A coupling system (2A) for transferring liquid anaesthetic from a bottle to a vaporiser, comprising a first part (2A), comprising a first valve with a first spring-loaded valve body (8A, 10) and a first counter body (12A), and a second valve part, comprising in the corresponding fashion, a second valve with a second spring-loaded valve body and a second counter body, the first part (2A) and the second part being interconnectable, whereby the first counter body (12A) is devised to act on the second spring-loaded valve body in an opening direction, and the second counter body is devised to act on the first spring-loaded valve body (8A, 10) in an opening direction to form a path of flow for the liquid anaesthetic. Leakage of liquid into atmosphere is reduced since the first spring-loaded valve body (8A, 10) and the first counter body (12A) are arranged so they, in a closed position, form an essentially flat first surface, and the second spring-loaded valve body and the second counter body are arranged in the corresponding way so they, in the closed position, form an essentially flat second surface. <IMAGE> |
