Abstract (en)
[origin: EP0688950A1] The injection valve has a valve needle (31) to control an injection aperture (36). The needle is loaded in opening direction by fuel from the pump working chamber, and by a spring (45) in closing direction. The spring is located in a fuel-filled chamber (43), which is not under high pressure. One end of the valve needle defines a damper chamber (39), the axial wall of which forms a stop (40) to limit the valve needle movement. The damper chamber is connected via a throttle aperture to the fuel chamber. The throttle is formed by a connection (42) and an opening in a spring-loaded pressure journal (48). <IMAGE>
