ELECTROMAGNETIC NOZZLE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; fuel injection equipment of internal combustion engines. SUBSTANCE: electromagnetic nozzle has external housing, coil placed on core made in form of cylinder with internal stepped bore. Hollow armature rigidly connected with shutoff member engaging with seat is placed inside bore which accommodates also a stop. Flexible member pressing shutoff member to seat is placed in armature space. Second end of flexible member is pressed on by stop. Guide bead is made on end face of stop getting into armature space. Width of guide bead on stop is selected so that angular displacement of armature axis relative to nozzle is sufficient for tight fit of shutoff member to seat. EFFECT: enlarged operating capabilities. 1 dwg
