摘要： Die Erfindung betrifft ein elektromagnetisch betätigbares Ventil mit einer Ventillängsachse (3), mit einem elektromagnetischen Kreis (1, 2), mit einem beweglichen Betätigungsglied (25), das zum Öffnen und Schliessen des Ventils mit einem festen Ventilsitz (23) zusammenwirkt, und mit einer stromabwärts des Ventilsitzes (23) ausgebildeten Auslassöffnung (8). Das Betätigungsglied (25) ist schalen-, trog- bzw. napfförmig mit einem Betätigungsschenkel (26) und einem weitgehend dazu senkrecht ausgebildeten Abstützschenkel (27) ausgeführt. Der Betätigungsschenkel (26) wirkt als der bewegliche Teil des Betätigungsgliedes (25) mit einer oberen Lage (15) einer Zerstäuberscheibe (12) zu einem Dichtventil zusammen. Das Ventil eignet sich besonders für den Einsatz als Brennstoffeinspritzventil in einer Brennkraftmaschine, insbesondere in einer gemischverdichtenden, fremdgezündeten Brennkraftmaschine.

摘要： The invention relates to a helical compression spring (40) for use in a structural member of a fuel injection system, for example a structural element in the form of a fuel injection valve (1). Said helical compression spring (40) has a spring wire cross-section corresponding to a rectangle with rounded edges and an inner surface (46) constituting the interior of the helical compression spring (40) that is strongly cambered. Said cross-section contour of the spring wire reduces the shearing strain when the helical compression spring (40) is subjected to stress, thereby allowing to reduce the length of the helical compression spring while maintaining the same spring rate (K). The lateral surfaces (42) of the spring wire facing each other in the helical compression spring are at least approximately parallel so that they flatly rest against each other at the ends of the helical compression spring (40) due the helix height (H) that is reduced in said area, thereby avoiding a decrease of the spring force when the helical compression spring (40) is prestressed.

摘要： The invention relates to an electromagnetically actuated valve comprising a valve longitudinal axis (3), an electromagnetic circuit (1, 2), a displaceable actuating member (25), which co-operates with a fixed valve seat (23) to open and close the valve and with an outlet opening (8) that is configured downstream of the valve seat (23). The actuating member (25) is cup, trough or bowl-shaped and comprises an actuating limb (26) and a supporting limb (27) that is configured in a substantially perpendicular manner in relation to the actuating limb. The actuating limb (26) acts as the displaceable part of the actuating member (25) and co-operates with an upper layer (15) of an atomiser disc (12) to form a sealed valve. The valve is particularly suitable for use as a fuel-injection valve in an internal combustion engine, in particular in a compressed-mixture, spark-ignition internal combustion engine.
