Abstract (en)
[origin: WO0233249A1] A fuel injection valve (1), in particular for the direct injection of fuel into the combustion chamber of an internal combustion engine with charge compression and external ignition, comprises a spinning disc (35) with helical channels (36), a central recess (38) and a guide compensator (41), arranged in the recess (38), the mid-axis of which may be inclined relative tot the mid-axis of the fuel injection valve (8) and which has a sealing fit against the valve needle (3). A sealing seat is formed from a sealing seat surface (39), arranged in the spinning disc (35) and a radial extension (40) of the guide compensator (41), which is tolerant of a displacement relative to the mid-axis and which prevents the occurrence of a non-spinning leakage, just as the sealing fit between valve needle (3) and guide compensator (41).
