  "textContent": "An injection nozzle (10) for injecting fuel into a combustion chamber of an internal combustion engine is disclosed. The injection nozzle comprises a nozzle body (12) having a valve needle (16) received in a bore (14) and a restrictive element (28) being moveable with the needle (16). In use, fuel passes through a throttle restriction (54) in the bore (14) defined by a clearance (R A , R B ) between the restrictive element (28) and a wall portion (14d) of the bore (14). The clearance (R A , R B ) increases progressively as the valve needle (16) lifts from its closed position. The restrictive element (28) may be a colar press-fitted on the needle shaft and can be adjusted according to measured parameters.",
