Abstract
A fuel injector, particularly an injector of an internal combustion engine, has a piezoelectric or magnetostrictive actuator which is arranged in an actuator chamber which is sealed against the fuel, the fuel injector having a valve-closure member which can be actuated by the actuator via a valve needle, and which cooperates with a valve-seat face to form a sealing seat. In this context, the seal for forming the permeation-resistant sealing contains at least two elastomer sealing devices arranged in tandem.
