Abstract: Transportable device for storing and delivering oxygen includes a casing containing a cryogenic tank, a heating circuit connected to the tank including at least one member for heating/vaporizing the oxygen originating from the tank for the purpose of its being supplied to a user, a circuit for filling the cryogenic tank including a fluidic connection member designed to be connected, in a filling direction, to a matching connector of a liquid oxygen reserve, a venting valve connected inside the tank, a manually actuated movable member for controlling the venting valve, the control member being movable relative to the casing for actuating the valve via a system for transmitting movement between closed and open positions of the venting valve so in moving from closed to open positions, the control member describes a movement having at least one component oriented substantially towards the inside of the casing and/or in the filling direction.

Abstract: A transportable device for storing and delivering oxygen includes a casing (3) containing a cryogenic tank (1) designed to contain liquid oxygen, a heating circuit connected to the tank (1) including at least one member (2, 12) for heating/vaporizing the oxygen originating from the tank (1) for the purpose of its being supplied to a user. The device includes a pedestal (4) furnished with at least one rolling member (5) for allowing the displacement by rolling of the device, the pedestal (4) and the casing (3) including conjugate coupling members (6, 16; 7, 17) displaceable between an active position of locking of the casing (3) on the pedestal (4) and an inactive position of unlatching of the casing (3) relative to the pedestal (4).
