ABSTRACT:
To maintain the pressure with which fuel is injected from a fuel injection valve uniform during the injection period and to provide for atomization of the injected fuel by delivering the fuel through a nozzle adjacent a swirl chamber from a valve in which a continuous fluid flow is maintained from an inlet opening to a drain opening, an auxiliary valve is located adjacent the nozzle and coupled to the nozzle opening member, typically a needle valve cone, to interrupt return or drain fluid flow so that the full pressure of fuel delivered to the swirl chamber is available during injection time and the swirl action maintained, thus atomizing fuel being injected.
