  • Method and apparatus for dry testing vapor recovery systems
    Patent number: 5715875
    Abstract: A vapor recovery valve that includes two mechanisms for opening the valve is disclosed. The first mechanism opens the valve when fuel is being dispensed by a fuel delivery system. The second mechanism selectively opens the valve independent of whether the fuel delivery system is dispensing fuel. A method for dry testing a vapor recovery system is also disclosed. The method involves disabling the fuel dispensing capability of the fuel delivery system, and then operating the vapor recovery system at a rate that corresponds to a predetermined imaginary fuel dispensing rate. Next, the vapor recovery path is opened, and its operation is measured and determined if it is sufficient for the imaginary fuel delivery rate.
