Das Werkgehäuse A, Fig. 2, bildet in seiner unteren Fortsetzung den runden Flantsch JB. Zwischen diesem Flantsch B und dem Gegenflantsch C ist die gewellte Plattenfeder D, welche den bei Έ eintretenden Druck aufnimmt, mittelst sechs Schrauben abgedichtet. Die durch den Druck verursachte Bewegung der Feder wird durch einen Mechanismus vergröfsert und auf einen Zeiger übertragen, wie folgt: Von der Feder D führt eine Verbindungsstange, in welcher zur besseren Nachgiebigkeit ein Kugelgelenk F eingeschaltet ist, nach der kleinen Kurbel G. Diese ist mit dem in dem Bocke H gelagerten Radsegment J fest verbunden. Das Radsegment J greift in das im Bocke K gelagerte Trieb L, Fig. 3. Auf der Triebaxe ist die Kurbel M befestigt, an dieser wieder der Zeiger N, und zwar so, dafs sich derselbe in den in ihm befindlichen Schlitze, Fig. 1, der Länge nach verschieben kann.The movement housing A, Fig. 2, forms the round flange JB in its lower continuation. Between this flange B and the counter flange C , the corrugated diaphragm D, which absorbs the pressure occurring at Έ, is sealed by means of six screws. The movement of the spring caused by the pressure is enlarged by a mechanism and transferred to a pointer as follows: A connecting rod leads from the spring D , in which a ball joint F is inserted for better flexibility, after the small crank G. This is with firmly connected to the wheel segment J mounted in the bracket H. The wheel segment J engages in the drive L mounted in the bracket K , Fig. 3. The crank M is fastened to the drive axle, to this again the pointer N, in such a way that it is in the slots in it, Fig. 1 that can move lengthways.
Der Zeiger führt sich ferner mit dem Stift O in dem spiralförmigen Schlitz des Ziiferblattes P, wodurch derselbe genöthigt ist, eine dem Schlitze gleich spiralförmige Umdrehung anzunehmen. Die Glasscheibe Q, die durch den Ring R gehalten wird, stellt den inneren Verschlufs her.The pointer also guides itself with the pin O in the spiral-shaped slot of the dial P, whereby the pointer is forced to assume a spiral-shaped rotation equal to the slot. The glass pane Q, which is held by the ring R , forms the inner lock.
Der Vortheil dieses Manometers gegenüber den anderen besteht hauptsächlich darin:The main advantage of this manometer over the others is:
Es wird der Druck mit gröfserer Genauigkeit markirt,. da die einzelnen Atmosphären infolge der spiralförmigen Anordnung eine solche Länge erhalten, dafs sie bequem in hundert Theile getheilt werden können, mithin der Druck nach Hundertstel-Atmosphären bestimmt werden kann, was bei den jetzigen Manometern der kurzen Theilungen wegen nicht möglich ist.The pressure is marked with greater accuracy. because the individual atmospheres as a result The spiral arrangement is given such a length that it can easily be divided into a hundred parts can be divided, so the pressure can be determined according to hundredths of an atmosphere, which is not possible with the present pressure gauges because of the short divisions.
