A fuel injector for diesel engines, having at least one pump plunger (1), which is sealingly guided in a plunger bushing (2) and, together with said bushing, defines a high-pressure space (5). The pump plunger (1) has an internal suction valve (6) which creates a fuel injection pump having a small dead volume in the high-pressure region and low construction cost. The suction valve (6) may be provided with a cone-shaped compression spring (7) disposed in the high-pressure region (5) or with a stroke limiting stop (28, 28a).
