Abstract

A fuel injection valve for internal combustion engines, having a holder body, which can be braced with a valve body that protrudes into the engine combustion chamber. A fuel inflow conduit extending from one end is provided that is formed by a longitudinal bore and a transverse bore that intersects the longitudinal bore. The injection port of the transverse bore forms a lateral pressure connection on a radial circumferential wall of the holder body for a fuel delivery line. In the region of a radial circumferential wall face opposite the lateral pressure connection, the holder body has a radially inward-pointing flat face.
