International Classification:

B67D 538

US Classification:

141 94

Abstract:

A user friendly vapor recovery nozzle with special signaling devices to signal and assure the customer of proper delivery of fuel and return flow of hydrocarbon vapors. In the preferred embodiment, the signaling devices include both a fuel flow indicator and a vapor flow indicator. The flow indicators can comprise one or more fuel and vapor driven balls, paddle wheels, propellers, spinners, blades, or vanes. In the preferred form, the vapor recovery nozzle has an inner fuel spout to discharge gasoline into a customer's tank and has an outer spout which cooperates with the inner spout to provide a vapor return passageway to return vapors emitted during fueling to a vapor return hose. The nozzle has a liquid sensing tube in the vapor return passageway to sense when the customer's tank is filled. An automatic shutoff valve cooperates with the liquid sensing tube to shutoff the supply of gasoline when the customer's tank is filled.
