Abstract (en)
[origin: WO2008077657A1] The invention relates to a fuel injector with an injector housing (1) which has a high-pressure fuel connection which is connected to a central high-pressure fuel source (28) outside the injector housing (1) and with a pressure space (17) within the injector housing (1). According to the pressure in a coupling space, fuel under a high pressure is injected from the pressure space (17) into a combustion space of an internal combustion engine when a nozzle valve (8) opens which has a combustion space-remote end (45) with a control pressure surface (61) which is acted upon in the coupling space by the coupling space pressure. In order to create a fuel injector which can be produced inexpensively, the nozzle valve (8) has at least one low-pressure surface (50) which is averted from the combustion space and acted upon with low pressure.
