摘要

A stopcock comprises a hollow barrel 2 which receives in a rotatable manner a cooperating tap 22. A section 30 of the tap 22 is formed with holes 32 which allow communication between selected hollow spigots 4, 6, 8 extending from the barrel 2. A further section 28 of the tap 22 of larger diameter than the section 30 is formed with indents which engage with detents 14 formed on a large diameter section 12 of the barrel 2 to provide a positive indication when the tap 22 is rotated within the hollow barrel 2 to one or more selected positions.
