FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed electric fuel pump of fuel injection system of automobile engine has housing, electric motor, pumping unit in form of labyrinth screw pump installed directly in space of electric motor. Grooves of rotating part of pump are made on peripheral cylindrical surface of electric motor armature in from of multistart thread, and grooves on nonrotating part of pump are made on inner cylindrical surface of stator in form of multistart thread with hand of helix opposite to thread on armature.
EFFECT: reduced material usage and overall dimensions of pump, reduced labor in manufacture of electric fuel pump.
