Fuel injector for injecting fuel into combustion chamber of internal combustion engine, has magnetic valve accommodated in valve area in injector body of injector, where valve area is separated into wet area and dry area over diaphragm

摘要

The fuel injector (10) has a magnetic valve (12) for operating an anchor plate (30) and an anchor bolt (32), and accommodated in a valve area (34) in an injector body (14) of the injector. The valve area is separated into a wet area (36) and a dry area (38) over a diaphragm (40). The diaphragm is made of a metallic solid material and as an elastomer-metallic compound. The diaphragm is connected directly with an inner side of a solenoid sleeve or with a hinge at a join pitch. The diaphragm has a magnetic area in an outer circumference.
