ABSTRACT:
A fuel injection valve comprising a main fuel injection valve body having an inlet opening for fuel and a port for discharge of fuel, a fixed core in the valve body, an electromagnetic coil in the valve body, a movable core attracted magnetically towards the fixed core by the coil and a valve member coupled to the movable core for opening and closing the fuel discharge port. A socket portion is on the valve body to define an end portion for supply of fuel to the inlet opening and the socket portion includes an end flange formed by plastic deformation of the socket portion to dispose the flange radially on the socket portion and provide a radial swarf-free surface on the flange capable of sealed engagement with a connection member having a fuel passage connectible with the fuel inlet. The plastic deformation is achieved by rotating a tool on the edge of the initially straight socket portion to bend an edge portion of the socket portion to form the end flange.
