ABSTRACT:
A fuel injection nozzle for internal combustion engines having a filter body inserted into the fuel inflow conduit, an injection valve and a check valve, which maintains a static pressure in the injection nozzle and can also perform a relief function for the prevention of after-injections. The check valve is integrated into the filter body thereby simplifying the final assembly of the injection nozzle. The filter body is advantageously embodied as a rod-type filter, which by the appropriate shaping of its jacket periphery forms gap-like spaces between itself and the surrounding wall of the nozzle holder through which spaces the fuel must pass such that it is deflected multiple times.
