Abstract
A locking device 5 for a metering device 3 of an anesthetic vaporizer 1 with an unlocking device 6 for actuating the metering device 3 is provided so as to ensure blocking of the unlocking device 6 in operating states that are unsuitable for the operation of the anesthetic vaporizer 1. The locking device 5 is provided having a final control element 20, 24, 29 that covers a regulating distance that depends on a parameter influencing the operating state of the anesthetic vaporizer 1. This regulating distance of the final control element is transmitted to a blocking device 13 which blocks the unlocking device 6 if the values of the parameter are unsuitable for the operation of the anesthetic vaporizer 1.
