Abstract

An injector for internal combustion engines that includes a fuel injection chamber (20) with a valve seat (24) and at least one injection hole (22), an injector needle (26) with a closing surface (28) movable between open and closed positions, a pressurization chamber (40) connected to a fuel inlet port (42) and to the injection chamber (20), a control chamber (44) connected to a confinement fluid inlet port (46), and a differential pressure regulator (50) that separates the two chambers by means of annular sealing surfaces (541, 561) which in an end-of-stroke position of the separator piston (52) cooperate to establish a sealing contact, or ensures that the pressurization chamber (40) is pressurized as a function of the pressure in the control chamber (44), maintaining a positive pressure difference between the two chambers.
