To prevent deterioration of a sealing structure of a filling device to decrease a possibility that hydrogen gas leaks. In filling devices (100, 101) including a storage tank for storing hydrogen fuel and filling nozzles (10, 11) for filling hydrogen from the storage tank through a fuel filling system (dispenser, filling hose and so on) to an in-vehicle hydrogen filling tank mounted on a vehicle, in a pipe joint main body (1) of the filling nozzles (10, 11) is slidably arranged a rod (2: valve rod) having a valve element at its end against an elastic member (3).

To provide a filling nozzle that can be disconnected from a receptacle even if a clutch becomes difficult to disengage. A filling nozzle 10 according to the present invention is characterized by including: a pipe joint body 1 provided at a tip of a filling hose for filling gaseous fuel and connected to a receptacle 20 on a side to be filled with gaseous fuel; a clutch 4 that extends on an outside of the pipe joint body 1 in a direction in which the pipe joint body 1 and the receptacle 20 are connected (hereinafter referred to as connection direction) and engages with the receptacle 20; a lever 5 that extends on an outside of the clutch 4 in the connection direction and restricts a movement of the clutch 4 in the connection direction when the gaseous fuel is filled; and an urging means interposed between the lever 5 and the clutch 4 or between the pipe joint body 1 and the clutch 4, wherein the urging means urges the clutch 4 inward in a direction perpendicular to the connection direction to release the restriction in movement of the clutch 4 in the connection direction when filling of the gaseous fuel is completed.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

The present invention relates to a fuel oil theft prevention tool configured to prevent theft or siphoning of fuel oil from a fuel tank. The tool is compact and lightweight and includes a metal femalefemale reduced coupling, a heavy-duty metal screen having a plurality of holes disposed therein, the screen is positioned inside the reduced coupling and is secured/biased and held tight by a torsional spring, a malefemale hex bushing having a hexagonal head is positioned inside the reduced coupling over the screen for further securing of the screen. The tool is positioned between the fuel delivery pipe and the supply pipe and is configured to allow flow of fuel oil in only one direction.

A method is provided for refueling a motor vehicle. The method include the steps of: acquiring at least one signal, wherein the signal contains information as to whether the motor vehicle has at least one device for preventing follow-up refueling; and providing fuel in accordance with the acquired signal.

The invention relates to a valve for a pressurized fluid cylinder comprising a draw off circuit, a data acquisition, storage, and processing member, at least one display and a pressure sensor for measuring the pressure within the storage space of a fluid cylinder connected to the valve. When the variation of the signal representing the fluid pressure measured by the pressure sensor is greater than a specific draw off threshold, the data acquisition, storage and process member is designed to detect the drawing off of gas and, in response, to control the displaying on the display of at least one item of information concerning the draw off.

The invention relates to a valve for a pressurized fluid cylinder comprising a member for manually controlling a flow-regulating member, a sensor for detecting the position of the member for manually controlling the regulating member, a data acquisition, storage, and processing member, and a display for information relating to the fluid flow and/or pressure imposed by the regulating member and/or the valve use mode, wherein when the manual control member is disposed in an intermediate position between two respective adjacent values of the flow and/or pressure of the fluid allowed to pass from the upstream end to the downstream end, the data acquisition, storage and process member is designed to suppress the display information.

The invention relates to a pressurized fluid cylinder, a member for acquiring, storing and processing data, and at least one data display device. The valve comprises a sensor which detects the position of a manual control member, and a pressure sensor for measuring the pressure inside the storage space of a fluid cylinder. The data acquisition, storage and processing member is designed to: calculate an actual value for the amount of fluid remaining and/or drawn off; calculate a theoretical value for the amount of fluid remaining and/or drawn of on the basis of the regulation performed by the regulating member and measured by the position of the control member compare the actual value based on the measurement of the pressure sensor with the theoretical value; and generate a warning signal if the difference between these actual and theoretical values is greater than a specific safety threshold.
