Abstract
Official abstract text for this publication.
A fuel pump includes: an electric motor; a pump stage drivable by the electric motor; and a fuel pump housing configured to accommodate the electric motor and the pump stage. The fuel pump housing has a first housing part configured to accommodate the electric motor and a second housing part configured to accommodate the pump stage. One or both of the first housing part and the second housing part are made of a conductive plastic adapted to dissipate static charges to a ground potential.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel pump, comprising: an electric motor ( 4 ); a pump stage ( 6 ) drivable by the electric motor ( 4 ); and a fuel pump housing ( 8 , 9 , 10 ) configured to accommodate the electric motor ( 4 ) and the pump stage ( 6 ), wherein the fuel pump housing ( 8 , 9 , 10 ) comprises: a first housing part ( 10 ) configured to accommodate the electric motor ( 4 ), the first housing part ( 10 ) being made of a conductive plastic adapted to dissipate static charges to a ground potential; and a second housing part ( 8 , 9 ) configured to accommodate the pump stage ( 6 ) and being made of the conductive plastic. 2. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises graphite powder. 3. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises carbon fibers. 4. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises metal fibers. 5. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises graphite powder and carbon fibers. 6. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises graphite powder and metal fibers. 7. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises carbon fibers and metal fibers. 8. The fuel pump as claimed in claim 1 , wherein the conductive plastic comprises graphite powder, carbon fibers and metal fibers. 9. A fuel delivery unit comprising the fuel pump ( 2 ) as claimed in claim 1 .
