[Problem] When configuring a device for storing and supplying fluid, each components such as vessels, valves/pipes and the like, are placed independently outside a vessel that stores the fluid, and even if these components are small, the volume of the area between the components cannot be effectively used because each of them occupies the surrounding area, and when the total size of the device is limited, it is difficult to ensure a sufficient volume of the vessel that stores the fluid. The present invention provides a design for a configuration of a mechanism consisting of components such as valves/pipes and the like, that functions for storing and exhausting the fluid inside the storage vessel to innovatively improve the volume usage efficiency of the device.

End fitting for a pressurized fluid reservoir, the reservoir comprising a liner (2) which comprises a tubular central portion (20) with a first cylindrical outer surface (21), characterized in that the end fitting (1) comprises an end portion (10) with a second cylindrical outer surface (11), the end portion (10) being configured to be positioned coaxially with respect to the tubular central portion (20), the second cylindrical outer surface (11) forming a radially flush extension of the first cylindrical outer surface (21), the end fitting (1) being configured to be mounted in a sealed manner on the outside of a neck (22) of the liner (2) by means of an annular sealing joint (4) arranged coaxially with respect to the end portion (10) in an annular groove (12) provided in an inner recess (13) of the end fitting (1) such that the internal pressure in the reservoir has a tendency to push the neck (22) radially outwards against the annular sealing joint (4).

A pressure vessel made of two thin-walled, closed-end tube sections joined at a central hub that encircles the open ends of the two closed-end tube sections, with a plurality of radial bolts attaching the sections together. The central hub has an O-ring groove in which an O-ring rests, providing a seal between the interior of the pressure vessel and the outside. The inner wall of the central hub may have radially thin and radially thick sections to distribute and minimize weight without sacrificing strength. The assembly may be attached to a mounting surface through a dovetail mount on the central hub.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with an exhaust nozzle corresponding to a vehicle exhaust port. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. A first pipe may be configured to transport captured exhaust therethrough from the exhaust nozzle to. The captured exhaust may be at least temporarily stored in an exhaust holding tank connected to and in fluid communication with the first pipe.

A valve for a fluid reservoir includes an inner portion configured to be arranged inside the reservoir, the inner portion including at least one portion of a sensor for measuring at least one parameter characterizing the fluid, the valve being capable of receiving information from a computer, external to the valve, the valve also includes an outer portion configured to be arranged outside the reservoir, the outer portion having an internal computer that acquires data from the at least one sensor, communicates bidirectionally with the external computer, takes into account information received from the external computer and data from the at least one sensor for controlling at least one actuator of the valve, and measures at least one current parameter in the electrical connection.

An automatic obstruction device for closing a filling circuit for filling a tank with fluid includes: a movable element movable between a non-obstruction position of the filling circuit, in which the movable element offers resistance to the fluid compatible with the filling of the tank, and an obstruction position of the filling circuit, in which the movable offers a resistance to the fluid that is incompatible with the filling of the tank; a holding element of the movable element holding the movable element in the non-obstruction position, and allowing movement of the movable element toward the obstruction position; and a first device of non-reversible movement or of non-reversible modification of the holding element allowing movement of the movable element toward the obstruction position, and being controllable by a control device.

The invention relates to a method for filling a hydrogen tank (2) of a motor vehicle (1) comprising a fuel cell drive, wherein the method comprises the steps: (a) determining a first operating time at which the motor vehicle (1) is to be started up and an expected first operating location at which the motor vehicle (1) is to be started up, (b) ascertaining a predicted maximum ambient temperature (T.sub.U,max) at the first operating location at the first operating time, and (c) filling the hydrogen tank with hydrogen (3) until a tank pressure (p) in the hydrogen tank (2) reaches a maximum permissible tank pressure (p.sub.max) at a tank temperature (T), wherein the following applies for the tank temperature (T): tank temperature (T)=[maximum ambient temperature (T.sub.U,max); maximum ambient temperature (T.sub.U,max)+10 K]. The invention relates further to a motor vehicle (1) comprising a hydrogen tank (2), a fuel cell drive and a control system (5) for controlling filling of the hydrogen tank (2), wherein the control system (5) to carry out the method.

A regulating valve device for a fluid cylinder includes a shut off valve having a ball tappet that actuates the shut off valve. A lever has a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly and actuate the shut off valve. The lever is rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position is intermediate of the first and second valve closed positions. A pressure or flow regulating valve is downstream of the shut off valve. A handwheel is operatively connected to the pressure or flow regulating valve to adjust an outlet pressure of the pressure or flow regulating valve. The handwheel has an axis of operation that is offset from a longitudinal axis of the fluid cylinder by an acute angle.

A motor vehicle includes at least one pressure vessel for storing fuel, and at least one holder for holding the pressure vessel. When installed, the holder encloses one end of the pressure vessel. The holder has a hard shell and an inner layer, wherein at least regions of the inner layer, when installed, are arranged between the hard shell and the connecting element. The hard shell has a higher rigidity than the inner layer.
