摘要： A fuel injector having an improved sealing of an intake nozzle with respect to the receiving opening of a fuel distribution rail. A support ring, which engages with the sealing ring on the intake side, is provided at the intake nozzle. The support ring includes a planar underside for resting on a shoulder of the intake nozzle and a V-shaped contact surface facing the sealing ring. The support ring, which is acted on by the sealing ring, is provided with the V-shaped conical contact surface for the sealing ring that ensures that in the case of increased pressures, a minor radial escape of the support ring is made possible to the radial inside and outside and thus radial gaps and an extruding of the sealing ring into same are prevented.

摘要： A fuel injector is described which is able to be preassembled in a receiving opening of a fuel-distributor line in a loss-proof manner in a structural unit in the form of a fuel charge assembly for transport to the final assembly at the vehicle manufacturer. A radial support disk for preventing the loss of the fuel injector is disposed on the inflow-side end of the inlet pipe by press-fitting the radial support disk in the receiving opening. The fuel injector is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing internal combustion engine having externally supplied ignition.
