DEVICE TO INJECT FUEL IN ICE COMBUSTION CHAMBER Russian patent published in 2013 - IPC F02M47/02 F02M63/02 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises atomizer with needle displacing axially to control opening or closing by control chamber pressure. Control chamber pressure is controlled by at least one solenoid valve that opens or closed fuel inlet and outlet channels. Valve coil interacts with armature whereto valve shutoff element is engaged and pressed against valve seat. Said armature is arrange in its chamber wherein discharge channel terminates. Magnet coil on armature chamber side is coved by metallic protective annular plate. The latter is arranged inside annular chamber of pot armature and retained therein by lugs clamping said protective plate. Said lugs are made of pot magnetic core material by, preferably, indentation by stamping tool with extending teeth.

EFFECT: ruled out cavitation erosion in fuel atomiser.
