ABSTRACT:
An anaesthetic vaporiser 1 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.
