Abstract
A fuel injector for injecting fuel into the combustion chamber of an internal combustion engine includes an injector body in which an annular chamber into which an inlet bore discharges at an orifice point is embodied. A pressure tube neck with a sealing face is embodied on the injector body. The pressure tube neck is offset from the line of symmetry of the annular chamber; the inlet bore, embodied in the pressure tube neck, ends at a tangent, at an obtuse entrance angle, in the annular chamber at the orifice point.
Claims6
A fuel injector for injecting fuel into the combustion chamber of an internal combustion engine comprising
- an injector body (1) in which an annular chamber (5) is embodied, and into which an inlet bore (10) discharges at an orifice point (12), and
- a pressure tube neck (7) with a sealing face (9) embodied on the injector body (1),
- the pressure tube neck (7) being disposed offset from the line of symmetry of the annular chamber (5), and
