摘要

The injector comprises an injector head (1) and a supply chamber for fuel staying below high pressure. A discharge chamber (4) is provided for fuel staying below low pressure or no pressure. A control valve arrangement (13) has a valve body (14) at which a quench area is arranged within the discharge chamber. The quench area extends transverse to a closing direction of the valve body. The quench area forms a hydraulic quench slit (24) which is closed during the closing movement.
