Abstract

This invention relates to an electric fuel pump (10) of membrane type for automobile vehicle, durable in use, simple in conception and presenting a high yield for a small volume. Particularly, it is provided for motor vehicles of two wheels without limiting its utilization. The pump according to this invention comprises at least a membrane (50) directly connected to a piston (22), the axial alternating motion of which creates a depression or a suppression within a working chamber (60). The piston is driven by the rotation of a motor through the mechanism of gear means. The latter comprises a cylindrical eccentric cam (42) driven by the rotation of an axle (30) of an electric motor through gear means (32,34,36,38;32,74,76,80), the axes of gear means and that of cam being parallel to the axle (30) of motor and perpendicular to the displacement direction of the piston (22).
