Abstract

In an unplumbed sterilizer, a measured quantity of liquid is introduced into a partially evacuated chamber in a dump period. The liquid quantity is automatically controlled by closing a valve in the additional conduit upon the occurrence of either (a) the chamber pressure attaining a preset value, or (b) elapsing of a preset time, whichever occurs first.
