Securing means for fuel injection nozzles

Means for securing a fuel injection nozzle body to the cylinder head of an internal combustion engine, the body having a generally circular cross section, a flattened area provided on the outer surface of the nozzle body along a portion thereof and a shoulder forming part of the nozzle body and bounding the flattened area, with the shoulder extending radially inwardly towards the flattened area, said securing means comprising

• A. a separate flange having:
• 1. a first opening of a diameter at least as large as the diameter of the nozzle body for permitting the latter to pass through said flange;
• 2. a second opening extending from said first opening and having a width sufficiently large to receive the thickness of the nozzle body at the flattened area thereof;
• 3. a third opening extending from said first opening for receiving therethrough bolt means;
• 4. a fourth opening separate from said other openings for receiving therethrough bolt means;
• and
• B. bolt means dimensioned for reception within said third and fourth opening for tightening said flange to the cylinder head, whereby said flange engages the shoulder of the nozzle body with a flange portion immediately adjacent and along said second opening and thereby clamps the nozzle body to the cylinder head.
