Abstract

An electrostatic charge removing apparatus in a fuel filter is capable of reliably removing electrostatic charge generated in a fuel filter and of reducing cost and weight of the fuel filter by escaping or discharging the electrostatic charge from parts of the fuel filter other than a case of the fuel filter. The fuel filter includes a filter portion that is connected to an outlet of a fuel pump disposed in a fuel tank and is clamped by end plates, a case housing the filter portion therein, wherein the end plates are formed of a conductive material, and a projection that penetrates a cap is formed on one end plate and is grounded.

Independent Claims | See all claims (3)

1. 1. A fuel filter comprises: a container formed of a cap and a case; a filter member, a protector and end plates respectively disposed inside the container, the filter member and the protector being clamped by the end plates; and seal members formed of a conductive material and mounted on both ends of the end plates; wherein the cap and the end plates are formed of a conductive material and the cap is grounded.
2. 2. A fuel filter comprising: a container formed of a cap and a case; a filter member, a protector and end plates respectively disposed inside the container, the filter member and the protector being clamped by the end plates; and seal members formed of a conductive material and mounted on both ends of the end plates; wherein the cap, the end plates and the filter member are respectively formed of a conductive material and the cap is grounded.
3. 3. A fuel filter comprising: a filter portion for filtering fuel and having sufficient conductivity for discharging electrostatic charge; a container formed of an electrically insulating resin, and housing the filter portion therein, said container including an opening; a conductive member mounted on the container to close the opening, and having sufficient conductivity for discharging electrostatic charge; elastic bodies disposed between the conductive member and the filter portion to contact therebetween, and having sufficient conductivity for discharging electrostatic charge, said elastic bodies being elastically deformed; and a grounding member electrically connected to the conductive member to ground the conductive member.
