WELDABLE MOUNT FOR FUEL SYSTEM COMPONENT

摘要

A vent apparatus is adapted to be coupled to a fuel tank and includes a valve housing made of a non-weldable plastics material and containing a valv e. The vent apparatus further includes a tank mount made of a weldable plastics material and coupled to the valve housing. The tank mount is adapted to be welded to an underlying fuel tank to support the valve housing within a mounting aperture formed in the fuel tank. The tank mount is coupled to the valve housing by a retain er ring formed to include an annular channel opening toward the valve housing. The valve housing includes an annular upper flange extending into an upper region of t he annular channel formed in the retainer ring. The tank mount includes an annular lower flange extending into a lower region of that annular channel to mate with the overlying annular upper flange and trap a flange seal therebetween.
