Abstract
A fuel injector for gaseous fuel is provided. The fuel injector includes a valve assembly with a fuel flow valve and a second valve. The fuel flow valve is actively controlled to permit and prohibit gaseous fuel flow through the fuel injector. The second valve is spaced from the fuel flow valve and passively controlled to open in response to the gaseous fuel flow though the fuel flow valve, and to close when the gaseous fuel flow is terminated by closing the fuel flow valve.
