Description

Vorrichtung zur Abkühlung und Verflüssigung von Luft und anderen ähnlichen Gasen und Gasgemischen. Die bisherigen bekannten Vorrichtungen zur Abkühlung und Verflüssigung von Luft und anderen ähnlichen Gasen und Gasgemischen mittels Expansionsmaschinen haben den Nachteil, daß (las t-entil für den Eintritt der Hochdruckluft in die Expansionsmaschine an dem Außenmantel des Zvlinders befestigt und durch einen Exzenter zwangläufig gesteuert wird. Bei diesem Ventil muß eine besondere Stopfbuchse angeordnet und sehr gut abgedichtet werden. Wegen des hohen Drukkes von Zoo Atin. und wegen der hier entstehenden großen Kälte ist eine solche Abdichtung mit einer Stopfbuchse sehr schwierig: dieselbe wird leicht undicht, so daß Hochdruckluft entweichen kann und dadurch an dieser Stelle Verluste von erzeugter Kälte entstehen.Device for cooling and liquefying air and other similar Gases and gas mixtures. The previously known devices for cooling and Liquefaction of air and other similar gases and gas mixtures using expansion machines have the disadvantage that (las t-valve for the entry of high pressure air into the expansion machine attached to the outer jacket of the cylinder and inevitably by an eccentric is controlled. With this valve a special stuffing box must be arranged and be sealed very well. Because of the high pressure at Atin Zoo. and because of the The resulting great cold is such a seal with a stuffing box very difficult: it leaks easily so that high pressure air can escape and thereby losses of generated cold occur at this point.

Die vorliegende Erfindung vermeidet diese Nachteile, indem das Ventil so angeordnet ist, daß es sich vollständig im Innern des Hochdruckraumes befindet, wobei alle beweglichen Teile des Ventiles von der festen Wandung des Expansionszylinders und der anschließenden Hochdruckleitung allseitig fest umschlossen sind, so daß keine beweglichen Teile des Ventiles aus dein Hochdruckraum nach außen führen, die Verwendung einer Stopfbuchse also entbehrlich wird. Zweckmäßig wird der bewegliche @"entilkörper in eine Erweiterung der Hochdruckrohrleitung vor dem Expansionszylinder angeordnet und ragt mit seinem Ende in letzteren hinein. wobei er durch eine Zentriervorrichtung, z. B. eine schwache Spiralfeder in der `% erschlußstellung gehalten wird. Die Öffnung des Ventiles wird durch den Vorschub des Kolbens bei dessen Hubwechsel und die Schließung des Ventiles durch die Hochdruckluft selbst bewirkt. Die richtige Einstellung des Ventiles kann durch eine geringe Veränderung des Kolbenhubes leicht bewirkt werden. Um den schädlichen Raum zwischen dein vorderen Kolbenende und der Zylinderwandung auf ein -Minimum zu beschränken, erhält das vordere Kolbenende die Form eines abgestumpften Kegels, dein sich auch die vordere Zylinderwand anpaßt.The present invention avoids these disadvantages by designing the valve is arranged so that it is completely inside the high pressure chamber, all moving parts of the valve from the fixed wall of the expansion cylinder and the subsequent high pressure line are firmly enclosed on all sides, so that no moving parts of the valve lead to the outside of your high-pressure chamber that Use of a stuffing box is therefore unnecessary. The movable one becomes useful @ "valve body in an extension of the high pressure pipeline in front of the expansion cylinder arranged and protrudes with its end into the latter. with a centering device, z. B. a weak spiral spring is held in the `% closed position. The opening of the valve is caused by the advance of the piston during its stroke change and the closure of the valve caused by the high pressure air itself. The correct setting of the Valve can easily be effected by a slight change in the piston stroke. Around the harmful space between your front piston end and the cylinder wall To restrict it to a minimum, the front end of the piston takes on the shape of a truncated one Cone to which the front cylinder wall adapts.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Ein Teil der Hochdruckluft gelangt durch das Hochdruckeinlaßventil L in den Expansionszylinder h:. Der bewegliche Teil M des Einlaßventils liegt in einer Erweiterung N der Hochdruckleitung. Das Ventil wird durch eine Zentriervorrichtung beliebiger Art, z. B. durch eine schwache Spiralfeder 0 zentriert und in Verschlußstellung gehalten und ragt finit seinem vorderen Ende zentral in den Expansionszylinder hinein. Nachdem das Ventil durch den Expansionskolben P bei seinem Vorschub geöffnet ist, schließt es sich beim Zurückgehen des Kolbens durch den Druck der Hochdruckluft von selbst; die Hochdruckluft expandiert, das Niederdruckventil0 öffnet sich zwangläufig und die kalte entspannte Niederdruckluft tritt in den Gegenstromapparat ein.An exemplary embodiment of the invention is shown in the drawing. Part of the high pressure air enters the expansion cylinder through the high pressure inlet valve L. H:. The movable part M of the inlet valve is located in an extension N of the high pressure line. The valve is centered by any type of centering device, e.g. B. by a weak spiral spring 0 centered and held in the closed position and protrudes finitely its front end centrally into the expansion cylinder. After the valve is opened by the expansion piston P during its advance, it closes when the piston goes back by the pressure of the high pressure air by itself; the high pressure air expands, the low pressure valve 0 inevitably opens and the cold one relaxed Low pressure air enters the counterflow apparatus.
