| 摘要 |
<p>The invention relates to a fuel injection valve (1), especially an injection valve for fuel injection systems of internal combustion engines, which has a piezoelectric or magnetostrictive actuator (4) and is provided with a valve closing body (15) in a valve housing (2). Said body can be actuated by the actuator (4) by means of a valve needle (13). The valve closing body (15) engages with a valve seat-face (16) to form a sealed seat. The actuator (4) rests against a first front face (23) on a a first actuator housing component (6) and against a second front face (24) on a actuator housing lid (8) which is configured on a second actuator housing component (7). Segments (20) of the second actuator housing component (7) are distributed over the circumference of the valve and act upon the valve needle (13) via a closing plate (19). The actuator housing lid (8) is sealed against the first actuator housing component (6).</p> |
