Abstract

Offenbart ist zum Einen ein Kreisprozess in einem Flüssigkolbenwandler mit abwechselndem Heben und Senken eines Flüssigkolbens in einem Arbeitsraum (15), der an einer Unterseite einen Flüssigkeitsanschluss für eine Flüssigkeit des Flüssigkolbens und an einer Oberseite einen Hochdruckanschluss (12) für ein Gas unter einem Hochdruck und einen Niederdruckanschluss (11) für das Gas unter einem Niederdruck aufweist, wobei in dem Kreisprozess eine Strömungsarbeit an der Flüssigkeit in eine Druckänderung des Gases oder die Druckänderung in die Strömungsarbeit gewandelt wird. Zum Andern ist ein solcher Flüssigkolbenwandler offenbart.Disclosed is, on the one hand, a cyclic process in a liquid piston converter with alternating lifting and lowering of a liquid piston in a working space (15) having at one bottom a liquid connection for a liquid of the liquid piston and at a top a high pressure connection (12) for a gas under a high pressure and a low pressure port (11) for the gas under a low pressure, wherein in the cyclic process a fluid flow on the fluid is converted into a pressure change of the gas or the pressure change into the fluid flow. For another, such a liquid piston converter is disclosed.

Um die Betriebssicherheit des Flüssigkolbenwandlers zu verbessern wird vorgeschlagen, dass der Flüssigkolbenwandler auf Senken des Flüssigkolbens umgeschaltet wird, wenn beim Steigen des Flüssigkolbens die Flüssigkeit in dem Arbeitsraum (15) ein Drosselelement (35), das für das Gas durchlässig und für die Flüssigkeit im Wesentlichen undurchlässig ist, erreicht und ein Druck in der Flüssigkeit vor dem Drosselelement (35) ansteigt. Der hierzu vorgeschlagene Flüssigkolbenwandler weist ein Drosselelement (35) in dem Arbeitsraum (15) auf, das für das Gas durchlässig und für die Flüssigkeit im Wesentlichen undurchlässig ist, ein Sensorelement zum Erkennen eines Druckanstiegs in der Flüssigkeit vor dem Drosselelement (35) und ein mit dem Sensorelement verbundenes Schaltelement, das bei Erkennen des Druckanstiegs mittels des Sensors den Flüssigkolbenwandler vom Heben auf Senken des Flüssigkolbens umschaltet.

Figure imgaf001
In order to improve the reliability of the liquid piston transducer, it is proposed that the liquid piston converter is switched to depressions of the liquid piston, when the liquid piston in the working space (15), a throttle element (35) permeable to the gas and for the liquid substantially during the rise of the liquid piston is impermeable, reaches and a pressure in the liquid before the throttle element (35) increases. The liquid piston converter proposed for this purpose has a throttle element (35) in the working space (15), which is permeable to the gas and substantially impermeable to the liquid, a sensor element for detecting a pressure increase in the liquid upstream of the throttle element (35) and with a the switching element connected to the sensor element which, upon detection of the pressure increase by means of the sensor, switches the liquid piston transducer from lifting to lowering of the liquid piston.
