<p>A filling device on a container for filling the same with a liquid gas comprises two parts adapted to be coupled to each other, the first of these parts being secured to the container and provided with two check valves having distinct flow paths which begin within the container at a certain level in the upper portion thereof. The second of said two parts comprises means for opening both check valves when the two parts are coupled together, and two separate passageways for liquid gas forming continuations of said two distinct flow paths, the first of said passageways being controlled by a valve which is responsive to the presence of liquid gas in the passageway and the second passageway being adapted for connection to a supply conduit for liquid gas. The first passageway may be connected to a suction pump whereby liquid gas is drawn through said supply conduit and the second passageway into the container until said valve responsive to the presence of liquid gas closes the connection of the first passageway with the suction pump.</p> |
