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.

In a vapor recovery nozzle for use in filling tanks with vapor forming liquid products or the like, the combination, comprising: a spout adapted to be introduced into the inlet of a tank to be filled; a vapor collection hood disposed about said spout and adapted to engage substantially the entire periphery of a tank inlet when said spout is introduced therein; a manually operable liquid flow control valve in fluid communication with said spout and adapted to control the flow of liquid from a source to said spout; means in fluid communication with said hood for establishing a vapor flow path therefrom to a vapor recovery device and including a vapor flow control valve in said flow path; and means associated with said valves for causing said vapor flow control valve to open prior to and close after opening and closing respectively of said liquid flow control valve in response to manual operation there, whereby a vapor flow path to a vapor recovery device will always be established whenever liquid is flowing to said spout; both said valves being on a common actuator; and said means associated with said valves for causing said vapor flow control valve to open prior to and close after opening and closing respectively and said liquid flow control valve including a lost motion connection between said common actuator and said liquid flow control valve.
