Abstract
A fuel injector is described, in particular an injector for fuel injection systems in internal combustion engines, that includes a valve needle having a valve-closure member which cooperates with a valve-seat surface arranged in valve-seat member to form a sealing seat and which has several injection orifices which are arranged downstream from the sealing seat, and are sealed by sealing seat against a fuel supply. A disk element is arranged downstream from the sealing seat, the disk element having at least one valve section, which changes its shape when the temperature changes. Valve section is connected to a heating element and optionally covers an injection orifice.
