A fuel inlet 10 includes a fuel inlet body 11 that is formed of resin including a reception pipe portion 20, a filler pipe connection pipe portion 30, a breather pipe connection pipe portion 40, and a fluid introduction portion 60. The reception pipe portion 60 receives a fuel nozzle 3. The filler pipe connection pipe portion 30 is located on a lower side of the reception pipe portion 20 and is connected to a filler pipe 31. The breather pipe connection pipe portion 40 is located on an upper side of the reception pipe portion 20 and is connected to a breather pipe 41. The fluid introduction portion 20 causes foamed fluid to flow along an inner wall surface of the reception pipe portion 20 while liquefying the foamed fluid, the foamed fluid flowing from the breather pipe connection pipe portion 40 to the reception pipe portion 20. The fuel inlet body 11that is formed of resin is formed by integrally molding the reception pipe portion 20, the filler pipe connection pipe portion 30, the breather pipe connection pipe portion 40, and the fluid introduction portion 60.

A fuel supply portion structure of a fuel supply pipe, including a tubular portion having a filler port and a connection port, a first flap mechanism which is provided on the filler port side of the tubular portion, a drain hole, and a drain hole on-off valve, wherein the drain hole on-off valve is disposed on a placement surface located at the lowermost side of a vehicle on an inner wall of a first inner diameter member, the placement surface is made of an inclined surface falling from the filler port side toward the connection port with respect to a horizontal plane of the vehicle, and a wall portion rising toward the filler port is provided on the filler port side of the inclined surface.

A monitoring system for a multiple-walled fluid system with a first walled region including a flowing or stagnant fluid and at least one second walled region at least partially surrounding the first walled region. The first walled region and the at least one second walled region forming the multiple-walled fluid system, the first walled region being in fluid communication with the at least one second walled region, the at least one second walled region also being in fluid communication with the ambient environment. A data processing device for monitoring at least one pressure difference between a pressure in at least one a control volume and at least one second pressure in the at least one second walled region, a first control volume in fluid connection with the first walled region and the ambient environment. The at least one pressure difference indicating the status of the multiple-walled fluid system.

A permanent test port mounting in a conventional gasoline/diesel fuel dispenser to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system to include all or at least more of the line system head pressure than has been possible before. In particular, the test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

A dispenser dispenses a consumable product from a container. The container is supported within a housing by a container holder. The container holder is vertically moveable within a movement range in the housing. A biasing structure biases the container holder upwardly. A sign is connected to move up and down with the container holder. An indicator associated with the sign is vertically fixed relative to the housing. When an amount of product remaining in the container reaches a low level, the biasing force of the biasing structure will lift the container holder, causing the indicator to be aligned with a portion of the sign that gives a visual cue to a user that the amount of product remaining is at a low level.

Methods are devices are provided for preventing fracture of a fluid-filled chamber or tank. In general an anti-fracture expansion device can be disposed internally within a fluid-filled chamber such that during a freeze event displaced fluid can compress or flow into the anti-fracture expansion device, thereby reducing the likelihood that the chamber will rupture. The internal disposition of the expansion device prevents it from interfering with other components that may be connected to or adjacent to the fluid chamber, thereby conserving space. In certain embodiments, the expansion device can have a dual function wherein it can act as a flow control valve in addition to functioning as an anti-fracture expansion device.

A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.

A containment pad with a basin and a porous cover is provided for supporting a vehicle. Service conduits are provided within the containment pad allowing fluid and/or electrical and instrumentation connections to be connected through the containment pad, allowing for example a fuel tank to connect to a dispenser through the containment pad allowing a gas station to use dispensing islands with no underground piping. A modular interlocking design allows multiple lanes and dispensing islands.

In one aspect, the invention relates to a system for monitoring a fluid dispensing system having a storage tank and a piping system having a maximum output flow rate threshold. The system includes a dispenser configured to dispense fluid from the fluid dispensing system during a dispensing time interval, a metering device in fluid communication with piping system, the metering device configured to measure a plurality of sample flow rates over time in response to fluid passing through the metering device, a gauge for measuring a volume of fluid dispensed from the storage tank during the dispensing time interval and a processor for executing a monitoring application which generates an alert within a substantially real-time period in response to an event of interest, the monitoring application comparing the maximum output flow rate threshold to the plurality of sample flow rates over time to generate the alert when one of the sample flow rates exceeds the maximum output flow rate threshold.
