Fuel injector.

摘要

A direct injection fuel injector has a fuel conduit 14, a fuel inlet 11 and a fuel outlet 13. An electromagnetically-controlled plate valve 20 regulates a flow of fuel along conduit 14 and a further valve including a needle valve member 36 allows fuel to exit the conduit via the outlet provided the differential pressure across the further valve exceeds a predetermined amount. The further valve member is effective to close the outlet in response to the pressure developed during compression in the combustion chamber. <IMAGE>
