PRESSURE CONTROLLED CHAMBER

A pressure controlled chamber arrangement comprising a chamber (82), one or more seals (90) arranged in use to limit fluid flow between the inside and outside of the chamber and a vent system (96) arranged in use to remove a vent flow of fluid from the inside of the chamber. The vent system at least...

Beschreibung
Zusammenfassung:	A pressure controlled chamber arrangement comprising a chamber (82), one or more seals (90) arranged in use to limit fluid flow between the inside and outside of the chamber and a vent system (96) arranged in use to remove a vent flow of fluid from the inside of the chamber. The vent system at least contributes to the formation of a pressure drop across the one or more seals from the outside to the inside of the chamber. The vent system comprises a flow controller (60) arranged in use to control the quantity of fluid removal via the vent system in accordance with the sealing performance provided by the one or more seals, the vent system giving increased quantity of fluid removal for decreased sealing performance.
