Abstract
Improvements in fuel injectors for internal combustion engines, of the type of liquid fuel injection and compression ignition, characterized by comprising an alternative movement pump for fuel, prepared to supply fuel to an injector thereof, of the type comprising an injection valve arranged to open automatically or, in order to allow current through the orifice or injection holes of the injector, during the injection period, by the fuel pressure accumulated in a pressure chamber of the injector, to which chamber the fuel pump supplies this, and in that the supply means by which the fuel is transmitted from the pump to the pressure chamber, comprises a restricted feed passage, of a relatively small surface cross-section, at least together to the fuel injector or inside it; a main feed passage of relatively large surface effective cross section, arranged in parallel with the reduced passage, and a switching valve disposed in the main feed passage, at a point adjacent to or inside the injector and prepared for closing the communication between the main supply passage and the pressure chamber when the supply pressure of the fuel is relatively low, and to automatically open said communication, when the supply pressure of the fuel exceeds a predetermined value.
