Outwardly opening nozzle valve for a fuel injector

摘要

A fuel injector comprises an injector body which defines a nozzle chamber that is separated from a plurality of outlet orifices by a conical valve seat. An outwardly opening valve member, which is at least partially positioned in the injector body, includes a closing hydraulic surface exposed to fluid pressure outside the injector body. The valve member is movable between a closed position, in which the conical valve seat is closed, and an open position.
