摘要： A user friendly vapor recovery nozzle with special signaling devices to signal and assure the customer of proper delivery of fuel and return flow of hydrocarbon vapors. In the preferred embodiment, the signaling devices include both a fuel flow indicator and a vapor flow indicator. The flow indicators can comprise one or more fuel and vapor driven balls, paddle wheels, propellers, spinners, blades, or vanes. In the preferred form, the vapor recovery nozzle has an inner fuel spout to discharge gasoline into a customer's tank and has an outer spout which cooperates with the inner spout to provide a vapor return passageway to return vapors emitted during fueling to a vapor return hose. The nozzle has a liquid sensing tube in the vapor return passageway to sense when the customer's tank is filled. An automatic shutoff valve cooperates with the liquid sensing tube to shutoff the supply of gasoline when the customer's tank is filled. The nozzle also has a venturi sleeve which can be connected to a condensate liquid pickup tube to remove condensed vapor in the vapor return hose. A flow control valve assembly is provided to regulate the flow of gasoline. Fuel flow indicators can be operably positioned in the flow control valve assembly. The flow control valve assembly can have transparent cap to view the fuel flow indicators. The nozzle can further has a vapor check valve to regulate the flow of vapors. Vapor flow indicators can be operably positioned and viewed in the vapor check valve.

摘要： A process comprising fueling a tank, collecting emitted vapors, and recovering condensed vapors. In the process, gasoline is discharged into a fill opening or filler pipe of a tank through a fuel outlet conduit of a nozzle. Gasoline vapors emitted during fueling are collected with a vapor return conduit of the nozzle and conveyed through a vapor return hose. A portion of the gasoline vapors in the vapor hose are condensed and removed from the vapor hose with a condensate pickup tube extending from the nozzle.

摘要： A Stage II Vapor Recovery System is provided with a special array of storage tanks, dispensers, fuel pumps, vapor assist pumps, and flow control nozzles, to capture hydrocarbon emissions, prevent condensate from blocking vapor return lines, and dispense gasoline or other liquid fuel and condensate to customer tanks. Specifically, fuel lines connect storage tank to flow control nozzles via dispensers and are assisted by fuel pumps to pump gasoline into customers' tanks. The nozzles have vapor passageways to capture hydrocarbon vapors emitted during fueling. The captured vapors are pumped by vapor assist pumps from the vapor passageways through vapor return lines into the storage tanks. The nozzles are equipped with condensate liquid pickup tubes to remove condensed vapors blocking the vapor return lines. The condensate liquid tubes communicate with condensate venturi ports adjacent venturi sleeves in the nozzles. Liquid sensing tubes in the vapor return passageways activate automatic shutoff valves in the nozzles to shut off the flow of gasoline when the customer's tank is filled.

摘要： In the process, fuel is pumped from a storage tank through a dispenser and nozzle into a customer's tank. Hydrocarbon vapors emitted during fueling are collected through a vapor recovery passageway between the inner and outer spouts of the nozzle and conveyed by a vapor pump through vapor return lines into the storage tank. A portion of the vapors in the vapor return lines condense and are removed with the nozzle's condensate pickup tube. The removed condensate is dispensed into the customer's tank.

摘要： The anti-theft device for use in a liquid storage tank having an opening in an upper wall of the tank for receiving and mounting an access fill pipe which receives therein a drop tube having an access port. The anti-theft device comprises a mounting ring; a plug; a truncated porous hollow cone having a larger upper end fixed to the mounting ring and a smaller lower end fixed to the plug which is disposed generally concentric with the elongate axis of the drop tube. The plug may also be provided with a shaped key-way opening to allow gauging of liquid contents of a storage tank with a gauge level stick. The mounting ring of the truncated porous hollow cone is attached to the drop tube within the access fill pipe at a point below the access port of the drop tube and above the upper wall of the storage tank. The key-way opening of the plug can be T-shaped, cross-shape, C-shape, or of a circular-shape.
