摘要 PCT No. PCT/DE98/00080 Sec. 371 Date Nov. 17, 1998 Sec. 102(e) Date Nov. 17, 1998 PCT Filed Jan. 12, 1998 PCT Pub. No. WO98/44256 PCT Pub. Date Oct. 8, 1998A fuel injection valve, particularly an injection valve for fuel injection equipment of internal combustion engines, having a pump piston that can be activated using a piezoelectric or magnetostrictive actuator for exerting a translatory pump motion. A spray-discharge nozzle with at least one spray-discharge opening is hydraulically connected via a fuel pressure line to the pump piston. The spray-discharge nozzle opens when the fuel pressure produced by the pump piston in the fuel pressure line exceeds a predetermined threshold. In the fuel pressure line, at least one non-return valve is arranged so that it opens in the direction towards the spray-discharge nozzle and closes in the opposite direction.
