Abstract (en)

[origin: EP1486665A1] In a fuel injector (1) whose injector body (2) is equipped with a magnetic valve (4) for fuel injection control that has a magnet unit (6) composed of multiple components assembled into a fixed sleeve (61), escape passages (67B) is formed inside the fixed sleeve (61) for allowing air trapped in gaps of the components in the fixed sleeve (61) by pressurized fuel sent to the magnet unit (6) to escape outside the fixed sleeve (61) and be replaced by fuel. The trapped air present in the gaps between the components in the magnet unit (6) of the magnetic valve (4) is rapidly replaced with fuel at the start of operation so that stable control of the quantity of injected fuel can be reliably established in a short time. <IMAGE>
