Patent ID: 7802584

Claim:
A fuel injector for an internal-combustion engine comprising a hollow body; a metering valve housed within the hollow body and having a calibrated pipe for outlet of fuel from a control chamber; a shutter, controlled by an electromagnet, for keeping the calibrated pipe normally closed, the electromagnet comprising a magnetic core having an annular slot; an electric coil carried by a bobbin, housed in the annular slot, and comprising a substantially cylindrical outer surface, said bobbin having a C-shaped section defined by a substantially cylindrical rib interposed between two flanges substantially planar and parallel to one another; a pair of a appendages mounted on one of said bobbin flanges each appendage supporting a first end of one of a pair of plugs for connection to an electrical supply; said appendages inserted into two corresponding holes in said magnetic core and defining corresponding gaps between the holes and the appendages; and a block of non-magnetic material englobing said magnetic core and at least a portion of said plugs, said block comprising a pair of bushings that fit within said corresponding gaps to englobe at least a portion of said appendages projecting from said holes; wherein said block and said annular slot define a space that permits fuel exiting the control chamber to contact the outer surface of said electrical coil.
