Abstract:

A fuel injector apparatus and method is provided for use in a fuel injection system of an internal combustion engine that includes a body, a valve seat, closure member, and an orifice plate. The valve seat comprises the intersection of two angled surfaces with a radius before assembly of the fuel injector. During assembly of the fuel injector, a member presses against the radius edge of the sealing surface of the valve seat to create an oblique third sealing surface or sealing band that is coined into the valve seat. The sealing band provides an improved seal between the valve closure member and the valve seat which operates to prevent leakages of fuel in the fuel injector.
