ABSTRACT:
A fuel injection valve for internal combustion engines with an injection port disk disposed in a longitudinal opening of a valve housing, which prevents deposits from forming due to evaporation of the fuel remaining at the injection ports after the engine is switched off. A gap disk is therefore disposed downstream of the injection port disk in the longitudinal opening of the valve housing with a slight axial spacing; the gap disk defines a recess in the axial direction which exerts a capillary action outward in the radial direction upon the fuel emerging at the injection ports. By disposing a capillary disk between the injection port disk and the gap disk, the capillary action can be optimized by means of corresponding contours in the capillary disk. The fuel injection valve is particularly suited for fuel injection in mixture-compressing engines with externally supplied ignition.
