Systems and methods for a heated gas cylinder assembly are disclosed. The heated gas cylinder assembly may comprise a cylinder shell and a heat exchanger disposed within the cylinder shell. The heat exchanger and the cylinder shell may define an interior chamber configured to hold a gas mixture. The heat exchanger may comprise an inner bore configured to receive a pyrotechnic composition. In response to igniting the pyrotechnic composition, the heat exchanger may provide thermal conduction to the gas mixture. The gas mixture may be simultaneously heated and released, or the gas mixture may be preheated before release.

An assembly for stored containment of fuel including a high-strength, impact resistant container having a hermetically sealed, fuel containing chamber and a nozzle operatively connected in fluid communication with the chamber. The nozzle includes a conduit disposed in fluid communication with the chamber and a sleeve movable relative to the conduit, between an inward retracted position and an outwardly extended position. The conduit at least partially defines a liquid flow path out of the chamber and a gaseous flow path into the chamber is disposed between the conduit and the sleeve. A seal assembly is mounted on the sleeve and movable therewith relative to the conduit to define a first opening of the liquid flow path and a subsequent opening of the gaseous flow path, both into fluid communication with and between the chamber and an exterior of the nozzle.

An object is to propose a fluid handling device for liquid hydrogen that prevents evaporation of liquid hydrogen, and moreover affords excellent heat insulation without liquefying oxygen in the vicinity. In a fluid handling device for liquid hydrogen, piping sections (1) have a heat insulation structure, a swivel joint section (2) is configured with helium gas sealed into a boundary relative-rotation section (6) between an outer ring section (3) and an inner ring section (4) with a bearing section (5) interposed, and moreover, between an outside-air-contacting wall section (7) that is in contact with the outside air and a liquid-hydrogen-contacting wall section (8) that is in contact with liquid hydrogen, a vacuum section (9) extends in the axial direction and moreover a heat-conducting extended path section (10) is provided with one end connected to the outside-air-contacting wall section (7) and the other end connected to the liquid-hydrogen-contacting wall section (8), extending the heat conduction distance between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8), and reducing heat conductivity between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8).

An attachment for communication of fluid from a fluid source. The attachment may include at least one fluid passage permitting fluid flow through the body of the attachment, and at least one valve engaging portion in the body. The valve engaging portion may be configured to open a valve of the fluid source when the attachment is attached to the fluid source or when the attachment is moved towards the fluid source.

Provided is a tube fitment used in a fitment valve assembly having a vertical cylindrical housing and a horizontal cylindrical channel connected to each other in a T-shape, the vertical housing having a top section, a middle section, and a lower section, the top section of the housing having a front wall and a partially open back wall, where the opening is the locus for connecting a spout valve assembly; the horizontal cylindrical channel having a first opening at the first end proximate to the joint of the T-shaped tube fitment and at the top of the horizontal cylindrical channel; having an activator pin and an O-ring situated in the second section of the vertical cylindrical housing that is narrower that said first section of said vertical cylindrical housing.

A boot assembly that reliably seals the secondary containment area utilizing a split boot device that can be installed without disconnecting the primary piping is disclosed. The seal includes first and second containment housings, each supporting a pair of partial ring shaped seals. The containment housings can be positioned about the primary and secondary pipes from opposing sides thereof so that disconnection of the primary pipe is not required to secure the seal in place. A clamp secures the first containment housing relative to the second containment housing in a secured position in which a first pair of partial ring seals associated with the first containment housing and a second pair of partial ring shaped seals associated with the second containment housing cooperate to form a pair of continuous ring shaped sealing surfaces including a first continuous ring shaped sealing surface including one of the first pair of partial ring shaped seals and one of the second pair of partial ring shaped seals, and a second continuous ring shaped sealing surface including a second one of the first pair of partial ring shaped seals and a second one of the second pair of partial ring shaped seals.

Disclosed is a valve apparatus of a urea tank for a vehicle, the valve apparatus configured such that a urea solution injection pipe is flexibly bent and has a float so that a urea injection valve provided at the urea solution injection pipe is prevented from being immersed in the urea solution in the urea tank. Thus, the urea solution can be prevented from being damaged upon freezing in a winter season. Further, when a urea solution is injected, the urea solution injection pipe is straightened by flow pressure of the urea solution such that the float is forced to be immersed in the urea solution in the urea tank, and accordingly the urea solution injection valve is immersed therein. Thus, the urea solution can be efficiently injected into the urea tank.

Fuel dispensers, systems and methods are provided for electronically transmitting data characterizing fueling transactions in a fueling environment, and in particular from a fuel dispenser. In an exemplary embodiment, a fuel dispenser is provided having a printer module that can perform operations that enable any one or more of replacing a printer, providing a user with a printed transaction record at a remote location, and/or provide the user with an electronic transaction record. The application of the printer module can facilitate providing a user with a printed and/or electronic transaction record, while minimizing, or eliminating, changes to standard communication protocol associated with components of a payment terminal that can deliver formatted transaction data to a typical printer. Minimizing or eliminating changes to standard communication protocol associated with providing users with transaction records can facilitate retrofitting the printer module to existing fuel dispensers, and/or simplify design considerations for new dispenser.

A system for storing fuel includes a support structure supporting at least one fuel tank a predetermined distance above ground. The fuel tank includes an inner tank configured to contain a gaseous fuel, an intermediate tank encompassing the inner tank and defining a first annular space therebetween, and an outer tank encompassing the intermediate tank an defining a second annular space therebetween. The first annular space is filled with a shock-absorbing resin for absorbing structural stresses, while the second annular space is filled with an insulating material providing for fire and ballistic resistance. The intermediate tank is connected to the support structure and to at least one adjacent fuel tank, and prevents the transfer of load to the inner tank.
