- the encapsulated device In order to ensure safe operation of the compressor device, therefore, the encapsulated device must be protected at least mechanically. This is done by ensuring that the pressure of the process gas is at least equal to, but preferably always higher, than the pressure within the encapsulated device.
- the interior of the encapsulated device fluidly connected to a pressure reducing device, in particular via a fluid-conducting connecting line with the space outside the gas-tight pressure vessel.
- this connecting line opens directly into the atmosphere, so that it is ensured that the pressure in the interior of the encapsulated device is equal to the atmospheric pressure or does not rise significantly above atmospheric pressure.
- said connecting line opens into a controllable valve in order to control the pressure reduction, for example to the atmosphere, via the valve.
- the pressure in the interior of the encapsulated device and the pressure in the interior of the pressure vessel can be measured, and the valve, for example, be operated such that the pressure in the interior of the encapsulated device is always lower than the pressure of the process gas in Interior of the pressure vessel and, for example, has a constant pressure difference.

Nebst oder an Stelle des Elektromotors 31 können auch andere Komponenten wie die Magnetlager 32 in der bereits erläuterten gekapselten Vorrichtung 4 angeordnet sein, wobei in Figur 1 weder die elektrische Zuleitung noch die beispielsweise in ein Medium eingegossenen elektromagnetischen Spulen der Radialmagnetlager 32 dargestellt sind. Auch diese gekapselten Vorrichtungen 4 weisen eine Druckminderungsvorrichtung 34, hier als Verbindungsleitung 8 dargestellt, auf, um den Druck in der gekapselten Vorrichtung 4 zu begrenzen. Die in Figur 1 dargestellten Verbindungsleitungen 8 münden beispielsweise in die Atmosphäre.
Eine weitere Möglichkeit ein Eindringen von Prozessgas in den Innenraum 6 der gekapselten Vorrichtung 4 festzustellen besteht darin, im Innenraum 6 den Druck mit einem Sensor 11 zu messen. In einer weiteren Ausführungsform könnte zusätzlich noch mit einem Sensor 12 der Prozessdruck und/oder mit einem Sensor 26 der Umgebungsdruck gemessen und der Regelvorrichtung 14 zugeführt werden. Das Ventil 9 wird von der Regelvorrichtung 14 beispielsweise derart betätigt, dass der Druck im Innenraum 6 der gekapselten Vorrichtung 4 immer unterhalb dem im Innenraum 1a des Druckgehäuses 1 anliegenden Prozessdruck liegt, bzw. dass der Druck im Innenraum 6 tiefer ist als im Innenraum 1a.
Eine weitere Möglichkeit den Druck im Innenraum 6 der gekapselten Vorrichtung 4 zu reduzieren besteht darin, einen Pufferbehälter 16 vorzusehen, welcher über die Druckminderungsvorrichtung 37 Fluid leitend mit dem Innenraum 6 verbindbar ist. Der Pufferbehälter 16 könnte innerhalb oder ausserhalb des Druckgehäuses 1 angeordnet sein. Im Beispiel gemäss Figur 2 könnte die Druckminderungsvorrichtung 37 die Verbindungsleitungen 8 und 10, das Ventil 9 sowie die Leitung 20 und den Pufferbehälter 16 umfassen, welche Fluid leitend verbindbar sind. Der Pufferbehälter 16 weist zudem eine flexible und dichte Membran 17 auf, und ist über eine Leitung 19 und eine Durchbrechung 18 mit dem Innenraum 1a des Druckgehäuses 1 verbunden ist. Mit dieser Druckminderungsvorrichtung 37 kann durch eine entsprechende Ansteuerung des Ventils 9 sichergestellt werden, dass der Druck innerhalb des Innenraumes 6 nicht über den Druck im Innenraum 1a ansteigt sondern maximal den gleichen Wert wie im Innenraum 1a aufweist. Dies ist insbesondere wichtig, wenn der Druck im Innenraum 1a sinkt.
Das Ventil 9 oder auch die gesamte Druckminderungsvorrichtung 37 kann innerhalb des Druckgehäuses 1 angeordnet sein, oder wie in Figur 2 dargestellt, im wesentlichen ausserhalb des Druckgehäuses 1 angeordnet sein.
Die Leitung 19 des Pufferbehälters 16 könnte auch, an Stelle der Verbindung in den Druckbehälter 1, einen Auslass in die Umgebung bilden, beispielsweise in die Atmosphäre oder in das den Druckbehälter 1 umgebende Wasser. Der Druckbehälter 1 sowie die darin angeordneten Komponeten sind insbesondere auch zum Betrieb unter Wasser geeignet.
