Static dissipater for a fuel filter assembly

摘要

Static dissipaters for eliminating static electricity in fuel filter assemblies and fuel filter assemblies including static dissipaters are provided. The static dissipaters are in the form of a static dissipation sleeve that is disposed around the outside of a fuel pump within a fuel filter assembly. The static dissipation sleeve has one or more protrusion portions that protrude radially from the surface of the static dissipation sleeve and provide contacts for static dissipation of static electricity.

主权项

1. A fuel filter assembly comprising:
a housing; a fuel pump; a filter element assembly disposed outside of the fuel pump and including a filter medium for filtering fuel; a static dissipation sleeve disposed outside of the fuel pump and in contact with an outer surface of the fuel pump; and a water separation tube disposed between the static dissipation sleeve and the filter medium; wherein the static dissipation sleeve includes a plurality of protrusion portions defining annular rings around a periphery of the static dissipation sleeve that project radially outward and contact the water separation tube; and wherein the annular rings are located at a central portion of the static dissipation sleeve and at both axial ends of the static dissipation sleeve.
