Title:
ELECTROMAGNETIC OPERATING VALVE
Document Type and Number:
Japanese Patent JPS6141086
Kind Code:
A
Abstract:
An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines having fuel injection systems. The fuel injection valve includes a valve housing, a core having a magnetic coil and an armature, which is guided by a guide diaphragm and is firmly connected to a bearing tube. Protruding into the bearing tube is a spherical pivot segment of a valve member, which is on the one hand partially surrounded and engaged by a pan-shaped segment of the bearing tube and on the other hand is axially fixed by means of a retainer ring. Joined to the pivot segment is an elongation segment, on the other end of which a spherical sealing segment is secured, and which is further radially guided by means of a guide ring and thereby cooperates with a valve seat in a nozzle body. Since the pivot segment is pivotably supported in the bearing tube, shear forces at the armature have no effect on the sealing segment.
