ABSTRACT:
A vapor-recovery system in which a coaxial vapor-recovery fuel dispensing nozzle cooperates with portions of the vehicle fuel receiving and storage system to prevent the escape of vapors into the atmosphere during refueling. The fuel-dispensing nozzle comprises a rigid, tubular vapor-recovery member coaxially arranged around the nozzle discharge spout to define a vapor-recovery passageway therebetween. A seal means is located inwardly of the fuel tank fillpipe opening to sealingly engage the vapor-recovery member when the nozzle discharge spout is operatively inserted into the fillpipe so that substantially all refueling emissions will flow into the vapor-recovery passageway of the vapor-recovery member. The coaxial vapor-recovery nozzle also includes a vapor seal valve operable by the fuel pressure available in the nozzle to seal the outer end of the vapor-recovery member when the nozzle is not in use, and to open the outer end of the vapor-recovery member when the nozzle discharge spout is operatively inserted into the fillpipe and the fillpipe seal means sealingly engages the vapor-recovery member. The nozzle further includes a no-seal, no-flow interlock for preventing the nozzle from dispensing fuel until the fillpipe seal means sealingly engages the vapor-recovery member, the no-seal, no-flow interlock opening and closing with the opening and closing of the vapor seal valve.
