  • Patent number: 3996979
    Abstract: A vapor recovery nozzle for use in filling vessels with a liquid and for recovering liquid vapors generated by the liquid such as the filling of vehicle fuel tanks. The nozzle includes a valve system including a first valve for the liquid and a second valve for the vapor and an interconnection whereby the vapor valve is always open whenever the liquid valve is open. It also includes a common actuator for the two valves and an automatic shutoff system for the liquid valve, which automatic shutoff system includes a connection to the vapor line when the nozzle is being used in vacuum assisted vapor recovery systems and further forms part of a drain system for a vapor collection hood surrounding the spout of the nozzle so as to drain liquid received therein from the vapor flow path to preclude such vapor from contaminating components of a vapor recovery system.
