Abstract
A fuel refilling assembly for receiving a filling nozzle to open and close a filler neck of a fuel tank. The refilling assembly has a housing attached to the filler neck to receive the filling nozzle. A pressure valve and a vacuum valve are mounted to the housing. The valves move between seated and unseated positions to automatically equalize the pressure within the filler neck, a filler pipe and the fuel tank. The refilling assembly is characterized by a first flap pivotally mounted to the housing and engaging the vacuum valve for automatically moving the vacuum valve from the seated position to the unseated position. The first flap is pivoted when the filling nozzle is partially inserted within the filler neck. Once the vacuum valve is disengaged, any pressurized fuel vapors within the filler neck, filler pipe and fuel tank are vented to the atmosphere. The venting occurs before the filling nozzle opens the filler neck which ensures a safe filling operation.
