Abstract (en)
[origin: EP1688611A2] The injector has a needle pressure boosting piston (32) with a control piston (34) axially guided in a cylindrical chamber. Coupler and differential chamber pressure surfaces are exposed to coupler and inner differential pressure chambers, respectively. The piston (32) is associated with an outer differential pressure chamber that communicates via a hydraulic connection with the inner chamber acting on the piston (34).
