Abstract
An expressor for varying the amount of fluid in a variable-volume container connected to at least one conduit includes a housing defining an enclosed chamber which can accommodate the container. The housing has at least one opening through which a conduit can extend. A pressure regulating mechanism is coupled to the housing to vary the pressure of fluid in the chamber and thereby vary the volume of the container.
