Title:
流体噴射器の直接作動式速度制御ノズルバルブ
Document Type and Number:
Japanese Patent JP4108783
Kind Code:
B2
Abstract:
The present invention provides direct control over the opening and closing of a fuel injector nozzle valve independent of fuel injection pressure or engine operating condition and allows for initial fuel injection rate shaping by controlling the opening velocity of the nozzle valve. The present invention further allows for control over the closing velocity of the nozzle valve thereby reducing stresses on the nozzle tip as the check engages the check seat while not adversely affecting the performance of the fuel injector. This results in lower tip wear and improved life of the fuel injector.\!
