<p>A liquid reservoir comprising a container (2) forming a chamber for holding the liquid (15). The container (2) has a top wall (3) that closes the upper end of the chamber, an outlet port (8) in fluid communication with a lower end of the chamber, and an air supply port (5) through which air can enter the lower end of the chamber. In use the reservoir finds an equilibrium position in which, due to a reduction in pressure in an air space (10) formed above the liquid (15) at the closed, upper end of the chamber, the column of liquid in the chamber is supported by atmospheric pressure acting at the liquid/air interface (7) present at the opening of the air supply port (5) to the lower end of the chamber.</p> |
