Abstract (en)
[origin: WO2006117259A1] The invention relates to a fuel injection valve with a housing (1) that comprises a valve body (3) with at least one injection opening (18). The outer cylindrical surface of the valve body (3) is essentially configured in a rotational symmetrical manner and has a first cylindrical section (103) followed by a second cylindrical section (203) of the outer cylindrical surface, said second cylindrical section facing the injection openings (18) and having a smaller diameter than the first cylindrical section (103), thereby forming a valve shoulder (30). A recess (35) is formed at the transfer of the valve shoulder (30) to the second cylindrical section (203). In addition or optionally, an annular groove (50; 50') can be formed at the inner or outer surface of the second cylindrical section (203).
