Document Type and Number:
Japanese Patent JP3105244
Kind Code:
B2
Abstract:
An internal combustion engine fuel injector having a selectively openable nozzle (10) through which fuel is delivered to a combustion chamber of the engine. The nozzle (10) comprises a port having an internal annular surface (43) and a valve member (20) having an external annular surface (44) co-axial with respect to the internal annular surface. The annular surfaces are shaped so that when the internal and external annular surfaces are in sealing contact at a seat line adjacent the downstream end of the surfaces, thereby closing the nozzle, the maximum width (47) of the passage between the said surfaces is not substantially more than 30 microns, preferably not more than 20 microns, in the direction normal to said surfaces.
