ABSTRACT:
A liquid dispensing and vapor recovery system in which an underground storage tank is connected to a first conduit for delivering a liquid, such as gasoline, to a vehicle gasoline tank or the like under the force of a pump located in the storage tank. A second conduit is connected to the first conduit and to the storage tank for diverting a portion of the gasoline in the first conduit back to the storage tank and an injector is located in the second conduit for forming a reduced pressure zone. A third conduit is connected to the vehicle tank and to the second conduit at the reduced pressure zone for drawing the vapors from the vehicle tank into the second conduit for passage into the storage tank. Valve means are provided which are responsive to the rate of flow of the liquid through the first conduit for regulating the flow of vapor through the third conduit.
