Abstract
A fuel injector pressurizes fuel in a pressurization chamber and ejects the fuel from an orifice. A reverse flow check valve allows fluid communication between the pressurization chamber and the orifice during fuel injection, but blocks fluid communication between the pressurization chamber and the orifice when fuel pressure in the pressurization chamber decreases.
