Abstract
A fuel injector (1), in particular for direct injection of fuel into the combustion chamber of an internal combustion engine, is equipped with a valve-closure member (4) which together with a valve-seat surface (6) that is formed on a valve-seat body (5) constitutes a sealing seat, with an ejection orifice (7) and with a swirl module (34). The swirl module (34) incorporates a plurality of tubular hollow bodies (43) which are disposed parallel to one another in a cluster (44) and which impart turbulence to the fuel flowing towards the ejection orifice (7) through the fuel ducts (45) formed in the hollow bodies (43).
