An anaesthetic vaporiser (1) of the by-pass type includes a thermally responsive valve (52) in its second by-pass stream which valve (52) is located immediately below the sump (12) of the vaporiser. This offers the advantage that any difference in temperature between the valve (52) and liquid anaesthetic contained in the sump (12) is very small even when the liquid anaesthetic temperature is changing rapidly. Furthermore, the valve (52) is readily accessible for maintenance and calibration. |
