ABSTRACT:
A flapper valve for push-in snap-lock attachment to a spud to be welded to a fuel tank and attached to a flexible filler tube hose. The flapper has an annular flexible seal overmolded thereon, preferably of elastomeric material. The flapper has a pair of trunnions, one of which has an extension or spindle with a resilient member received thereover with one end of the resilient member slidably anchored to a post on the flapper to form a flapper subassembly. The opposite end of the resilient member is deflected to fit in a slot or groove in the body when the trunnions are snapped into a slot formed by at least one deflectable portion formed integrally on the exterior of the tubular valve body for pivoting the flapper. Deflector vanes are provided on the upstream side of the flapper to protect the seal from the end of a siphon hose.
