摘要： A compression and expansion system includes a pressure vessel having a variable volume working chamber therein. The pressure vessel has a conduit through which at least one fluid can be introduced into and discharged from the working chamber. The system further includes a heat transfer element disposed within the working chamber and including a layer and at least one of a fin and a spacing element. The pressure vessel is operable to compress fluid introduced into the working chamber such that heat energy is transferred from the compressed fluid to the heat transfer element, and is further operable to expand fluid introduced into the working chamber such that heat energy is transferred from the heat transfer element to the expanded fluid.

摘要： 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.
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.-

摘要： The aim of the invention is to provide a method for conveying flowable substances, whose implementation does not require adherence to any special supply prerequisites. To this end, a gaseous conveying medium subjects the substances to the action of pressure which is alternately changed between two pressure levels such that at a low pressure level, the substances continue flowing, and by applying the higher pressure level, are conveyed in the desired direction of conveyance.

摘要： The multi-chamber liquid pump of the present invention includes an input chamber, an intermediate chamber and a liquid output chamber. Pressurized gas provides the motive force for outputting liquid from the pump, such that liquid is output at a constant flow rate during pump operation. Liquid flows into the input chamber, through one or more valves into the intermediate chamber, and through one or more subsequent valves to the output chamber while liquid is constantly output from the output chamber. The system controller provides control signals to the valves to facilitate the pump's continual operation.

摘要： A method, system and apparatus that may be used for transferring a fluid such as molten metal, pure water, chemical liquid, and the like are disclosed. None of the functional mechanical parts or elements such as mechanical valves that require the mechanical motions, i.e., rotary, sliding, or other like motions are not included, and the fluid transferring and/or branching functions are instead implemented. The fluid transfer apparatus includes a fluid storing chamber, an air inlet/outlet means connected to the upper end of the fluid storing chamber, an inlet pipe having its open upper end connected to one lateral wall of the fluid storing chamber and having its open bottom end extending into the fluid being transferred through which the fluid is drawn into the fluid storing chamber by decreasing the pressure in the fluid storing chamber, and a U-shape outlet pipe through which the drawn fluid in the fluid storing chamber is transferred by increasing the pressure in the fluid storing chamber, wherein a part of the drawn fluid is allowed to remain in the U-shape outlet pipe when the pressure in the fluid storing chamber is decreased, and the other hand a part of the drawn fluid is further allowed to remain in the bottom end of the inlet pipe when the pressure in the fluid storing chamber is increased.

摘要： A pump (10) for pumping a slurry of frail material is provided by a rigid chamber (12) which is connected to a source of negative air pressure when an inlet valve (18) is open and an outlet valve (20) closed to suck the slurry through the open inlet valve into the chamber, the amount of slurry in the chamber is sensed and when it reaches a preset amount a controller (70) is triggered to disconnect the source of negative pressure and close the inlet valve (18), and then admit air under positive pressure to the chamber, then open the outlet valve (20) to drive the contents of the chamber (12) through the outlet by replacing a significant amount of the contents with air. The controller then causes the air pressure in the chamber to be reduced and closes the outlet valve (20), and then reconnects the chamber to the source of negative pressure and then opens the inlet valve to commence a second cycle. The inlet and outlet valves are bladder type valves to protect the frail material and permit simplified operation.
