| 摘要 |
<p>The invention concerns an electromagnetically operated fuel-injection valve (1) for internal-combustion engines. The operation and wear characteristics of the valve are improved by virtue of the fact that a stroke-limiting plate (21) is located between the armature (15) and the stop surface (16) thus defining the distance between them. Mounted on the stop-surface side of the plate (21) is a support plate (27) which is acted on by a spring (29). The support plate (27) has a curved surface (25) which is seated on a matching inner, curved surface (23) on the stroke-limiting plate (21). The matching inner, curved surface (23) extends outwards into an outer, annular surface (22) which abuts the stop surface (16). The other, curved, side (19) of the stroke-limiting plate (21) rests on a matching surface (17) of the armature (15). The invention is intended in particular for motor vehicles.</p> |
