Abstract
A refueling valve for a motor vehicle includes a body connected to the upper wall of a fuel tank in vertical depending relationship thereon and the body has a body top or cover with a vapor exit passage adapted to be connected to a fuel vapor storage canister, a baffle is connected to the valve body intermediate the ends thereof to form a fuel space and a vapor space; the body includes a portion depending from the cover that has a vapor exit port communicating with the vapor space and wherein the vent exit port has a valve seat closed by a valve mounted on one end of a connecting rod that has its opposite end connected to a float within the fuel space and wherein the vapor exit port remains open until the fuel tank is filled and/or fuel slosh in the tank raises the float to close the valve; the connecting rod is directed through a port in the baffle to provide for vapor exhaust across the baffle during tank fill and to restrict fuel bypass into the vapor space during fuel slosh within the tank. In one embodiment a baffle is a transverse wall and in another embodiment the baffle is an inverted cone having a center vapor relief port therein and a peripheral wall formed with fuel return openings.
