Abstract: A flow regulator comprising a body housing a gas duct comprising an upstream end configured to be connected to a gas source and a downstream end comprising an outlet connector and configured to be connected to a gas user with a regulated flow rate, the gas duct comprising a selective fluid flow regulation component for the gas circulating between the upstream and downstream end depending on the position of the control component with respect to the body, wherein the control component comprises a peripheral wall delimiting a central hollow volume and in that the outlet connector is situated within the central cavity.

Abstract: The invention relates to a coupling system for a gas container, in particular a gas cylinder (9), comprising a base (1) which is designed to be fixed on a support (10), wherein the base (1) comprises a first arm (3a) and a second arm (3b), at least one of which is mobile in pivoting relative to the other, and an activation unit (4) which co-operates with at least one of said first and second arms (3a, 3b), such as to pivot at least one of said first and second arms (3a, 3b) to bring them towards one another, when said activation unit (4) is activated. The invention also relates to a support/cylinder assembly comprising a coupling system of this type, and a gas cylinder (9) retained by the arms (3a, 3b) of said coupling system.

Abstract: The invention relates to a protective cap for gas container, comprising a cap body forming a protective shell delimiting an internal volume designed to accommodate all or part of the valve-assembly, and an attachment device able to pivot between several angular positions, comprising a rest position in which the attachment device is fully folded, and an attachment position in which the attachment device is completely unfolded. The attachment device comprises a three-dimensional structure comprising two arms each bearing a cutout for fixing to a support, the said three-dimensional structure comprising an interior face shaped to conform to the exterior profile of the body of the cap when the attachment device is in the rest position.
