Abstract

A pump has a compensating vessel 7 off the inlet duct 2 leading to the pumping chamber 6 between the pistons 4,5. In operation, liquid will find its way in to vessel 7 and some will automatically be given up when not enough to fill chamber 6 is supplied directly down duct 2. This is particularly useful when pumping low-boiling liquids such as anaesthetics which can vaporise under the low pressure of the inlet stroke. Preferably the vessel 7 is in the form of metallic bellows. <IMAGE>
