ABSTRACT:
A fuel injection valve comprising a main fuel injection valve body containing an electromagnetic coil which is operative to displace a movable core having a valve rod attached to the core. The valve rod has an end with a valve body adapted to selectively engage a valve seat-forming member attached to the valve body. The valve seat-forming member has an interior including a guide bore for guiding opening and closing displacement movements of the valve rod. The guide bore has a uniform diameter throughout its entire length and is connected to a valve seat formed at the end of the guide bore in continuation thereof. A fuel discharge port is formed in continuation of the valve seat. The guide bore is straight and has a burnished surface and the valve seat also has a burnished surface for contact by the valve body. The guide bore is connected to the valve seat without any undercut and due to the burnishing, the guide bore and valve seat are connected without flashing.
