Abstract

An electromagnetically controlled fuel injector for internal combustion engines wherein the injector needle is normally held on its seat by the pressure of the fuel in a counter-pressure chamber, the release of said pressure which sets the needle in its operative position being ensured by causing the controlling electromagnet to connect the counter pressure chamber no longer with the supply of fuel but with an exhaust channel returning the fuel to the supply to this end, the electromagnet acts on a plunger incorporating a slide valve, ball valve or needle valve controlling channels provided in a nozzle surrounding the rod operating the injector needle which channels lead to the counter-pressure chamber, with the supply and with the exhaust.
