Abstract:
1. A dispensing system for dispensing volatile liquids such as hydrocarbon fuel for vehicles into a tank having a filler neck while collecting the vapors to reduce atmospheric pollution comprising: fuel dispensing means including at least one hand-held nozzle for insertion in the filler neck of a tank and a manually operated valve for providing a variable volume flow rate of fuel into the tank; means for providing an electrical signal indicative of the volumetric flow rate of said fuel delivery means; vapor collection means having a controllable volumetric flow rate, said vapor collection means including vapor intake means attached to the hand-held nozzle and when the nozzle is inserted in the filler neck of the tank being positioned closely adjacent to, but not sealed with, the filler neck for drawing vapor displaced from the tank by delivery-of fuel and for conveying it to a vapor receiving tank; and means responsive to said electrical signal for making the volumetric flow of said vapor collection means greater than the volumetric flow of said fuel dispensing means.
