An intelligent pressure management system that controls the pressure inside a cryogenic tank between variable target vapor pressure values and/or ranges that are set as a function of system operating conditions, by actuating an actively controllable valve disposed on a gaseous fluid vapor conduit; and in some embodiments, additionally by actuating an actively controllable valve on a liquefied gaseous fluid conduit, based on a signal received from a pressure sensor that measures the pressure inside the pressurized tank. The variable target vapor pressure values and/or ranges are determined as a function of at least two system operating conditions which can include the vapor volume in the storage space; the fluid flow demanded by the use device; and a measured temperature parameter that correlates to the temperature of the fluid exiting a heater.

A valve for a pressurized fluid tank including a body housing a withdrawal circuit including an upstream first end designed to communicate with a pressurized fluid storage volume and a downstream second end designed to be connected to a downstream member using a withdrawn fluid, the withdrawal circuit including a regulation member for regulating the flow rate and/or the pressure of the withdrawn fluid between the upstream and downstream ends.

The present invention provides a control system (10) for managing the supply of bottled gas to users (12), the system comprising: a gas cylinder system (14) having a gas cylinder (15) for receiving and distributing gas contained therein; a first electronic monitoring system (16) associated with said gas cylinder system (14) and operable to monitor parameters associated with said cylinder system (14); a second monitoring system (18) associated with one or more locations (A-F) in which said cylinder may reside and being operable to monitor the presence or absence of said cylinder within said one or more locations (A-F); and a computer system (20) in communication with each of said second monitors (18) for receiving information therefrom relating to the presence or absence of said cylinder system (14) in said one or more locations (A-F).

The present invention provides a gas cylinder system (14) having a gas cylinder (15), a first electronic monitoring system (16) operable to monitor cylinder specific data (CSD) associated with said cylinder (15) or a patient specific data (PSD) associated with a patient. Such a cylinder system (14) may be used in a number of ways such as to modify the delivery of gas to a patient.

A valve assembly for pressurized containers includes a main structure, a rotary control element rotatably connected to the main structure and configured so as to allow a gas flow through the valve assembly in accordance with an angular position thereof about a main rotation axis, a detection device which includes an angular position sensor and a movable member. The angular position sensor is configured to detect the angular position of the movable member about an auxiliary rotation axis. The movable member is rotatably supported on the main structure and the angular position sensor is fixed to the main structure. The valve assembly further includes a movement conversion mechanism configured so as to convert the movement of the rotary control element about the main axis into a corresponding rotational movement of the movable member about the auxiliary axis which is different with respect to the main rotation axis.

A low-emission nozzle and receptacle coupling for cryogenic fluid is disclosed. A nozzle includes a body, a shaft, a poppet eat, and a poppet. The body includes an outer shell, body segment(s), and interior walls sealingly coupled together. At least one of the interior walls is coupled to the outer shell. The interior walls extend longitudinally back-and-forth in a zig-zag pattern to define an elongated conduction path between the chamber and an exterior of the nozzle to impede a heat leak between the chamber and the exterior. The shaft is housed within and slidably extends through the chamber. The poppet is coupled to the shaft and is configured to engage a receptacle poppet when the receptacle is coupled to the nozzle. The poppet is configured to engage the poppet seat in a closed position and be disengaged from the poppet seat in an open position.

Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

Gas supply device, comprising a frame equipped with a base and accommodating a plurality of pressurised fluid cylinders connected to a fluidic circuit comprising a first connection end connected to the cylinders and a second end comprising at least one fluidic connection intended to be connected removably to an extraction or filling element for the cylinders, the frame comprising on one of its faces at least one opening giving access to at least one connection of the circuit, the frame also comprising at least one attachment element provided to cooperate with a lifting device.
