Abstract: Protective devices are provided subjacent to the filler port within an aircraft's wing fuel tank so as to protect the lower wing skin from being struck by a nozzle associated with refueling equipment. When inserted into the filler port, the nozzle is brought into contact with the protective device which serves to deflect the nozzle in laterally (e.g., in an inboard direction) to thereby prevent the nozzle from striking the lower wing skin. Thus, when initially inserted into the filler port in a generally perpendicular orientation relative to a horizontal plane, the terminal end of the nozzle will contact with the arcuately concave inner surface of the device such that continued insertion of the nozzle into the filler port will cause the nozzle to assume an angularly canted condition in an inboard direction (i.e., a direction toward the aircraft's fuselage).

Abstract: A fuel vapor recovery system of a vehicle has a fill pipe inlet assembly located at a distal end of a fuel tank fill pipe. The inlet assembly has a cylindrical wall defining an elongated cavity divided axially into upstream and downstream regions by a restrictor plate which carries a hole for close receipt of a fuel supply nozzle of a remote fuel pump.

The fuel vapor enters the upstream region at an aperture carried by the wall disposed immediately upstream from the restrictor plate and downstream from a hood. The hood limits vapor release to atmosphere and draws the vapor downstream through a port carried by the restrictor plate for entrainment of vapor into the liquid fuel in the downstream region.
