摘要

Device for withdrawing an injection nozzle of a fuel injection system pressed into a cylinder head of an internal combustion engine comprises a support ring having ring sections provided with interlocking elements interlocking with a support cylinder (2) to prevent radial slippage of each ring section and simultaneous sliding of each ring section. Preferred Features: The interlocking elements consist of guiding pins which axially protrude into the support cylinder. The support ring has a larger inner diameter than the outer diameter of the assembly cylinder of the injection nozzle.
