is avoided. …The method according to the invention is suitable particularly for fuel injection valves for fuel injection systems of internal combustion engines. ……
