    摘要: A fuel vapor vent valve for a motor vehicle is connected to an upper wall of a fuel tank in vertically depending relationship. The valve has a cover with a vapor exit passage connected to a fuel vapor storage canister and a body depending from the cover. One embodiment has a vapor exit port that communicates with the fuel tank interior adjacent the upper wall of the fuel tank. A vent tube has one end connected to the vapor exit passage and an opposite end that communicates with the vent exit port and defines a valve seat. The vapor exit port is located with respect to the valve seat so as to separate liquid fuel particles from vapor flow during fuel fill. The valve seat is closed by a valve element attached to a float when the fuel tank is full. Several further embodiments of the valve have the body connected to the cover to accommodate side impacts to the fuel tank.
