<p>Figure 3 shows a fuel flow control valve assembly having a high pressure fuel inlet 106 intermittently pressurized, and a low pressure supply pump inlet connected to a fuel pressurization chamber and to a prechamber fuel injector 26, the high pressure fuel moving a plunger 136 to unseat a ball valve 142 and pressurize the fuel to the injector 26 to inject fuel through it, the stroke of the plunger being determined by the spacer 140, seating of the ball valve 142 against a seat 138 terminating flow to the injector 26, continued pressurization in inlet 106 then opening the pressure relief mechanism of the main chamber injector 18.</p> |
