Magnetic valve controlled injection device

Claim 1

A magnetic valve controlled fuel injection device comprising: a fuel pump in a pump casing; and a fuel nozzle for internal combustion engines; a mounting means hole for the fuel pump casing in a cylinder head of the engine; a guide fuel pump piston means in the casing displaceable longitudinally thereof by a camshaft means via a drive element, supported from the cylinder head side; said pump piston means shutting off a control hole emerging in a pump working space; a second mounting hole means provided in the cylinder head for the fuel nozzle; pressure conduit means starting from the pump working space and leading to the fuel nozzle and to a magnetic valve means controlling the beginning of pumping and the end of pumping as a function of operating parameters of the internal combustion engine; the magnetic valve means forming a structural unit jointly with at least one of the fuel pump and the fuel nozzle; the first mounting hole means for the pump being provided in the cylinder head; the pump being located separately from the fuel nozzle and connected to the fuel nozzle by a relatively short exposed pressure pipe means; the first mounting hole means for the pump allowing for unencumbered removal of the pump from the camshaft means; the fuel nozzle being independently fastened to the cylinder head by said second hole mounting means to be removable towards the outside of the engine; and a portion of the casing, facing away from the drive element and the magnetic valve means being both located outside the space enclosed by the cylinder head and a cylinder head cover.
