ELECTROMAGNETIC INJECTOR FOR INTERNAL-COMBUSTION ENGINE

摘要

engine manufacture; electronic-control fuel-injection devices fore gasoline engines. SUBSTANCE: injector has body accommodating atomizer and electromagnetic coil; mounted inside the latter are armature press-fitted onto shut-off needle tip and core attached to body both separated by clearance; axial hole of core accommodates spring and hollow adjusting screw that presses the latter to armature; flexible interference-fit joint between core and adjusting screw ensures self-locking of the latter; adjusting screw has cylindrical collars on its ends and longitudinal through slots on its threaded portion which ensures its reliable automatic locking in position without impairing functional characteristics of injector. EFFECT: improved efficiency of injector functional characteristics. 2 dwg
