KLASSE 59: Pumpen.CLASS 59: Pumps.

Die Mischdüse α ist mit einem beweglichen Seitentheil b versehen, welcher in bekannter Weise vor dem Ansaugen durch den von c einströmenden Dampf angehoben wird und diesem den freien Austritt durch den Schlabberstutzen d gestattet. Zufolge des ungehinderten Dampfaustrittes findet das Ansaugen des Wassers bei f statt. Sobald das Wasser angesogen ist und sich bei g mit dem Dampfe vermischt hat, entsteht an dieser Stelle ein Vacuum, durch welches der bewegliche Düsentheil b angesogen und die Mischdüse geschlossen gehalten wird.The mixing nozzle α is provided with a movable side part b , which is raised in a known manner by the steam flowing in from c before it is sucked in and allows it to exit freely through the slack nozzle d. As a result of the unimpeded escape of steam, the water is sucked in at f . As soon as the water has been sucked in and has mixed with the steam at g , a vacuum is created at this point through which the movable nozzle part b is sucked in and the mixing nozzle is kept closed.

Die Trennungsflä'che χ χ χ' χ' zwischen dem festen und dem beweglichen Theile der Mischdüse ist bei der vorliegenden Construction verhä'ltnifsmäfsig grofs gehalten und mit Aussparungen yy versehen. Diese Aussparungen stehen bei geschlossener Mischdüse durch die Kanäle ^ % nur mit demjenigen Theile des Düseninnern in Verbindung, in welchem ein hohes Vacuum herrscht. Die Aussparungenyy bewirken sonach auf ihrer ganzen Fläche ein energisches Zuhalten des beweglichen Mischdüsentheiles b. The area of separation χ χ χ 'χ' between the fixed and the movable part of the mixing nozzle is kept relatively large in the present construction and provided with recesses yy . These recesses are closed mixing nozzle through the channels ^% only with that part of the nozzle interior, in conjunction, in which a high vacuum prevails. The recesses yy therefore cause the movable mixing nozzle part b to be energetically closed over their entire surface.

Während bei älteren Mischdüsen der dargestellten Art der Schlufs nur durch das Ansaugen auf den Querschnitt t u ν w der konischen Ausbohrung bewirkt wurde, und hier naturgemäfs nur durch das an jeder Stelle der Bohrung herrschende — von tu nach vw allmälig abnehmende Vacuum — besitzt die dargestellte Düse eine vermehrte zuhaltende Kraft, welche abhängig ist von der Flächenausdehnung der Aussparungen yy und dem constant hohen Vacuum bei ζ %. While with older mixing nozzles of the type shown, the closure was only caused by the suction on the cross-section tu ν w of the conical bore, and here naturally only by the vacuum that prevails at every point of the bore - gradually decreasing from tu to vw - the nozzle shown has an increased locking force, which is dependent on the area of the recesses yy and the constant high vacuum at ζ%.

In der Zeichnung ist der bewegliche Düsentheil b als eine um die Achse ο ο pendelnde Scharnierklappe ausgebildet, welche seitlich in den Haupt-Düsenkörper α eingeschoben und durch einen Stift s am Herausfallen gehindert wird. Die Scharniermutter ο ο schneidet die Längsachse A B der Düse. Der cylindrische Theil x' x' x'1 x" des beweglichen Düsenstückes bildet das Scharnier; die konische Bohrung der Düse führt durch diesen Scharniercylinder hindurch und wird von ihm allseitig umschlossen. Diese gezeichnete Anordnung der Scharnierklappe hat den Vortheil, dafs die Klappe wenig Raum erfordert und dabei sicher innerhalb des Haupt-Düsenstückes α gelagert ist.In the drawing, the movable nozzle part b is designed as a hinge flap swinging around the axis ο ο, which is pushed laterally into the main nozzle body α and is prevented from falling out by a pin s. The hinge nut ο ο intersects the longitudinal axis AB of the nozzle. The cylindrical part x 'x' x ' 1 x "of the movable nozzle piece forms the hinge; the conical bore of the nozzle leads through this hinge cylinder and is enclosed on all sides by it. This illustrated arrangement of the hinged flap has the advantage that the flap has little space requires and is safely stored within the main nozzle piece α.
