Abstract (en)
[origin: WO03040546A1] The invention concerns an injector for high-pressure fuel injection for auto-ignition internal combustion engines, comprising a hollow body (1) provided at one of its ends a valve seat (2) and at least an injection orifice (3). The inventive injector further comprises a needle valve (4) which is arranged in the extension of a valve piston (5) in the injector body (1) and which, when closed, closes at least the injection orifice (3), and at least a spring which maintains the injector closed, when there is no pressure, by pressing the needle valve (4) on the valve seat (2). Said injector comprises at least two magnetic devices for directly opening and closing the injector.
