TLDR
In this article, a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine is described, and a slit-type flow outlet is formed between the slit-forming element and a front face of the valve seat body.Abstract:
The invention relates to a fuel-injection valve, in particular a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine. Said valve is characterised in that an outlet opening (23) is provided downstream of the valve seat (20), the downstream end of said opening having a slit-forming element (30) that to a great extent closes the outlet opening (23). A slit-type flow outlet (35), through which a fuel spray can be discharged in a fan-type jet, is formed between the slit-forming element (30) and a front face (34) of the valve seat body (16).read more

Low mass, through flow armature
TL;DR: In this article, the impact minimization means (30) are provided to minimize the effect of such impact forces, and the impact-minimization means comprises on the armature (20) multi-dimensional fluid passages through the armatures that minimizes the effect in comparison to the impact forces in the absence of the multidimensional fluid passages, where the one side of the Armature causes impact forces to be exerted axially on the stator during the opening and closing of the flow path.
