Abstract:
A clamping arrangement for a fuel injector, which is insertable into a mounting bole of a cylinder head of an internal combustion engine to directly inject fuel into a combustion chamber of the internal combustion engine, the clamping arrangement comprising:a first step ring at least partially surrounding the fuel injector and resting on the fuel injector via a valve pressure surface, the first step ring including at least one first circumferential slope surface on a side of the first step ring facing away from the valve pressure surface; and a second step ring including at least one second circumferential slope surface and a counterpressure surface; wherein the at least one first circumferential slope surface of the first step ring engages with the at least one second circumferential slope surface of the second step ring, and the at least one first circumferential slope surface of the first step ring and the at least one second circumferential slope surface of the second step ring are arranged so that the first step ring and the second step ring are pressed axially apart when rotated relatively to one another.
