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.

A metering device for attaching to a container configured to store a fluid, the device including: a valve configured to control the amount of fluid dispensed from the container; a user interface comprising at least one control configured to operate the valve between an open position and a closed position; and a control circuit configured to set a threshold amount of the fluid to be dispensed from the container, where the control circuit is configured to override the user interface and close the valve when the threshold amount of fluid to be dispensed has been reached.

The present invention relates to devices, systems, and methods for a safety interlock for a gas cylinder. The interlock device of the present invention can prevent a gas cylinder from being removed from a gas administration device as long as gas remains in the gas cylinder.

The invention is directed to a valve for a compressed gas cylinder, comprising: a valve body with an inlet, an outlet and a passage connecting the inlet with the outlet; a shut-off device of the passage with an actuating pin extending in the passage; a check-valve between the shut-off device and the inlet, the check valve comprising a seat and a movable closing member initially held at a position distant from the seat by contact with a guiding surface and movable past the position by the pin so as to cooperate with the seat and prevent a refilling flow of gas from the outlet to the inlet. The guiding surface is on a tubular portion fixed to the valve body and comprising at least one radial aperture so as to allow the refilling flow of gas to by-pass the closing member when in the distant position.

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 invention relates to a gas supply device including a supporting frame (2) housing a plurality of cylinders (3) connected such as to form a circuit (4, 5) including a first coupling end (6) connected to the cylinders (3) via a first isolation valve (7) and a second separate coupling end (8) that is connected to the cylinders (3) via a second isolation valve (9) and a pressure release valve (10), the supporting frame (2) including an interface panel (20) comprising at least one opening enabling a user to access the circuit (4, 5), characterized in that the device comprises a member (16) for manually controlling the second isolation valve (9) including a pivoting lever, and in that the interface panel (20) includes a slot (21) for accessing the lever (16), said lever (16) being movable between a first position in which the lever (16) is in the plane of the interface panel (20) or set back from the latter within the volume of the frame (2) and a second position in which at least one portion of the lever (16) projects relative to the interface panel (20) through the slot (21).

A fitting for a liquid gas bottle with a gas consumer connection piece, with a gas inlet opening on the underside, with a gas conducting connection between the gas inlet opening and the gas consumer connection piece, with a rotary handle, which can be turned into an open position and into a closed position, wherein in the open position gas can flow from the gas inlet opening to the gas consumer connection piece and in the closed position no gas can flow from the gas inlet opening to the gas consumer connection piece, with a closable opening on the upper side of the fitting, with a gas conducting connection which connects the closable opening on the upper side with an opening at the underside in such a way that refilling a connected gas bottle with gas through the underside and through the closable opening is possible, characterized in that the edge of the closable opening is part of the rotary handle.
