ABSTRACT:
An improved fuel vapor recovery means surrounding the spout of a fuel-dispensing nozzle is sealed to the fillpipe of, e.g., an automobile fuel tank, by means of a highly anisotropic or mono-directional magnet disposed on the forward portion of the vapor recovery means. Fuel vapor escaping from the fuel tank during the filling operation is thus minimized and the magnet provides sufficient directional force to provide additional support for the entire nozzle. The magnet is preferably of the ceramic type and is magnetically oriented such that it exhibits a strong magnetic force axially of the spout, thereby sealing the vapor collector to the fillpipe, and may be backed by a steel plate to direct and enhance the magnetic forces issuing from the front of the ceramic magnet.
