Abstract:
An edge filter for a fuel injection nozzle is provided with an improved connection to the stem of the nozzle. The connection comprises opposed cylindrical guide sectors on the filter having axial knurls that extend less than the full length of the guide sectors thereon. The knurls, which are case hardened, provide secure interference interengagement with the softer counterbore of the nozzle's fuel inlet stem. The guide sectors advantageously provide an edge filtering function as well as a guiding function.
