摘要

#CMT# #/CMT# The fuel injection valve device has a valve needle (10), which controls an injection opening (12) by its longitudinal movement of the opening and with a control chamber (20), whose pressure indirectly affects the valve needle. A discharge channel mouth is averted from the control chamber, which is arranged outside the guide pin in the control valve body. #CMT#USE : #/CMT# Fuel injection valve device for an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The fuel injection valve device has a discharge channel mouth is averted from the control chamber, which is arranged outside the guide pin in the control valve body, and thus enables an economical manufacturing of the fuel injection valve device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a fuel injection valve. 1 : Retaining body 2 : Nozzle body 10 : Valve needle 12 : Injection opening 20 : Control chamber.
