摘要：
The invention relates to an injector for injecting fuel into combustion chambers of internal combustion engines. According to the invention, a valve seat of a control valve is designed as a flat seat that has a planar valve seat surface. A circumferential edge located on the face of a sleeve of the control valve rests on the planar valve seat surface when the control valve is closed.
