Abstract

A device for mixing anesthetic vapor with a gas according to the bypass principle such that anesthetic gas or liquid anesthetic is prevented from escaping from the evaporator chamber during transportation. The switching on of the anesthetic evaporator takes place under defined pressure conditions in the evaporator chamber. A transport position, which precedes the switch-off position, and in which a ventilating valve of a ventilating line arriving from the evaporator chamber is switched into the switch-off position by the setting member, is provided on the setting member.
