Abstract

Improvements in the construction of rotary hydraulic pumps driven by permanent magnet dc motor, particularly for the fuel supply in motor vehicles, characterized in that said pumps comprise an external envelope constituted by two elastic and hermetically coupled insulating parts, housing a part, or body, to the engine and having a housing for the rotation shaft of the latter, the housings for the collector brushes, which is of radial type, and the fuel outlet connector, housing the other part, or cover, to the rotary mechanism for entering and sucking the fuel and presenting the other housing of the motor shaft and the fuel inlet connector, said pump also having a magnetic frame fixed, by axial forcing, to ribs or longitudinal protrusions presented by the body, way that between the frame and the body is formed in channels that connect the entrance with the exit of the fuel, and because said frame has magnets of such shape and dimensions that define about the armature longitudinal channels of considerable dimensions, so that the fuel reaches the exit passing through two series of parallel tracks, practiced between the frame and the body and between that and the armature.
