Patent ID: 6840268

Claim:
A high-pressure connector for a fuel injection system of an internal combustion engine having combustion chambers serviced by fuel injectors, said high-pressure connector comprising: an elongated body having an inlet that is in fluid communication with a source of high-pressure fuel, an outlet in fluid communication with the inlet of a fuel injector and a fuel passage extending between said inlet and said outlet for providing a flow path for high-pressure fuel therebetween, said fuel passage including a main fuel passage and a plenum chamber defined between said main fuel passage and said inlet to said high pressure connector; a filter that is supported within said fuel passage and acts to filter particulates from the high-pressure fuel; and a fuel flow limiter moveably supported in said plenum chamber of said fuel passage among a first position wherein high pressure fuel is collected within said plenum chamber, a second position at which a predetermined quantity of high pressure fuel is delivered from said plenum chamber to said outlet of said high pressure connector at each injection event during normal operation of the combustion chamber serviced by the injector and a third position that terminates fuel flow between said inlet and said outlet of said high pressure connector and to the injector in the event of a malfunction at the combustion chamber.
