Abstract
A liquid dispensing and vapor recovery system in which a control unit is connected to a storage tank for the liquid and directs the liquid to a pair of conduits which pass the liquid to a receptacle and back to the storage tank, respectively. A reduced pressure zone is established in the conduit connected to the storage tank and is in communication with the receptacle for drawing vapors from the receptacle for passage back to the storage tank. The control unit prevents the flow of liquid back to the storage tank until gasoline is delivered to the receptacle and modulates the vapor flow back to the storage tank in response to the flow through the conduit connected to the receptacle.
