Gasoline vapor recovery system

摘要

A gasoline vapor recovery system which includes a gasoline pump, a gasoline dispenser, a gasoline line with a flow sensor in it, and a gasoline vapor line with a pressure responsive valve in it which is operated by differential pressurefrom the flow sensor. The flow sensor is located in the gas dispenser and the pressure responsive valve is located below the gas dispenser to eliminate one of the impact valves which were heretofore required to provide a safer construction.
