ABSTRACT:
A fuel injection valve has a fuel filter developed as one piece with a holding collar. The holding collar extends radially beyond the fuel inlet connection and has a nose outside the fuel inlet connection. The circumferential nose of the holding collar together with the groove on the outer circumference of the fuel inlet connection forms a detent connection by which the fuel filter is fastened in pin-pointed position. Between the base body of the fuel filter and the inner wall of the fuel inlet connection there is merely a clearance fit, so that formation of chips is avoided within the fuel injection valve. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing external-ignition internal combustion engines.
