Fuel filter assembly having a conductive spring
摘要:
A fuel filter includes features adapted to collect and drain static electrical charges occasioned by the passage of fuel therethrough. The filter includes a two-piece plastic housing having an end cap and a cylindrical portion with an end defining inlet and outlet fittings. The filter element is cylindrical and includes an outer perforated metal shell, an intermediate pleated paper filter and an inner perforated metal shell. Both metal shells are secured and electrically coupled to an electrically conductive end cap. The electrically conductive end cap is electrically and mechanically connected to a conductive, circular spring. The spring engages a ground pin which extends through the cylindrical portion of the housing and may be connected to a suitable ground to drain off static electrical charges generated by fuel flowing through the filter. The other end of the filter element is either embedded in the housing end cap or, in an alternate embodiment, a smaller end cap which is received in the housing end cap.
