Description

Verfahren zur Herstellung von vollkommen geschlossenen Gefäßen mit innerem Überdruck, insbesondere für Kältemaschinen Gemäß der Erfindung werden geschlossene Gefäße mit innerem Überdruck in der Weise hergestellt, daß der Druck im Innern des Gefäßes durch Abkühlen so weit herabgesetzt wird, daß die letzte Öffnung durch Verschmelzen, Verschweißen o. dgl. geschlossen werden kann.Process for the production of completely closed vessels with internal overpressure, in particular for refrigeration machines. According to the invention, closed Vessels with internal overpressure produced in such a way that the pressure inside the The vessel is lowered so far by cooling that the last opening by melting, Welding or the like. Can be closed.

Das Verfahren läßt sich bei Absorptionskältemaschinen um so leichter durchführen, als schon bei mäßiger Temperaturerniedrigung eine lebhafte Absorptionswirkung eintritt, durch die der Druck weitgehend herabgesetzt wird.The process is all the easier with absorption chillers perform, than a lively absorption effect even with a moderate decrease in temperature occurs through which the pressure is largely reduced.

Wenn bei diesem Vorgang der Innendruck im Gefäß so weit herabgesetzt wird, daß er geringer wird als der Außendruck, so preßt sich infolge des außen herrschenden Überdrucks das Abschlußstück an die Ränder der abzuschließenden Öffnung an, wodurch die Durchführung des Arbeitsverfahrens (Verschmelzen, -Verschweißen o. dgl.) wesentlich erleichtert wird. Das Verfahren gemäß der Erfindung ermöglicht es, Druckgefäße herzustellen und abzuschließen, deren Wandung ein einziger, möglichst einheitlicher Körper ist.If during this process the internal pressure in the vessel is reduced so much If it becomes less than the external pressure, it is pressed as a result of the external pressure Overpressure the end piece to the edges of the opening to be closed, whereby the implementation of the work process (fusing, welding, etc.) is essential is facilitated. The method according to the invention makes it possible to manufacture pressure vessels and to complete, the wall of which is a single, as uniform as possible body.

PATENTANSPRUCH: Verfahren zur Herstellung von Absorptionsmaschinen, in denen bei der Temperatur des umgebenden Raumes innerer Überdruck herrscht, dadurch gekennzeichnet, daß beim Verschließen der letzten Öffnung durch Verschweißen, Verschmelzen o. dgl. die in der Absorptionsmaschine enthaltene Absorptionslösung so weit abgekühlt wird, daß infolge der dabei eintretenden Absorption von gasförmigem Arbeitsmittel der innere Überdruck verschwindet. - PATENT CLAIM: A process for the production of absorption machines in which internal overpressure prevails at the temperature of the surrounding space, characterized in that when the last opening is closed by welding, fusing or the like, the absorption solution contained in the absorption machine is cooled to such an extent that as a result the resulting absorption of gaseous working medium, the internal overpressure disappears. -
