ABSTRACT:
The escape of fuel vapors from gasline storge tanks during refueling results in significant air pollution and loss of high octane components of the fuel mixture. Presently available systems all take the approach of drawing these vapors from the auto during refueling, through expensive underground plumbing at each service station and then condensing or absorbing these vapors in one large condensing or absorbing unit. This invention, using replaceable cannisters (containing sufficiently cold contact surfaces for condensing the gasoline vapors at the hand dispenser), uses a pressure drop created by the flowing liquid gasoline to return the vapors condensed in the replaceable cannisters back to the consumers' autos or other vehicles. Thus, considerable savings in construction costs of underground service station plumbing is realized in addition to giving the consumer the (high octane) vapors for which he has already paid. The pressure drop (or "jet pump", as commonly referred to in the industry) also can open various spring loaded valves which can prevent air convection losses when not refueling, thus increasing the time intervals before the (spent) condenser cannisters must be replaced with cannisters (from service station freezers) with frozen heat absorbing brine or other type of ice.
