Abstract

The converter has a flexible sleeve (5) and a pressure build-up system which is filled with the medium which is to be pressurised. The converter is set in the gas pressure supply container where it reduces the gas volume same and is kept constant above the minimum working pressure. If the pressure in the supply container rises above the minimum working pressure, the internal converter reduces in size through the flexible sleeve and the increasing external pressure, thereby releasing the volume for more compressed air. The flexible sleeve is prevented from stretching excessively through a surrounding air-permeable plastic fibre sleeve (4).

Description

Der interne Gasdruckkonverter ist ein flexibler Körper zum schnelleren Druckaufbau in Gasdruckvorratsbehältern.The internal gas pressure converter is a flexible body for faster pressure build-up in Gas pressure reservoirs.

Bei gasdruckabhängigen Geräten verstreicht grundsätzlich Zeit zwischen der Inbetriebnahme des Gasdruckerzeugers bis zum Erreichen des nötigen Arbeitsdrucks im Gasdruckvorratsbehälter. Z. B. ein Kompressor erzeugt Druckluft für eine Presse. Minimum-Arbeitsdruck der Presse liegt im Beispiel bei 8 bar, der Luftkessel hat ein Volumen von 60 Litern. Vor Inbetriebnahme des Kompressors herrscht im Luftkessel ein Druck von 0 bar. Bevor die Presse arbeiten kann, müssen im Luftkessel 8 bar herrschen, das bedeutet, daß der Kompressor vor Arbeitsbeginn 480 Liter Luft in den Luftkessel pumpen muß.In the case of devices dependent on gas pressure, the time generally lapses between commissioning of the gas pressure generator until the required working pressure is reached in the gas pressure reservoir. For example, a compressor generates compressed air for a press. Minimum working pressure of the press is in the example at 8 bar, the air boiler has a volume of 60 liters. Before starting the compressor there is a pressure of 0 bar in the air tank. Before the press can work, it must be in the air tank There is 8 bar, which means that the compressor has 480 liters of air in the air boiler before starting work must pump.

Um diesen Aufwand zu verkleinern, habe ich den internen Gasdruckkonverter erfunden. Der interne Gasdruckkonverter wird in den Gasdruckvorratsbehälter eingesetzt, wo er das Volumen des Gasdruckvorratsbehälters verringert, wobei der interne Gasdruckkonverter selbst konstant über den Minimum-Arbeitsdruck verfügt. Steigt der Druck im Gasdruckvorratsbehälter über den Minimal- Arbeitsdruck an, verkleinert sich der interne Gasdruckkonverter aufgrund seiner flexiblen Hülle und des wachsenden Außendrucks und gibt so Volumen für mehr Druckluft frei.In order to reduce this effort, I invented the internal gas pressure converter. The internal gas pressure converter is inserted into the gas pressure reservoir, where it measures the volume of the gas pressure reservoir is reduced, the internal gas pressure converter itself constantly above has the minimum working pressure. If the pressure in the gas pressure reservoir rises above the minimum Working pressure, the internal gas pressure converter is reduced due to its flexible shell and the growing external pressure and thus releases volume for more compressed air.

Im Beispiel bedeutet dies: Von den 60 Litern Luftkesselvolumen belegt der interne Gasdruckkonverter 50 Liter mit einem Innendruck von 8 bar, somit sinkt das zu befüllende Volumen auf 10 Liter, was bedeutet, das anstelle von 480 Liter Luft nun nur noch 80 Liter Luft bis zum Erreichen des minimalen Arbeitsdrucks vom Kompressor in den Luftkessel gepumpt werden muß. In the example, this means that the internal gas pressure converter occupies 60 liters of the air boiler volume 50 liters with an internal pressure of 8 bar, so the volume to be filled drops to 10 liters, which means instead of 480 liters of air now only 80 liters of air until the minimum working pressure is reached must be pumped from the compressor into the air tank.  

Beschreibung der ZeichnungenDescription of the drawings

Die Zeichnungen weisen die zwei wesentlichsten Arbeitsmomente des internen Gasdruckkonverters auf.The drawings show the two most important working moments of the internal gas pressure converter.

In der Abb. 1 herrscht im Gasdruckvorratsbehälter 3 ein Druck unterhalb des Arbeitsdrucks. Der interne Gasdruckkonverter hat unter dem internen Druck seine volle Größe erreicht und füllt des Gasdruckvorratsbehälter zu 90% aus. Das Ventil 8 ist unter dem inneren Druck geschlossen und verhindert, daß der Innendruck d7 sich in den Gasdruckvorratsbehälter fortpflanzt. Um ein Überdehnen der flexiblen Hülle 5 zu verhindern, umgibt den internen Gasdruckkonverter eine luftdurchlässige Kunstfaserhülle 4.In Fig. 1 there is a pressure in the gas pressure reservoir 3 below the working pressure. The internal gas pressure converter has reached its full size under the internal pressure and fills the gas pressure reservoir to 90%. The valve 8 is closed under the internal pressure and prevents the internal pressure d7 from propagating into the gas pressure reservoir. In order to prevent the flexible sheath 5 from overstretching, the internal gas pressure converter is surrounded by an air-permeable synthetic fiber sheath 4 .

In der Abb. 2 hat der Gasdruckvorratsbehälter sein maximales Druckniveau erreicht und der flexible interne Gasdruckkonverter hat sein Volumen unter dem hohen Außendruck so weit reduziert, daß die beiden Druckaufbaukammern 6 aneinanderliegen, um in Verbindung mit dem Ventil 8 das Innendruckniveau d7 an das Außendruckniveau anzugleichen, beginnt der Gasdruckkonverter sich unter der Entspannung aufzurichten, schließt daß Ventil 8 unter dem fehlenden Druck der Druckaufbaukammern 6 und sichert so das Druckniveau des Gasdruckkonverters d7. Der Druckeingang trägt die Bezeichnung 1 und der Druckausgang 2.In Fig. 2 the gas pressure reservoir has reached its maximum pressure level and the flexible internal gas pressure converter has reduced its volume under the high external pressure to such an extent that the two pressure build-up chambers 6 lie against one another in order to adjust the internal pressure level d7 to the external pressure level in connection with the valve 8 , begins the gas pressure converter to rise under the relaxation, closes the valve 8 under the missing pressure of the pressure build-up chambers 6 and thus secures the pressure level of the gas pressure converter d7. The pressure inlet is labeled 1 and the pressure outlet 2 .

Claims (1)

Der interne Gasdruckkonverter, für den ich Patentschutz beantrage, läßt sich aufgrund seiner flexiblen Hülle und seines eigenen Druckaufbausystems in prinzipiell alle Luftkessel und Gasdruckvorratsbehälter einsetzen, seine Kunstfaserhülle macht es überflüssig, ihn regelmäßig zu warten.
Da der interne Gasdruckkonverter grundsätzlich mit dem Medium, das unter Druck gesetzt werden soll, befüllt ist und er durch ein eigenes Druckaufbausystem verfügt, ist es nicht notwendig, ihn von außen zu befüllen oder seinen Druck zu regulieren.The internal gas pressure converter, for which I am applying for patent protection, can in principle be used in all air boilers and gas pressure reservoirs due to its flexible casing and its own pressure build-up system; its synthetic fiber casing makes it unnecessary to maintain it regularly.
Since the internal gas pressure converter is basically filled with the medium that is to be pressurized and it has its own pressure build-up system, it is not necessary to fill it from the outside or to regulate its pressure.
