Abstract:
Methods and systems for modular fuel storage and transportation are provided. In an embodiment, a fuel storage system includes one or more fuel containers each supported by a fuel container support assembly. The fuel storage system may be mounted to a transportation device such as a vehicle or used in a stand-alone fashion. Each support assembly may include a plurality of detachable end support members such as end support members configured to support the end portions of the fuel container and side support members configured to support the body portion of the fuel container. Some of the end support members may include neck grooves such that when the end support members are coupled, the neck grooves form an enclosure around the neck portion of the fuel container. In an embodiment, the support assembly is configured to facilitate release of excess pressure in the fuel container.
Abstract:
A fuel cartridge, which is capable of being mounted on a tool main body of a gas-combustion type driving tool so as to supply fuel gas to a striking mechanism of the tool main body, is provided with an ejection nozzle provided at a port portion formed at an end portion of a cartridge main body and slidable with respect to the cartridge main body; a compression spring for biasing the ejection nozzle so that a tip end of the ejection nozzle protrudes from the cartridge main body; and an ejection hole formed at a side wall of a tip end portion of the ejection nozzle.
Abstract:
A vertically-oriented cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, an outer vessel surrounding the inner vessel, and a liquid level gauge for indicating a liquid level within the inner vessel. The liquid level gage includes a level indicator located outside of the outer vessel, a support arm extending down into the inner vessel, a swing arm pivotably secured to the support arm and connected to the level indicator so that angular position of the swing arm provides an indication of liquid level within the inner vessel on the level indicator, and a float on the swing arm that pivots the swing arm as the liquid level rises and lowers. The support arm forms an acute angle with the central longitudinal axis of the inner vessel so that the swing arm can be longer to move over a larger portion of the length of the inner vessel.
Abstract:
There is provided a protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which a proximal end of the valve is connectable in use. The protection structure comprises first and second structural sections, the first section being connectable to the valve such that the second section is spaced from the valve by the first section. Further, in use, the second section is arranged to transfer impact forces to the first section, and the second section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve.
Abstract:
The invention relates to a tank comprising a container with an opening and a cover, a flexible casing lying against the interior and exterior of the container. This allows increased resistance to the penetration of sharp objects, liquid and gaseous gases can be used interchangeably and various gas types with a fossil-type and biological-type consistency can be mixed and also heated and cooled in the tank. The invention relates to tanks (1) and staged tanks of the preceding claims, characterised in that in addition to LNG, said tanks can store biological methane gas.
Abstract:
A liquefied gas system and method can supply gas from a liquefied gas container more efficiently by using an external stabilizing device. The liquefied gas is located under its own vapor pressure in the lower portion of the container. As the vapor is withdrawn from the container at ambient pressure, the liquid evaporates at an equivalent rate to account for the decrease in pressure. The stabilizing device surrounding the liquefied gas container efficiently transfers the ambient external heat to the liquid thus allowing more liquefied gas to be vaporized.
Abstract:
A valve device of the present invention includes: a main valve body interposed between a first pressure chamber of a main passage and a second pressure chamber; and a pilot valve body provided in the second pressure chamber. A first pilot passage including a first restrictor extends from an outside of a housing or a primary passage to the second pressure chamber, and a second pilot passage including a second restrictor is formed at the main valve body. The pilot valve body is maintained at a first operation position by a pilot valve body biasing member and is caused to move to a second operation position by a valve body driving unit. When the pilot valve body is located at the second operation position, the main valve body is caused to move to an open position by a pressure difference between the first pressure chamber and the second pressure chamber.
Abstract:
A pressure vessel is disclosed, the pressure vessel having an outer shell, an inner shell, and a temperature regulating device, the temperature regulating device adapted to regulate the temperature of a fluid stored in the inner shell during operation of the pressure vessel and to minimize curing time during manufacture of the pressure vessel.
Abstract:
Embodiments of the present invention relate to compressed gas storage units, which in certain applications may be employed in conjunction with energy storage systems. Some embodiments may comprise one or more blow-molded polymer shells, formed for example from polyethylene terephthalate (PET) or ultra-high molecular weight polyethylene (UHMWPE). Embodiments of compressed gas storage units may be composite in nature, for example comprising carbon fiber filament(s) wound with a resin over a liner. A compressed gas storage unit may further include a heat exchanger element comprising a heat pipe or apparatus configured to introduce liquid directly into the storage unit for heat exchange with the compressed gas present therein.
Abstract:
A structure of a horizontal type cylindrical double-shell tank mounted on a ship includes: an inner shell storing liquefied gas; and an outer shell forming a vacuum space between the inner shell and the outer shell. A pair of support units supporting the inner shell is disposed between the inner shell and the outer shell. Each support unit includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the inner shell side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at the outer shell side. Each of the cylindrical elements is made of glass fiber reinforced plastic.
