HEINRICH HIRZEL in LEIPZIG. Druckregulator für comprimirtes Gas.HEINRICH HIRZEL in LEIPZIG. Compressed gas pressure regulator.

Patentirt im Deutschen Reiche vom II. September 1877 ab.Patented in the German Empire on September 2nd, 1877.

Zweck dieses Regulators ist, Leuchtgas, welches unter hohem Drucke, z. B. von acht Atmosphären, in einen transportablen Kessel eingefüllt worden ist, zur directen Verwendung geeignet zu machen. Schaltet man nämlich zwischen den, das comprimirte Leuchtgas enthaltenden Kessel und die von dem Kessel aus zu den Brennern geführte Rohrleitung einen solchen Drückregulator ein, so wird durch letzteren der hohe Druck, mit dem das Gas aus dem Kessel zu entweichen¹ strebt auf das für die Beleuchtung günstigste Verhältnifs ermäfsigt und während des Brennens constant auf diesem günstigsten Verhältnisse erhalten, auch wenn allmälig der Gasdruck im Kessel infolge des stattfindenden Gasverbrauches abnimmt.The purpose of this regulator is, luminous gas, which under high pressure, z. B. of eight atmospheres, has been filled in a portable boiler, to make suitable for direct use. If one switches namely between which comprimirte phosphor containing gas boiler and the guided from the boiler to the burners pipe such a push regulator a so by the latter, the high pressure at which the gas from the vessel to escape ¹ aims at the Illumination of the most favorable proportions is reduced and is kept constant during the burning at this most favorable proportions, even if the gas pressure in the boiler gradually decreases as a result of the gas consumption which takes place.

Die Zeichnungen auf Blatt I und II geben ein genaues Bild der Form und Construction meines neuen Druckregulators.The drawings on sheets I and II give a precise picture of the form and construction of my new pressure regulator.

