Abstract:
A fuel injection device for internal combustion engines comprising:a housing means having at least one channel forfuel or pressure medium;a control piston provided within said housing means;at least one pilot valve, whereby said pilot valve displaces said control piston by means of a pressure medium for conveying fuel via said at least one channel in the direction of an injection chamber of said internal combustion engine, whereby said control piston places said fuel or said pressure medium under pressure; anda valve body adjustable between an open and closed position and projecting through said injection chamber, said valve body closing nozzle openings leading to a combustion chamber of said internal combustion engine when said injection chamber is filled with said fuel or said pressure medium, whereby said valve body is pressurized by a pressure causing said valve body to remain in said closed position and, wherein said fuel or said pressure medium is pressurized by a second pressure that is greater than the pressure under which said valve body remains in said closed position, and wherein said valve body is adjustable into the open position under pressure of the fuel or pressure medium, thereby opening said nozzle openings.
