ABSTRACT:
The invention is directed to a filling arrangement for filling and emptying an anesthetic vaporizer with an anesthetic liquid from a supply vessel via a filling channel and a venting channel. The filling arrangement includes a connecting piece for connecting the arrangement to the anesthetic vaporizer and has a blocking device mounted in a conduit member which includes the filling channel and venting channel. The filling arrangement is improved so that it can be reliably handled with anesthetic liquids having a low boiling point. For this purpose, the blocking device includes a temperature-sensitive switching member which enables the filling channel to be opened below a preselected limit temperature and to be closed above this preselected temperature. The preselected temperature is below the boiling point of the anesthetic liquid.
