Abstract:
The high-pressure gas tank includes a seal member extended in a layer-like form to cover the opening recess from a surface of the liner on an outer side of the inner circumferential wall of the mouthpiece placing portion to a surface of the mouthpiece flange on a center side of the flange outer peripheral edge. In a vertical section of the high-pressure gas tank, the flange outer peripheral edge and the inner circumferential wall of the mouthpiece placing portion are formed to satisfy Dt>(Sm/Xgs)·100, where Dt denotes a width of an opening of the opening recess, said Dt being defined to be a distance between a flange outer peripheral edge-side end and an inner circumferential wall-side end of an opening of the opening recess. Sm denotes a maximum tolerance of a relative positional misalignment between the inner circumferential wall of the mouthpiece placing portion and an outer circumferential end of the flange outer peripheral edge, and Xgs [%] denotes a breaking elongation of the seal member.
Abstract:
Systems and methods for installing a compressed natural gas housing apparatus to a vehicle are disclosed. The housing apparatus is configured to be retrofitted to existing cab liners used on refuse vehicles. The complete installation of the housing apparatus and roof liner are disposed below the roofline of the refuse vehicle. The housing apparatus can be configured to contain a variable number of compressed natural gas tanks. The housing apparatus is installed such that the length of the gas pipeline and electrical wiring connected to the apparatus from the vehicle engine and controller is minimized. The location of housing apparatus provides the additional safety of minimizing the exposure of the gas tanks to falling debris or prevent possible contact with the compressed natural gas tanks being damaged as vehicle travels under bridges, other low objects, or contact in the event of a rollover accident.
Abstract:
This invention relates to a pressure vessel that is wrapped with a high-tension winding that prevents or ameliorates the effects of fatigue due to cyclic pressurizing and de-pressurizing of the vessel.
Abstract:
A gas pressure regulator is provided that includes a body defining a front portion and opposed side portions. A first gas pressure indicator is mounted to a lower end of the front portion of the body, and a second gas pressure indicator mounted to an upper end of the front portion of the body, wherein the first gas pressure indicator and the second gas pressure indicator are stacked in a vertical configuration. Additionally, a pressure adjustment knob is mounted to one of the side portions of the body in one form of the present disclosure.
Abstract:
High pressure gas vessels can have a sensitivity to temperature of the compressed gas. Over-temperature conditions in particular may cause decreased durability and/or vessel damage, including gas leakage to the environment. Articles of manufacture, methods, and systems are provided for over-temperature protection using a passive device. The passive closing device does not require electrical power and no controller, sensors, or wiring is needed. This affords cost savings in comparison to other systems. Pressure vessels using the passive closing device can protect themselves, independent of the compressed gas fueling station configuration.
Abstract:
Herein a floating vessel is disclosed. The floating vessel comprises a body structure, a tank for at least temporarily storing a liquid, and at least one pipe connected to the tank. The floating vessel further comprises a tunnel having a first end portion and a second end portion extending through the body structure. The tunnel is arranged in open connection to an ambient environment of the floating vessel. There is least one pipe connected to the tank extending at least partially through the tunnel.
Abstract:
The invention relates to a pressurised fluid container, in particular a pressurised gas cylinder, comprising a body (1) forming a sealed storage volume for the fluid. According to the invention, a first end of the body (1) comprises an opening (2), while a second end of the body (1) comprises a base (3) secured to the body (1). The body (1) is formed by a metal material, a metal alloy or aluminium. The container is characterised in that the base (3) comprises a metal material, a metal alloy or an aluminium alloy having an electronegativity on the Pauling scale that is greater than that of the material forming the body (1). The invention also relates to a method for the production of such a container.
Abstract:
A gas cylinder safety purge and anchor system features a gas cylinder with a plurality of cylinder apertures located around a neck outside periphery. The system features a cylindrical purge deflector with a plurality of deflector apertures located on a internal deflector cap component wall that align with the cylinder apertures when the purge deflector is positioned on the neck. The system features a valve on the cylinder. The system features an anchor assembly having a linear outer tube and a linear inner shaft located in the outer tube. In a first position, a first anchor projection, a second anchor projection, a third anchor projection, and a fourth anchor projection are each located perpendicularly with respect to the outer tube. In a second position, the first anchor projection, the second anchor projection, the third anchor projection, and the fourth anchor projection are each retracted.
Abstract:
A station for supplying a flammable fluid fuel, the station (1) comprising a first cryogenic tank (2) for storing flammable fuel in the form of a cryogenic liquid, a second cryogenic tank (3) for storing a non-flammable gas and notably an inert gas stored in the form of a cryogenic liquid, a cooling circuit (4, 14) in a heat-exchange relationship with the first tank (2), the cooling circuit (4, 14) comprising an upstream end connected to the second cryogenic tank (3) for drawing cryogenic fluid from the second cryogenic tank (3) in order to give up frigories from the fluid of the second cryogenic tank (3) to the first tank (2), the station comprising a circuit (4, 14, 7) for withdrawing fluid from the second tank (3), characterized in that the station comprises at least a detector (5) of fuel leaks from the first tank (2) and at least a controlled member (6, 11) for opening a portion of the withdrawing circuit (4, 14, 7), the at least one opening member (6) being controlled automatically in response to a detection of a leak by the at least one detector (5) in order to release fluid derived from the second cryogenic tank (3) so as to inert a volume within the station.
Abstract:
