摘要 |
<p>The invention provides a fuel injection pump for internal combustion engines having a high-pressure chamber, which is intermittently brought to high fuel pressure, and which communicates via a pressure line with an injection point of an engine, and having a pressure valve, inserted into the pressure line. This pressure valve comprises a valve body and a valve seat onto which a valve member is pressed by the force of a valve spring. The valve spring is located in a recess of a pressure valve holder, which communicates with the injection line via an axial conduit. A transitional region leading from the diameter of the axial recess to the diameter of the conduit is embodied with a cone shape or a truncated cone shape.</p> |
