Abstract
An arrangement for preventing overfill of an anaesthetic liquid container of a vaporizer resulting from inclination, comprising a bent intermediate container for guiding anaesthetic liquid to the anaesthetic liquid container for vaporization and for removing a volume of gas equivalent to the filling of anaesthetic liquid from the anaesthetic liquid container. The intermediate container is arranged to form a common conduit for the anaesthetic liquid and the gas removed from the container, and to combine the liquid flow outlet level and the gas flow outlet level in such a way that the anaesthetic liquid is allowed to flow into the anaesthetic liquid container only when the liquid flow outlet level is below the gas flow outlet level. The bent intermediate container may be located interiorly of, or exterior to, the anaesthetic liquid container.
