Clamping device for fuel injection nozzles

Claim 1

In combination, an injection nozzle, a cylinder head of an internal combustion engine, a clamping device in the form of a bracket for use in clamping the fuel injection nozzle to the cylinder head, and fastening means for fastening opposite, longitudinally extending top end sections of the clamping device to the cylinder head, said clamping device comprising: (a) a generally flat top portion having substantially parallel top and bottom surfaces, defining a centrally disposed slot formed therein for receiving therethrough a portion of the injection nozzle, and including said opposite longitudinally extending end sections adapted for use with the fastening means; and (b) two parallel leg portions extending from opposite sides of said top portion each having substantially parallel side surfaces perpendicular to the top and bottom surfaces of said top portion, said leg portions and said top portion defining, throughout their longitudinal extent, a U-shaped cross-sectional profile with the free end of each of said legs defining a bearing surface which faces the cylinder head, said legs being adapted, when said device is assembled with the injection nozzle and means fastening said clamping device to the cylinder head, to bear against a respective flattened portion on the injection nozzle.
