Abstract:
PCT No. PCT/DE96/01480 Sec. 371 Date Oct. 10, 1997 Sec. 102(e) Date Oct. 10, 1997 PCT Filed Aug. 8, 1996 PCT Pub. No. WO97/22801 PCT Pub. Date Jun. 26, 1997A fuel injection valve for internal combustion engines having, a valve member, which is axially displaceable in a valve body and which on one end has a valve sealing face with which it cooperates with a stationary valve seat in order to control an injection cross section, and having at least one valve spring, which urges the valve member in the direction of the valve seat and is braced on its other end on a stationary stop. To increase the spring force of the valve spring while the outer diameter remains the same, the windings of the valve spring, embodied as a helical spring, have a circular basic cross section (Y), which in a region pointing radially outward from the axis (X) of the valve spring has a ground face oriented parallel to the spring axis (X).
