摘要： An injection valve for fuel injection systems in internal combustion engines which comprises a movable valve element cooperating with a valve seat disposed in a nozzle body, with a guide bore provided downstream of the valve seat. A swirl insert is partially compressed in the guide bore and disposes open swirl channels in the direction of its circumference. The swirl channels extend in an axial direction from one end of the swirl insert to the other, are slanted toward the longitudinal shaft of the injection valve and discharge in a tangential direction into a preparation bore. The swirl channels serve simultaneously as metering channels whose throttling length is adjustable by displacing the swirl insert inside the guide bore.

摘要翻译： 一种用于内燃机中的燃料喷射系统的喷射阀，包括与设置在喷嘴主体中的阀座配合的可移动阀元件，其具有设置在阀座下游的引导孔。 旋转插入件在导向孔中被部分地压缩，并在其圆周方向上设置开放的旋流通道。 涡流通道从旋转插入件的一端沿轴向方向延伸到另一端，朝向喷射阀的纵向轴线倾斜，并沿切线方向排放到准备孔中。 涡流通道同时作为计量通道，其节流长度可通过使导向孔内的涡流插入件移位来调节。
