摘要:
The invention relates to a control valve for a fuel injector, in particular a common-rail fuel injector, comprising a valve piece (1) having an outflow opening (3) which is formed inside a valve seat (2) formed as a flat seat, and a reciprocating valve-closing element (4) which interacts in a seal-forming fashion with the valve seat (2). According to the invention, the outflow opening (3) is embodied in a slit shape and has a length (L) which is greater than a width (B), wherein the length (L) corresponds essentially to a diameter (D) or a radius (R) of a circular surface (5), within which the outflow opening (3) and at least one further outflow opening (6, 6') which is connected to the outflow opening (3) and/or separated from the outflow opening (3) are arranged. The invention also relates to a fuel injector having a control valve of said type.
摘要(中):
本发明涉及一种用于燃料喷射器的控制阀,特别是共轨燃料喷射器,其包括具有流出开口(3)的阀片(1),该流道开口形成在形成为平座的阀座 ,以及以密封形成方式与阀座(2)相互作用的往复式阀关闭元件(4)。 根据本发明,流出口(3)实施为狭缝形状,并且具有大于宽度(B)的长度(L),其中长度(L)基本上对应于直径(D)或 圆形表面(5)的半径(R),流出开口(3)和连接到流出开口(3)的至少一个另外的流出开口(6,6')和/或与流出物分离的至少一个另外的流出开口 打开(3)。 本发明还涉及具有所述类型的控制阀的燃料喷射器。
