| 摘要 |
The invention relates to a fuel injection valve, especially injection valve for fuel injection systems of internal combustion engines, comprising an actuator which interacts with a valve needle (34, 51, 73). The fuel injection valve has a first valve closing body (35, 52) which is located on the valve needle (34, 51, 73). Said valve closing body interacts with a first valve seat surface (33, 53) on a valve seat body (32, 50) to form a first sealed seat (36, 54). A second valve closing body (38, 55, 75) interacts with a second valve seat surface (40, 56) in the valve seat body (32, 50) to form a second sealed seat (41, 57). The valve needle (34, 51, 73) or the first valve closing body (35, 52) has a stop which a counter-stop of the second valve closing body (38, 55, 75) strikes after a partial stroke (h1) of the valve needle (34, 51, 73), raising the second valve closing body (38, 55, 75) from the second sealed seat (41, 57) on the next stroke of the valve needle (34, 51, 73).
