A vehicle may include: a fuel tank; a first fuel inlet connected to the fuel tank and configured to connect to a fuel supply nozzle; and a second fuel inlet connected to the fuel tank and configured to connect to the fuel supply nozzle. An inner diameter of the second fuel inlet may be smaller than an inner diameter of the first fuel inlet.

The invention relates to a device for storing compressed gas, for example hydrogen or natural gas, comprising a storage line (1) to which at least one compressed gas container (2) is connected via a valve (3). According to the invention, the storage line (1) has at least one connection port (4) for the gas-tight connection of the at least one compressed gas container (2), and a safety element (5), which has a filter function and a shutoff function, is integrated in the connection port (4). The invention further relates to a vehicle having a device according to the invention for storing compressed gas.

There is provided a fill-up restriction valve including: a housing; and a float valve. The housing includes a housing body including a body-side peripheral wall, and a lower cap including a cap-side peripheral wall, the lower cap being installed to a lower side of the housing body by a joint portion. The joint portion includes an annular groove, an insertion wall portion, and an annular protrusion formed on one of the insertion wall portion and the annular groove, or an annular seal member disposed between the insertion wall portion and the annular groove. The annular protrusion or the annular seal member is configured to be in pressure-contact with the annular groove and the insertion wall portion in a state where the insertion wall portion is inserted into the annular groove.

A gas fuel storage device for a vehicle is provided. The device more easily secures a gas fuel storage capacity and prevents interior marketability of the vehicle from deteriorating.

A refuse vehicle includes a chassis having a prime mover, a body assembly coupled to the chassis, a tailgate pivotally coupled to the body assembly, an energy storage device coupled to the tailgate and moveable therewith, at least one of a non-structural conduit, a non-structural raceway, and a non-structural channel configured to contain at least one of wiring and a hydraulic line, and an impact mitigation system including at least one frame member positioned to direct impact loads around the energy storage device. The prime mover is configured to be powered by the energy storage device. The impact mitigation system provides a protected region within which the energy storage device is disposed.

This disclosure describes an assembly for gas (e.g., compressed natural gas) storage. The assembly includes multiple gas storage tanks, with each tank coupled to a separate sub-assembly that includes a pressure gauge, shutoff valve, and pressure relief device (PRD), providing for independent pressure monitoring, shutoff, and pressure relief for each of the tanks.

Some embodiments include a system. The system can comprise an energy source supply hub and an energy source supply appliance. The energy source supply hub can comprise a hub energy source supply system and a hub vehicle configured to transport the hub energy source supply system. Further, the hub energy source supply system can comprise a hub energy source supply subsystem configured to receive an energy source. Meanwhile, the energy source supply appliance can comprise an appliance energy source supply system and an appliance vehicle configured to transport the appliance energy source supply system. Further, the appliance energy source supply system can comprise an appliance energy source supply subsystem configured to receive the energy source from the hub energy source supply subsystem and to make available the energy source received to a receiver vehicle. Other embodiments of related systems, devices, and methods also are provided.

This invention is a sensor probe, generally used in the oil fracking business, and includes structurally a pair of tube members, concentrically assembled, an inner housing tube, and an outer spout tube, affixed to a cap and adaptor, with the inner housing holding one or more sensors, to detect the level of fuel within the fuel tank of the fracking truck. The adaptor has a first aperture for attachment of the fuel line, for delivery of fuel in the space between the tube members, and the adaptor has a second aperture for connection of an electrical receptacle, for attachment with the electric lines leading from the various sensors, to the adaptor, for connection with a circuit line from a remote monitor.

A fuel storage system is provided for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel at a vehicle. The fuel storage system including a main storage tank, an expansion tank, a fuel filling receptacle configured to receive a fuel filling nozzle of a filling station, and a valve arrangement having at least a normal operating setting and a fuel filling setting. The valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and the valve arrangement in the fuel filling setting both provides a fuel passage between the fuel filling receptacle and the main storage tank and prevents fuel flow between the main storage tank and the expansion tank. The fuel storage system is configured to mechanically prevent disconnection of the fuel filling nozzle from the fuel filling receptacle unless the valve arrangement is in the normal operating setting. A corresponding method, as well as a further example embodiment of the fuel storage system, are also provided.

A vehicle tank pressurization device has a valve seat establishing an opening for fuel vapours and/or air; such opening has a vertical axis coincident with the direction of application of an opening force, that is directed upwards and is produced, in use, by the pressure in an internal upper region of the tank; the device also has a movable shutter, placed on the valve seat, to open/close the valve seat, and having a weight set by design in such a way as to define the magnitude of a closing force directed downwards and with a center of gravity positioned eccentrically with respect to the vertical axis of the opening.
