Abstract
The invention relates to an arrangement for overfill protection of a container for anaesthetic liquid, comprising a liquid conduit for supplying anaesthetic liquid to a container for vaporization, and a gas conduit for withdrawing a volume of gas equivalent to the filling of anaesthetic liquid from the container. To prevent overfilling of the container, the liquid conduit from a feed point for anaesthetic liquid to the container comprises an inclined duct portion having an inlet through which the anaesthetic liquid is passed to the inclined duct portion and an outlet through which the anaesthetic liquid is passed out from the duct portion and further to the container. A body is positioned in the inclined duct portion such that said body can move in the inclined duct portion from a first position to a second position and vice versa, depending on the inclined position of the container, said body being adapted to move in front of the outlet when the container is tilted and to shut the outlet.
