FLUID CONDUIT ARRANGEMENT

摘要

A fluid conduit arrangement (10) includes a reservoir (12) containing a pressurized gas (14) therein. An outer rigid conduit (16) in communication with the reservoir (12) contains a first working fluid under pressure from the pressurized gas within a closed system defined by the reservoir (12) and the outer rigid conduit (16). An inner flexible conduit (18) is provided for conducting a second working fluid therethrough upon application of a supply pressure. The inner flexible conduit (18) is disposed within the outer rigid conduit (16), and is subjected to the pressurized first working fluid in surrounding relationship therewith. Relative differences between the pressurized first working fluid and the second working fluid enable the inner flexible conduit (18) to either expand and permit free flow of the second working fluid therethrough, or collapse and evacuate flow of the second working fluid therefrom.
