ELECTROMAGNETIC NOZZLE (VERSIONS) Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed electromagnetic fuel nozzle container outer case, coil shutoff element, seat, stop axially extended into armature space, core, hollow armature rigidly coupled with shutoff element engaging with seat, elastic element arranged in armature space for pressing shutoff element to seat. Stop made of non-magnetic material is secured in adjusting screw located in core. Stop is provided with shoulder to thrust against end face of adjusting screw. Element made of hard non-magnetic material is found on end face of stop. Elastic element is located in armature space around stop between bottom of armature housing and adjusting washers thrusting against stop shoulder. According to other design version, adjusting screw and stop are made in form of one part manufactured from non-magnetic material on end face of which hard non-magnetic element is located. Elastic element is arranged in armature space around stop between bottom of armature housing and adjusting washers thrusting against stop shoulder. EFFECT: simplified design, increased service life of nozzle. 8 cl, 4 dwg
