ABSTRACT:
A pressure-vacuum relief fuel filler cap comprising a cover, having a base and a peripheral flange, and a sub-assembly mounted at least partially within the cover with said peripheral flange surrounding a portion of the sub-assembly. The assembly comprises a body of synthetic plastic material including an outer threaded end adapted to engage a threaded filler opening, and an enlarged upper end with portions thereof engaging the base of the cover. A pressure relief valve and associated valve seat are mounted within the body and a vacuum relief valve and associated valve seat are mounted within the body. Torque limiting means are provided between the body and the cover for limiting the torque applied to the body during application to a filler opening, so that when a predetermined torque is reached, the cover can be rotated relative to the body and when the cap is rotated in the opposite direction, there can be no relative movement between the cover and the body.
