ABSTRACT:
An auxiliary vapor recovery device is described for use with a fuel dispenser for delivery of fuel from tanks into a vehicle and a recovery apparatus for return of hydrocarbon vapor/air mixture displaced by fuel delivery to ullage spaces of the storage tanks interconnect by a piping manifold. The auxiliary vapor recovery device includes a vacuum pump and a canister containing a substance for removal of molecules of hydrocarbon from a vapor/air mixture. The device also has a system of conduits, including between the vacuum pump and ullage space piping system for flow to and from the ullage space, to the canister, between the vacuum pump and canister, and from the canister for release of air. The device also includes a solenoid valve system with first and second solenoid valves positioned in the conduit system, the solenoid valve system having a first (recovery) condition for permitting flow of hydrocarbon vapor/air mixture from the ullage space, through the canister for removal of hydrocarbon vapor and release of air, a second (off) condition for restricting flow of vapor in the conduit system and a third (stripping) condition for establishing an increased vacuum condition within the canister for return of hydrocarbon vapor to the ullage space. A solenoid valve system control apparatus causes the solenoid valve system to move among the first, second and third conditions.
