More Information
Summary: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.
