Weldable mount for fuel system component

A vent apparatus adapted to be coupled to a fuel tank, the apparatus comprising

• a valve housing made of a non-weldable plastics material, the valve housing including a sleeve formed to include an interior region and a venting outlet arranged to conduct fuel vapor from the interior region of the sleeve through a vent passageway to a destination outside the valve housing, the valve housing further including an upper flange positioned to lie outside of the interior region,
• a valve positioned to lie inside the interior region of the sleeve, the valve being arranged to move within the interior region to open and close a venting aperture interconnecting the interior region of the sleeve and the vent passageway of the venting outlet,
• a ring positioned to extend around the valve housing, the ring being formed to include an annular channel opening toward the valve housing, the upper flange of the valve housing including a radially outer perimeter edge extending into the annular channel formed in the ring,
• a tank mount made of a weldable plastics material, the tank mount including a lower flange lying under the upper flange of the valve housing, the lower flange including a radially outer perimeter edge extending into the annular channel formed in the ring, the tank mount further including a base portion appended to the lower flange and adapted to be welded to an underlying fuel tank to support the valve housing within a mounting aperture formed in the fuel tank, and
• means for establishing a sealed connection between the upper and lower flanges upon extension of the upper and lower flanges into the annular channel formed in the ring.

• a seal positioned to lie under the upper flange,
• a retainer ring positioned to extend around the valve housing and engage the upper flange of the valve housing to limit axial movement of the upper flange away from the seal, and
• a tank mount made of a weldable plastics material, the tank mount including a base potion 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 portion further including a lower flange appended to the base portion and arranged to mate with the upper flange of the valve housing to trap the seal ring therebetween and engage a portion of the retainer ring to limit axial movement of the lower flange away from the upper flange.
