Abstract
A vaporizer for vaporizing liquid anesthetic has a chamber for liquid anesthetic, a gas flow passage, a throttle in the gas flow passage, a first connection between the chamber and the gas flow passage upstream from the throttle and a second connection between the chamber and the gas flow passage downstream from the throttle. The vaporizer is more accurate and usable with different liquid anesthetics by having an outlet valve arranged by an outlet in the vaporizer, this outlet valve being regulated by the pressure upstream from the throttle.
