Abstract

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