ABSTRACT:
A liquid dispensing and vapor recovery system and a vapor control unit used therein in which the control unit has a pair of inlets for receiving liquid, such as gasoline, from an underground storage tank and for receiving gasoline vapors from a vehicle tank during dispensing of the gasoline into the latter tank. A first passage is provided in the control unit for passing the gasoline from the storage tank to a hose connected to the vehicle tank, and an additional passage is provided in the control unit for diverting a portion of the gasoline. A valve is provided which controls the flow of gasoline through the additional passage in response to the flow of gasoline through the first passage and an injector nozzle is provided in the additional passage for drawing vapors from the vehicle tank and into the second passage for mixing with the gasoline before being discharged back to the storage tank.
