Abstract (en)
[origin: EP0967388A2] Fuel injector for an internal combustion engine, comprising a valve body provided with an inner housing, a therein sliding plunger, in which there are arranged at least a first and a second chamber, three distinct conduits adapted to convey a flow of fuel from a high-pressure source to one of said chambers and a flow of fuel from one of said chambers to the needle valve, in which the outer walls of the plunger are slidably adhering to inner walls of said housing so as to prevent fuel from anyhow leaking or seeping between said two chambers through passages between the plunger and said walls. The outflow section connecting said first conduit with said third conduit within the second chamber is of the same order of magnitude as the outflow section of said needle valve and is further significantly smaller than the outflow section connecting said second conduit within the first chamber. <IMAGE>
