Document Type and Number:
WIPO Patent Application WO2002031343
Kind Code:
A3
Abstract:
The invention relates to a fuel injection valve (1) for fuel injection systems of internal combustion engines. Said fuel injection valve comprises a valve closing element (4) that is functionally linked with a valve needle (3) and that interacts with a valve face (6) of a valve seat (5) to give a sealing seat. The valve is further provided with a swirl-producing element that is located downstream of the sealing seat in the valve seat (5) and whose center axis (38) preferably includes an angle different from zero with the center axis (39) of the fuel injection valve (1). The swirl-producing element is a threaded rod (36) that is press-fitted into the valve seat (5).
