<p>An apparatus for conveying liquids (2) of which the vapour pressure is above atmospheric at ambient temperature, comprises a storage container (1) and a delivery point (17). Between these there is a pump (12) preceded by cooling apparatus (10). Its temperature (t2) is held at least somewhat lower than the container temperature (t1). In this way, one ensures that the pump (12) will always deliver liquid. Single figure.</p> |
