  • Mounting arrangement for a fuel injection pump nozzle in a cylinder head
    Patent number: 5125383
    Abstract: In the embodiment described in the specification, a fuel injection pump nozzle which is received in a recess in a cylinder head is mounted on the cylinder head by a flange which engages a bearing surface on the surface of the cylinder head surrounding the recess. This prevents application of mounting forces to the sealing contact surface in the cylinder head recess, thereby avoiding critical stresses in the region of the cylinder head near the combustion chamber.
