Title:
FUEL INJECTION VALVE FOR INTERNAL COMBUSTION ENGINES
Document Type and Number:
WIPO Patent Application WO1999057432
Kind Code:
A3
Abstract:
The invention relates to a fuel injection valve comprising a nozzle body (300) which has a central guide boring (312) and an approximately circular supply channel (338) which has a radius (r1) and which is located to the side of said guide boring (312). Both the guide boring and supply channel open into a pressure chamber (334), whereby the supply channel (338) is shaped by an electroerosive machining device (700). In another embodiment, the nozzle body (300) comprises a shoulder situated on the front end thereof. Due to the constructive characteristics, the nozzle body (300) exhibits a greater resistance to pressure.
