Abstract (en)
[origin: DE19631280A1] The invention concerns a fuel injection valve for fuel injection systems of internal combustion engines. The fuel injection valve is composed of two main components: an inner valve part (70) comprises all the individual components lying directly in the fuel flow path, whilst an outer plastics part (60) is formed predominantly by a magnet coil subassembly and a plastics casing (50). The valve part (70) comprises inter alia a thin-walled non-magnetic sleeve (18) which is highly sensitive to mechanical and thermal influences. The valve part (70) is therefore produced and adjusted separately from the plastics part (60). The complete valve part (70) is subsequently inserted into a through-hole (54) in the plastics part (60), a fixed connection between the plastics part (60) and valve part (70) being brought about by engagement, locking or clipping in place. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.
