摘要： A fuel injection valve having a valve retaining body, which has a longitudinal axis and in which a central spring chamber is embodied. In this spring chamber, a closing spring is disposed, which transmits a closing force to a valve member, which valve member cooperates with a valve seat for controlling at least one injection opening. In the wall of the spring chamber, an inlet conduit extends parallel to the longitudinal axis of the valve retaining body, and by way of this conduit, fuel at high pressure can be delivered to the at least one injection opening. The cross section of the inlet conduit has a greater length in the circumferential direction than in the radial direction, so that the wall region between the inlet conduit and the spring chamber, or the outer jacket face of the valve retaining body, is larger than in the case of an inlet conduit with the same size of cross-sectional area and a circular cross-sectional contour.

摘要： 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.
