Abstract (en)
The invention concerns a system for the supply of fuel-injection, internal combustion engines, comprising a pump unit and an injector unit which are part of an integrated assembly. In the pump unit, an intake and supply piston (15) forms a movable anchor, displaced by an electromagnet (13) which exercises its force of attraction against a contrast spring (12). The operation of the electromagnet (13) acts on the piston in the intake direction, while the supply stroke of the piston (15) is driven by the sole elastic energy stored in said spring (12). The instant starting fuel injection coincides with the opening instant of the needle (28) of the injector (27).
