Abstract

A fuel injection valve (1) which serves as an injector for fuel injection systems of air-compressing, auto-ignition internal combustion engines has an actuating device (20) which is arranged in a valve housing (3) and a valve closing body (30) which can be actuated by the actuating device (20) by means of a hydraulic coupler (13). Here, the hydraulic coupler (13) has a coupler space which is connected to a fuel inlet stub (10) via a first fuel channel (11) and to a fuel space (15) by way of a second fuel channel (14). Here, the fuel channels (11, 14) open into the coupler space (12) on flat opening faces (42, 43), as a result of which high strength is ensured. In particular, there is an intersection-free transition.
