The present invention provides an electric pump, the electric pump comprising: a motor unit which includes a shaft, a rotor coupled to the shaft, and a stator disposed outside the rotor; a pump unit which includes a first rotor including a first lobe coupled to the motor unit and having a plurality of gear teeth, and a second rotor disposed outside the first rotor and including a second lobe; and a second cover including a second surface on which the pump unit is disposed, wherein the second surface has a second suction port and a second discharge port disposed thereon, and the second suction port provided on the second surface includes a third protrusion protruding to the inside of the second suction port. The angle formed by a first line connecting the center of the first rotor and the center of the second rotor, and a second line connecting the center of the first rotor and a distal end of the third protrusion is inversely proportional to the number of gear teeth of the first lobe.

    La présente invention concerne une pompe électrique, la pompe électrique comprenant : un ensemble moteur qui comprend un arbre, un rotor accouplé à l'arbre, et un stator disposé à l'extérieur du rotor ; un ensemble pompe qui comprend un premier rotor comprenant un premier lobe accouplé à l'ensemble moteur et possédant une pluralité de dentures, et un second rotor disposé à l'extérieur du premier rotor et comprenant un second lobe ; et un second couvercle comprenant une seconde surface sur laquelle l'ensemble pompe est disposé, un second orifice d'aspiration et un second orifice d'évacuation étant ménagés sur la seconde surface, et le second orifice d'aspiration ménagé sur la seconde surface comprenant une troisième partie saillante faisant saillie vers l'intérieur du second orifice d'aspiration. L'angle formé par une première ligne reliant le centre du premier rotor et le centre du second rotor et une seconde ligne reliant le centre du premier rotor et une extrémité distale de la troisième partie saillante, est inversement proportionnel au nombre de dentures du premier lobe.
