Abstract
A fuel injector, in particular an injector for fuel injection systems in internal combustion engines, has a piezoelectric or magnetostrictive actuator. The actuator operates a valve closing body by means of a valve needle, working together with a valve seat face to from a sealing seat. A fuel line leads from a fuel inlet connection to the sealing seat. A fuel line leads from a fuel inlet connection to the sealing seat. The actuator is tubular and surrounds at least some sections of the fuel line.
