ABSTRACT:
The apparatus for feeding fuel to a motor vehicle engine from a fuel tank includes a pump portion and a direct current drive motor located in a housing part and through which the fuel flows. The commutator device of the drive motor includes commutator brushes located on the positive side and on the negative side; brush contact springs made from electrically conductive material located on the positive side and on the negative side, and a collector having a sliding surface for the brushes which are pressed on it during operation by the contact springs. To improve reliability of operation of the apparatus a negative potential is applied to the brush contact springs on the positive side and on the negative side and the brush contact springs on the positive side are electrically insulated from the commutator brushes on the positive side.
