2. Fast fuel system - Wikipedia

   en.wikipedia.org/wiki/Fast_fuel_system

   These refueling Fast Fill Systems utilize an automatic shut off fuel nozzle, receiver and level control device. Refueling Fast Fill Systems operate by connection of a fill nozzle to the vehicle's fuel tank and with a source mounted pump that delivers fuel into the tank at rates up to 150 US gallons (570 L) per minute.

3. Vapor recovery - Wikipedia

   en.wikipedia.org/wiki/Vapor_recovery

   Gas nozzle with vapor recovery. Vapor (or vapour) recovery is the process of collecting the vapors of gasoline and other fuels, so that they do not escape into the atmosphere. This is often done (and sometimes required by law) at filling stations, to reduce noxious and potentially explosive fumes and pollution.

4. Shut-off nozzle - Wikipedia

   en.wikipedia.org/wiki/Shut-off_nozzle

   Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.

5. Gasoline pump - Wikipedia

   [26] This mechanism eventually developed into the modern gasoline pump cut-off valve. [27] Most modern pumps have an automatic cut-off feature that stops the flow when the tank is full. This is done with an auxiliary sensing tube running from just inside the mouth of the nozzle to a Venturi pump in the pump handle. A mechanical valve in the ...

   Pressure in blanketed tanks is maintained by self actuating pressure control valves (PCVs). As liquid is withdrawn from the tank the pressure in the gas space falls. The blanket gas supply valve opens to maintain the pressure. As the tank fills with liquid the pressure rises and a vent gas valve open to vent gas to atmosphere or a vent system. [11]

   The most common ones are shut-off or filter-lock valves, which are used to stop flow in the service line. These may be operated by vacuum or electricity. On bi-fuel systems with a petrol carburettor, a similar shut-off valve is usually fitted in the petrol line between the pump and carburettor.
