A valve assembly disposed in a nozzle of a fuel-dispensing pump that, when in an open, operative position, freely allows fuel to flow therethrough. In a closed position, fuel is prevented from dripping from the end of the fuel-dispensing nozzle. A first embodiment provides a spherical or flat, spring-loaded one-way sealing element or check valve that is forced away from the dispensing end of the nozzle to allow fuel to flow therefrom. When fuel dispensing is complete, the check valve seals the nozzle. In a second embodiment, apertures in a cap are rotated between an open and a closed orientation to allow or block fuel passage depending upon their angular position. The valve assembly is press fitted into a conventional fuel-dispensing nozzle.