Construction. A ist das gufseiserne Gehäuse des Regulators, dessen beide Endflächen mit den Membranen MM als Druckflächen lose überspannt sind, derart, dafs dadurch der innere Raum des Gehäuses vollkommen gasdicht verschlossen ist. Durch den Stutzen V gelangt das in einem Kessel befindliche comprimirte Leuchtgas aus dem Kessel in das Gehäuse, während es durch den Stutzen N mit demjenigen Drucke nach den Brennern fortgeleitet wird, der für die Bildung einer schönen, hellleuchtenden, ruhigen Flamme der günstigste ist. Im Eingangsstutzen V sitzt das den Gasdruck regulirende Kolbenventil 0, welches als Dichtungsfläche eine kleine Korkplatte trägt, wodurch in einfachster Weise ein absolut gasdichter und dauerhafter Verschlufs hergestellt ist, der weder vom Gas angegriffen, noch durch zutretende Staubtheilchen in seiner Function gestört wird und leicht und überall erneuert werden kann. Das Ventil ο steht durch ein an dem beweglichen Bolzen b sitzendes Excenter e und durch den an demselben Bolzen befestigten Doppelhebel d, die Zugstangen // und die Hebel h h mit den Membranen MM so in Verbindung, dafs jede Bewegung der Membranen durch die genannten Theile auf das Ventil übertragen wird. Die Theile// sind am' Gehäuse befestigt und tragen je an dem einen Ende die Drehungspunkte, am anderen Ende die Führungen der Hebel h h. r ist eine linksgewundene Spiralfeder, welche auf Torsion und bei dem geringen Hube des Ventils nur auf ein sehr geringes Maafs ihrer Leistungsfähigkeit beansprucht wird. Mit ihren Enden ist diese Feder am Bolzen b und an der durch die Gehäusewand gehenden, von aufsen drehbaren, mit Gegenmutter versehenen Schraube ί befestigt. Diese Feder dient zum Justiren des Regulators und hält im Ruhestand das Ventil oifen. Die schon erwähnten Membranen MM bestehen aus einem neuen, eigenthümlichen, vollständig gasdichten Material, welches ich anfertige, indem ich zwischen zwei Lagen Shirting oder anderem ziemlich feinen Stoff, eine Lage sogenanntes Guttaperchapapier lege, das Ganze zwischen heifsen Walzen presse und . auf beiden Seiten dünn mit einem nicht springenden Lack überziehe. Die Membranen M M werden gegen äufsere Beschädigung durch die darüber geschraubten gufseisernen Deckel g g geschützt. In diese Deckel sind die Löcher q q eingebohrt, damit beim Spannen der Membranen die verdrängte Luft entweichen, oder im anderen Falle in den Raum zwischen Deckel und Membran eindringen kann. Bei Benutzung des Druckregulators zur Eisenbahnwagen-Beleuchtung wird der Regulator mit der angegossenen Platte F am Untergestell des zu beleuchtenden Wagens angeschraubt und mit dem Kessel und den Flammen durch Rohrleitung verbunden.Construction. A is the cast iron housing of the regulator, the two end faces of which are loosely spanned by the membranes MM as pressure surfaces, in such a way that the inner space of the housing is completely sealed in a gas-tight manner. The compressed luminous gas in a boiler passes through the connection V into the housing, while it is passed through the connection N to the burners with that pressure which is the most favorable for the formation of a beautiful, bright, calm flame. The piston valve 0, which regulates the gas pressure and has a small cork plate as a sealing surface, is located in the inlet connection V , whereby an absolutely gas-tight and permanent closure is produced in the simplest way, which is neither attacked by the gas nor disturbed in its function by dust particles and is light and easy can be renewed anywhere. The valve ο stands by on the movable bolt b seated eccentric e and d by the attached thereto bolt double lever, the tie rods // and the lever hh with the membranes MM so connected, that any movement of the diaphragms by said part to the valve is transmitted. The parts are fastened to the housing and each bear the pivot points at one end and the guides for the levers at the other end . r is a left-hand spiral spring which is subjected to torsion and, given the small stroke of the valve, only a very small amount of its efficiency. With its ends, this spring is fastened to the bolt b and to the screw ί which goes through the housing wall and rotates from the outside and is provided with a lock nut. This spring is used to adjust the regulator and keeps the valve open when it is not in use. The MM membranes already mentioned consist of a new, peculiar, completely gas-tight material, which I make by placing a layer of so-called gutta-percha paper between two layers of shirting or other fairly fine material, pressing the whole thing between hot rollers and. thinly coat both sides with a non-cracking varnish. The MM membranes are protected against external damage by the cast-iron covers gg screwed over them. The holes qq are drilled into these covers so that the displaced air can escape when the membranes are tensioned or, in other cases, can penetrate into the space between the cover and the membrane. When using the pressure regulator for railway car lighting, the regulator with the cast plate F is screwed to the underframe of the car to be illuminated and connected to the boiler and the flames by piping.

Wirkungsart. Wird durch Oeffnen der Brennerhähne, bezw. durch Anzünden der mit Gas zu versorgenden Flammen, der Apparat in Thätigkeit gesetzt, so strömt das comprimirte Gas, nachdem es den Ventilverschlufs passirt hat, durch drei seitliche Oeffnungen 0 in den freien Raum des Regulatorgehäuses A ein und übt in diesem einen Druck aus auf die Membranen MM. Ist dieser Druck stark genug, um den Gegendruck der Feder r zu überwinden, so werden die Membranen nach aufsen aufgetrieben und ziehen die Hebel h h nach sich. Dieser Bewegung folgt das ganze Hebelsystem, so dafs schliefslich das Excenter e das Ventil gegen seinen Sitz bewegt, wodurch der Gaszuflufs ganz oder theilweise unterbrochen wird. Sinkt dann, infolge des Gasabganges nach den Brennern hin, die Spannung im Gehäuse wieder etwas, so überwindet der Druck des vom Kessel aus wirkenden comprimirten Gases auf das Ventil und die in demselben Sinne wirkende Kraft der Feder,Mode of action. Is by opening the burner taps, respectively. by lighting the flames to be supplied with gas, the apparatus is put into action, the compressed gas, after having passed the valve closure, flows through three lateral openings 0 into the free space of the regulator housing A and exerts a pressure on the latter Diaphragms MM. If this pressure is strong enough to overcome the counter pressure of the spring r , the diaphragms are forced outwards and pull the levers hh towards them. This movement is followed by the whole system of levers, so that finally the eccentric e moves the valve against its seat, whereby the gas supply is wholly or partially interrupted. If, as a result of the gas outlet towards the burners, the tension in the housing falls again somewhat, the pressure of the compressed gas acting from the boiler overcomes the valve and the force of the spring acting in the same sense.

