Abstract:
A fuel injector is provided having a needle valve element and a nozzle member with a central bore configured to slidingly receive the needle valve element. The fuel injector also has a spring configured to bias the needle valve element toward a closed position. In addition, the fuel injection assembly has a guide element configured to reduce a lateral movement of the needle valve element. The fuel injection assembly further has a fluid flow restricting device configured to restrict the flow of a fluid through the needle valve element and create a fluid pressure differential between the fluid upstream and downstream of the fluid flow restricting device.
