KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei bekannten Dampfmessern mit einem an einer Feder hängenden Hohlkörper, der sich in Abhängigkeit von der Druckdifferenz zu beiden Seiten einer Drosselstelle in der Dampfleitung aus einem Quecksilberdruckraum mehr oder weniger mit Quecksilber füllt, macht die Verbindung zwischen Quecksilberdruckraum und Hohlkörper Schwierigkeiten. Diese Schwierigkeiten lassen sich vermeiden, wenn manIn known steam knives with a hollow body hanging on a spring, which depending on the pressure difference on both sides of a throttle point in the steam line fills a mercury pressure chamber more or less with mercury, she does Connection between the mercury pressure chamber and the hollow body Difficulties. These difficulties can be avoided if one
ίο den an der Feder hängenden Hohlkörper, der sich bei sich ändernder Druckdifferenz zu beiden Seiten der Drosselstelle in der Leitung mehr oder weniger mit Quecksilber füllen soll, in dem Quecksilberdruckraum selbst anordnetίο the hollow body hanging on the spring, the when the pressure difference changes on both sides of the throttle point in the line should fill more or less with mercury, in the mercury pressure chamber itself arranges
und ihn mit seiner unteren freien Öffnung unmittelbar in das Qnecksilber des Druckraumes eintauchen läßt. Außerdem werden durch eine solche Anordnung des federnd aufgehängten Hohlkörpers im Quecksilberdruckraum die Abmessungen des Apparates verringert, und die Hin- und Herbewegungen des Quecksilbers aus dem Quecksilberdruckraum nach dem Innenraum des Hohlkörpers und zurück verursachen bei Dampfstößen in der Leitung, wie sie bei Maschinenbetrieb eintreten, geringere Schwankungen in der Anzeige, da bei Anordnung des Hohlkörpers in dem Quecksilberdruckraum selbst das Gewicht des Quecksilbers im Hohlkörper nicht mehr an der Feder hängt, sondern vom Druck in dem den Hohlkörper aufnehmenden Raum getragen wird.and lets it immerse itself with its lower free opening directly into the silver of the pressure chamber. Also be by such an arrangement of the resiliently suspended hollow body in the mercury pressure chamber reduced the dimensions of the apparatus, and the reciprocation of the mercury from the mercury pressure space after the interior of the hollow body and back cause bursts of steam in the Line, as they occur during machine operation, smaller fluctuations in the display, since when the hollow body is arranged in the mercury pressure space itself, the weight of the mercury in the hollow body is no longer depends on the spring, but is borne by the pressure in the space receiving the hollow body.
Der neue Dampfmesser ist auf der Zeichnung in zwei Ausführungsformen wesentlich schematisch dargestellt.The new steam meter is essential on the drawing in two embodiments shown schematically.
In dem Druckgefäß b, Fig. 1 und 2, ist der Hohlkolben α unter Federbelasturig d untergebracht. Von der Drosselstelle in der Leitung gehen z. B. mit Wasser gefüllte Rohre in das Gefäß b und unter die Glocke a, deren Unter-Öffnung durch Quecksilber vom Raum in 5 abgesperrt ist. Kommt der Überdruck aus der Richtung des Pfeils, so senkt sich die Glocke, während das Quecksilber in ihr steigt. Dadurch wird die Oberfläche desselben in der Glocke α und damit die nutzbare Druckfläche sowie der Ausschlag oder die Anzeige des mit α verbundenen Hebels bei gleichmäßig steigender Belastung kleiner (Fig. 1).In the pressure vessel b, Fig. 1 and 2, the hollow piston α is housed under spring elastic d. From the throttle point in the line go z. B. Pipes filled with water into the vessel b and under the bell a, the lower opening of which is blocked from the space in 5 by mercury. If the overpressure comes from the direction of the arrow, the bell lowers while the mercury rises in it. As a result, the surface of the same in the bell α and thus the usable pressure area as well as the deflection or the display of the lever connected to α becomes smaller with an evenly increasing load (Fig. 1).
■ Fig. 2 zeigt eine andere Form von α und b, die sich zu gleichem Zweck ergänzen.■ Fig. 2 shows another form of α and b, which complement each other for the same purpose.
