Abstract
An improved disk-valve fuel injector comprising a self-centering, floating valve seat insert disposed in a valve body. The valve seat insert includes a circular first valve seat and the body includes a circular second valve seat concentric with the first valve seat. A spring urges the valve insert into compliance with a disk-shaped valve head. The valve insert is able to adjust position in all three dimensions, allowing the disk head to mate precisely with both seats, thereby minimizing leakage when the valve is closed, improving metering precision, and extending the working lifetime of the valve head and valve seats.
