Siphonable poppet-type fill tube check valve

摘要

A tubular poppet type check valve for a fuel tank filler tube having annular barbs on the inlet end for snap-in attachment in a non-metallic tank spud and provisions for push-in connection with the end of a metallic spud which is crimped over a groove. The poppet has an annular groove with an overmolded elastomeric seal formed preferably with a wiper portion for facilitating sealing on a valve seat. The poppet has a post portion slidably guided in an aperture in the closure provided in the downstream of the valve. A slot in the side of the valve body allows a siphon hose inserted in the inlet to exit the valve and feed through to the bottom of the tank. Deflector vanes are provided in the inlet end to direct a siphon hose to the outlet slot. The poppet has turbulence reducing vanes on the upstream side.
