Abstract

A fuel injector for an internal combustion engine includes: an electromagnetic actuating element having a solenoid coil, a core and a valve casing as the outer solenoid circuit component, and a movable valve-closure body, which cooperates with a valve-seat surface assigned to a valve-seat body. The core and a connection pipe are fixedly connected in an inner opening of a thin-walled valve sleeve and the valve casing at the outer circumference of the valve sleeve is fixedly connected to the valve sleeve by being pressed in/on.
