Abstract: A vapor recovery nozzle, employed in minimizing atmospheric pollution by fuel vapors is described. The nozzle comprises a bellows which is compressed against the fill pipe of a vehicle fuel tank during discharge of fuel therein. The bellows surrounds a nozzle spout to define a vapor return flow path which extends through a nozzle body.

Abstract: A fuel vapor entrapment device, during fueling of a motor vehicle fuel tank, traps escaping fuel vapors so as to enhance vacuum-assisted vapor recovery system operation. By deflecting fuel vapors and capturing them temporarily until their removed to a vapor storage tank, the device substantially prevents the escape of fuel vapor into the atmosphere and enables the vapor recovery system to capture a higher percentage of escaping fuel vapor. During the fueling process, the fuel entrapment device encircles the vehicle tank filler port, thereby forming a vapor containment area from which fuel vapors are removed, and prevents the ingestion of excessive ambient air into the vapor recovery system. A vacuum relief hole permits the ingestion of a limited amount of ambient air so as to prevent the build up of excessive negative pressure and avert vehicle fuel tank collapse during vacuum-assisted vapor recovery operation.
