    摘要: A venting system for venting a gaseous fluid from a tank having an aperture and a fuel delivery module cover. The tank is made of a predetermined material. The venting system comprises a venting valve disposed within the aperture. The venting valve includes a valve body having a top portion and a neck portion extending from the top portion. The top portion is disposed outside the tank and is engaged thereto. The venting system further includes a channel which connects to the valve body so that the venting valve is in fluid communication therewith and is attached to the fuel delivery module cover to allow the gaseous fluid in the tank to be vented therefrom. The venting system further includes a cover which is comprised of the same predetermined material and is welded to the tank to seal the valve between the cover and the tank.

    摘要: A device that is adapted to be mounted to an interior surface of a polymeric fuel tank includes a body, a weld foot adapted to be inserted into the molten inner surface of the fuel tank and having a support surface adapted to control insertion of the weld foot into the molten inner surface of the fuel tank and to position the device relative to the inner surface, and a break zone positioned between and interconnecting the weld foot and the body and having a structural cross section that is weaker than the weld foot and the body such that under sufficient force, the break zone will fracture and allow the body to separate from the inner surface of the fuel tank, thereby leaving the weld foot embedded within the inner surface of the fuel tank.

    摘要: The present invention involves a low permeation pinchoff connection at a pinchoff region having a pinchoff end between first and second formed sheets of a fluid tank. The low permeation pinchoff connection comprises a continuous inner polymeric layer at a pinchoff region having a pinchoff end between the first and second formed sheets. The connection further comprises an outer polymeric layer in side-by-side relationship with the continuous inner polymeric layer. The outer polymeric layer tapers at the pinchoff region to first and second outer polymeric ends at the pinchoff end separating the first and second outer polymeric ends. The connection further comprises a low permeation barrier layer disposed between the continuous inner polymeric layer and the outer polymeric layer. The low permeation barrier layer tapers with the outer polymeric layer at the pinchoff region to first and second barrier ends separated at the pinchoff end to determine a pinchoff gap. The low permeation barrier layer is exposed at the pinchoff end. The connection further includes a first adhesive layer disposed between the continuous inner polymeric layer and the low permeation barrier layer, and a second adhesive layer disposed between the low permeation barrier layer and the outer polymeric layer. The connection further comprises a barrier bridge disposed on the pinchoff end to bridge the pinchoff gap. The barrier bridge has material compatible with low permeation barrier layer to connect the first and second barrier ends for continuity therebetween.
