INJECTOR FOR CAR

摘要

PURPOSE: An injector for a vehicle is provided to minimize an impact noise generated by the operation between a plunger and a solenoid part because diaphragms are installed inside a housing. CONSTITUTION: An injector for a vehicle comprises a housing(100) installed in a fuel supply pipe(P) of an engine, a solenoid part(200) which is installed in the housing and generates a magnetomotive force, a plunger(300) moving up and down according to the operation of the solenoid part, and a needle valve(400) which is installed in the lower part of the housing and has an injection nozzle(420). A first diaphragm(510) and a second diaphragm(520) are installed in the housing in order to absorb an impact noise generated by the operation of the solenoid part. Hydraulic oil is filled between the first diaphragm and the second diaphragm.
