Abstract

L'invention concerne une pompe à carburant électrique (10) du type à membrane pour véhicule automobile, résistante à l'usure, de conception simple, présentant un rendement élevé pour un encombrement faible. Elle est notamment destinée aux moteurs des véhicules deux roues, sans toutefois se limiter à cette utilisation.The invention relates to an electric fuel pump (10) membrane type for a motor vehicle, resistant to wear, of simple design, with high efficiency for a small footprint. It is particularly intended for engines of two-wheeled vehicles, but not limited to this use.

La pompe selon l'invention comprend au moins une membrane (50) directement reliée(s) à un piston (22) dont le mouvement axial alternatif crée une dépression ou une surpression dans une chambre de travail (60). Le piston est entraíné à partir de la rotation du moteur par un mécanisme d'entraínement. Ce dernier comprend une came (42) à excentrique cylindrique entraínée en rotation à partir de l'arbre (30) du moteur électrique par l'intermédiaire d'un engrenage (32, 34, 36, 38 ; 32, 74, 76, 80), les axes de l'engrenage et de la came étant parallèles à l'arbre (30) moteur et perpendiculaires à la direction de déplacement du piston (22).

Figure 00000001
The pump according to the invention comprises at least one membrane (50) directly connected (s) to a piston (22) whose reciprocating axial movement creates a depression or an overpressure in a working chamber (60). The piston is driven from the rotation of the engine by a drive mechanism. The latter comprises a cam (42) with cylindrical eccentric rotated from the shaft (30) of the electric motor via a gear (32, 34, 36, 38, 32, 74, 76, 80 ), the axes of the gear and the cam being parallel to the motor shaft (30) and perpendicular to the direction of movement of the piston (22).
