Abstract:
An injector body for a fuel injection system, in which the injector body (1) has a longitudinal axis and a substantially cylindrically shaped valve chamber (3), into which fuel can be introduced at high pressure via an inlet bore (2), which discharges into an inlet opening (7) in the valve, chamber (3), the inlet bore having a center axis located at an angle to the longitudinal axis of the injector body, the improvement wherein the valve chamber (3), at least in the region of the inlet opening (7), has a bulge (8) in its cross section in the circumferential direction adjacent to each side of the inlet opening (7), such that the radius of the valve chamber cross section in a plane perpendicular to the longitudinal axis of the injector body and passing through the center axis of the inlet bore at the inlet opening varies in the circumferential direction.
