Abstract

A fuel filtering device is provided for insertion within a fuel inlet aperture of a motor vehicle fuel tank. The device includes a thin metal tube having a filtering mesh covering the inserted end of the tube. A fume reducing barrier is supported across the interior of the tube by a resilient thin metal strip attached to the device at or near the opposite open end of the tube. An opening is formed in the body of the tube to enable the barrier to swing outwardly beyond the exterior of the tube against the resilient force of this strip when a fuel filling nozzle is inserted within the tube beyond the barrier. The device also has means for preventing the withdrawal of the device through the fuel inlet aperture of the motor vehicle when a previously inserted nozzle is withdrawn from within the device.

Dependent claims

A fuel filtering device for insertion within a fuel inlet aperture of a fuel tank comprising,

a thin elongated metal tube having one end open for receiving a fuel filling nozzle and having filtering means covering its other end, said tube having a further opening in the body thereof,
a fume reducing barrier member,
a thin, flexible and resilient metal strip extending parallel to the axis of said tube having one end attached to said barrier member, and having its other end attached to said device at a location between said open end and said body opening of said tube,
said barrier member being normally supported by said strip in a position through said body opening and transverse to the interior of said tube and being dimensioned to substantially close the internal passageway provided by said tube, and
said body opening being large enough to permit the outward movement of said barrier member through the body of said tube against the resilient force of said strip when a fuel filling nozzle is inserted within said tube beyond said barrier member.
