摘要

Injector (1) for injecting fuel into combustion chambers of internal combustion engines comprises a control part (2) protruding into a control space (8). The pressure is released via an actuator (3) and the control part is loaded by spring elements (17, 23) in the injector housing. The control part is guided in a guide sleeve (11) surrounding the control space. Preferred Features: The guide sleeve loaded by a spring element (17) lies on the housing wall (10) of the injector. The guide sleeve is centered on the first diameter region (15) of the control part.
