Abstract
Official abstract text for this publication.
A dual fuel injector utilizes first and second control valves to open and close first and second nozzle outlet sets to inject a first fuel and a second fuel, respectively. The first and second control valves have concentric lines of action, and include a self alignment feature with respect to a flat seat. The two fuels may differ in at least one of chemical identity, matter phase and pressure.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel injector comprising: an injector body defining a first fuel inlet, a second fuel inlet, a first nozzle outlet set, a second nozzle outlet set, and a drain outlet, and defining therein a first control chamber and a second control chamber; a first check valve member with a closing hydraulic surface exposed to fluid pressure in the first control chamber, and being movable between a closed position in contact with a first seat to fluidly block the firs…
