EM fuel injection valve for external ignition Diesel engine - has hollow magnetic armature with recess supporting flange of coupling tube

摘要

The magnetic armature (12) has at least one recess (5), on the shoulder (16) of which a flange (7) of a connection tube (36) of the valve body (10) rests. At an axial distance from the flanging (7) a double-over section (11) lies also at the magnetic armature. The latter (12) is provided with -a second recess (15), at the shoulder (19) of which the thickness lies. Both recesses (5,15) are identical. The magnetic armature is designed symmetrically. The connection tube (36) has a slot extending over the entire connection tube. ADVANTAGE - Produced in simple and cost effective manner. Smallest possible inherent wt. Non-cutting machining. Very small response times. No welding or soldering of magnetic armature with connection part.