the counter-pressure of the gas still "located" inside the housing on the membranes, as a result, the valve opens again to a corresponding extent, allowing new gas into the Enter the housing until the play repeats itself with increasing pressure in the housing,

By means of the spring r, which can be tightened more or less, one is able to adjust the regulator so that it delivers the gas to the burner with the most favorable pressure for the formation of good flames. Since, however, depending on the quality of the gas and the size and type of the burner, the gas pressure most suitable for obtaining a good flame is somewhat different, it is not possible to adjust the regulator from the outset so that it always works produces the most suitable gas pressure for the burners. Likewise, after any repairs or cleaning, it would be difficult for the less experienced to readjust the regulator so that it works again without further ado with the same pressure as before. It is therefore of great value to be able to adjust the pressure regulator from the outside without causing any disturbance. This adjustment from the outside is very easy with the new pressure regulator by means of the screw ί. If the .Druck under which the gas from the regulator to the burners flows too low, the flames burn a bit too small and there is now only necessary the screw mentioned s turn around so long left until the flames the desired Effect give, and then tighten the lock nut. Turning the screw ί clockwise, on the other hand, reduces the burner pressure.

Advantages and peculiarities. The new pressure regulator is particularly distinguished by virtues and peculiarities emphasized below over those known up to now Pressure regulators for compressed gas, namely that of Julius Pintsch in Berlin:

i. It is so solidly constructed that repairs can be made will only seldom prove necessary in the same. Especially durable and the membranes are insensitive to temperature and weather. Likewise offers also the closing surface of the valve, which is neither caused by the gas nor by dust particles and the like undergoes a change, the guarantee of a permanently absolutely tight seal, j

2. It is so simply arranged that the treatment it can be learned very easily; it is also easy to open and clean, or repair it without having to unscrew it from the car while the Pintsch regulator can only be opened after it has been unscrewed from the trolley has been.

3. He is insensitive to all jolts and vibrations of the rolling along with him Wagen and owes this extremely important advantage especially to the circumstance that he has two opposing membranes which are vertical and in the longitudinal direction of the The car, so that it is not exposed to violent knocks and vibrations. Of the On the other hand, the Pintsch regulator has only one membrane, which is horizontal and as a result is constantly under the influence of all shocks and tremors.

4. It functions more precisely than the previously known regulators for compressed gas; the flames therefore burn evenly brightly until the gas boiler is completely emptied. B. the one membrane of the Pintsch regulator. But the larger the surface area which regulates the gas pressure, the more even the pressure regulation. On the other hand, the aforementioned advantage is brought about by the spring r and its adjusting device.

5. It works with ease for everyone special Make the case exactly right from the outside, even during operation.

P a ten τ claims:

In addition to the entire construction of the new pressure regulator, which is a special one that has not yet been implemented, the inventor claims the patent in particular:
ι. for the use of two membranes, through which the apparatus receives a high degree of perfection in terms of its efficiency;

2. for the exact adjustability of the regulator to be effected from the outside by means of the screw ί and spring r, whereby the same is extremely convenient for practical use.
