Dampfpumpe ohne Schieber und Ventile, deren Kolben behufs Steuerung um die HauptaxeSteam pump without slide and valves, their pistons for control around the main axis

oscilliren.oscillate.

Patentirt im Deutschen Reiche vom 27.. Juli 1877 ab.Patented in the German Empire from July 27th, 1877.

Bei der vorliegenden Dampfpumpe wird die Dampfvertheilung durch den eigenthümlich construirten Dampfkolben bewirkt und die Ventile der doppeltwirkenden Pumpe werden durch den Pumpenkolben ersetzt.In the case of the present steam pump, the steam distribution is constructed by the peculiarly designed one Steam piston effects and the valves of the double-acting pump are replaced by the pump piston.

Dampf- und Pumpencylinder sind hintereinander auf einem gemeinschaftlichen Bett gelagert und beide Kolben sitzen auf einer durchgehenden Kolbenstange, welche aufser ihrer hin- und hergehenden Bewegung noch eine Oscillation um ihre Axe erhält, wodurch die Steuerung bewirkt wird.Steam and pump cylinders are stored one behind the other on a shared bed and both pistons sit on a continuous piston rod, which, in addition to their back and forth moving motion still receives an oscillation around its axis, whereby the control is effected.

Fig. ι der beiliegenden Zeichnung stellt eine Längsansicht, Fig. 2 einen Horizontalschnitt der Maschine dar, die übrigen Fig. 3 bis 19 sind Details, deren Bedeutung im Laufe der Beschreibung erklärt werden wird.Fig. Ι of the accompanying drawings shows a longitudinal view, FIG. 2 shows a horizontal section of the Machine, the remaining FIGS. 3 to 19 are details, the meaning of which in the course of the description will be explained.

Der Dampfcylinder A und der Pumpencylinder B sind einander genau gleich gestaltet, und besitzen aufser den vier zur Befestigung auf dem Bett dienenden Füfsen keine weiteren äufseren Ansätze, als die Ein- und Ausströmimgsstutzen a und b. Die Kolben dieser Cylinder sind jedoch verschieden, die gemeinschaftliche Hin- und Herbewegung der Kolbenstange F wird durch ein Schwungrad C, welches mittelst Kurbel D und Peuelstange E betrieben wird, regulirt. Die Oscillation der Kolbenstange erfolgt durch einen zwischen beiden Cylindern auf derselben befestigten Dorn c, der mit seinem unteren Ende in eine Führungsnuth d greift, s. Fig. 17 bis 19. Die schwingende Bewegung des Dorns wird durch ein um den Zapfen e drehbares Schiffchen / unterstützt; letzteres wird durch zwei Federn g, welche sich gegen zwei Stifte h des Schiffchens/legen, gezwungen, sich nach rechts zu drehen (im Sinne des Zeigers der Uhr). Kommt demnach der Dorn c aus der Position 1, Fig. 18, in die Position 2, welche dem Ende des Kolbenhubes entspricht, so schnellt das Schiffchen / in die punktirt gezeichnete Lage, und der Dorn c kann um die Spitze /, herum in den nach rechts führenden Kanal gelangen. Infolge dieser Bewegungen oscillirt die Kolbenstange F um einen Winkel a, während jeden Hubes, wodurch, wie schon oben angedeutet, die Dampfvertheilung bewirkt und das Spiel gewöhnlicher Pumpenventile der doppeltwirkenden Pumpe ersetzt wird.The steam cylinder A and the pump cylinder B are designed in exactly the same way, and apart from the four feet used to fasten them to the bed, they have no further external attachments than the inlet and outlet ports a and b. The pistons of these cylinders, however, are different; the mutual reciprocation of the piston rod F is regulated by a flywheel C, which is operated by means of crank D and connecting rod E. The Oscillation of the piston rod is effected by a fixed between the two cylinders on the same mandrel c which engages with its lower end in a Führungsnuth d, s. Figs. 17 to 19. The oscillating movement of the mandrel is a rotatable about the pin e shuttle / supports; The latter is forced to turn to the right by two springs g, which lie against two pins h of the shuttle /, (in the sense of the pointer of the clock). If the mandrel c comes from position 1, FIG. 18, into position 2, which corresponds to the end of the piston stroke, the shuttle / snaps into the position shown in dotted lines, and the mandrel c can go around the tip / into the get to the right leading canal. As a result of these movements, the piston rod F oscillates through an angle a, during each stroke, which, as already indicated above, causes the Dampfvertheilung and replaces the ordinary game pump valves of the double-acting pump.

Zu diesem Zwecke besitzt der Dampfkolben G an seiner Mantelfläche kleine Kanäle, welche der Drehbewegung entsprechend in Richtung und Länge so geformt sind, dafs sie die richtige Dampfein- und Ausströmung bewirken. Der Kolben schliefst daher auf seiner ganzen Länge dampfdicht an die Cylinderwandung an. Er besteht aus einer cylindrischen Hülse G\ welche zickzackförmig aufgeschnitten ist, und durch die an jedem Kopfende eingeschobenen kegelförmigen Böden H1 und H1, von denen ersterer auf der Kolbenstange mittelst Konus i befestigt ist, letzterer durch eine durch die Stopfbüchse reichende Schraubenbüchse k ersterer genähert wird, so ausgedehnt werden kann, dafs weder eine' zu grofse Reibung, noch ein merklicher Dampfverlust stattfinden kann.For this purpose, the steam piston G has small channels on its outer surface, which are shaped according to the rotational movement in direction and length so that they cause the correct steam inflow and outflow. The piston therefore adjoins the cylinder wall in a vapor-tight manner over its entire length. It consists of a cylindrical sleeve G, which is cut open in a zigzag shape, and through the conical bottoms H 1 and H 1 inserted at each head end, the former being fastened to the piston rod by means of a cone i , the latter through a screw sleeve k the former extending through the stuffing box can be extended so that neither too great a friction nor a noticeable loss of steam can take place.

Die Büchse k ist mit dem Konus H1 fest verbunden und besitzt am Ende ein Muttergewinde mittelst dessen sie auf das in die Kolbenstange F geschnittene Gewinde geschraubt ist; aufserhalb ist sie mit einem gezahnten Kranz versehen, welche zum Ansetzen eines Schraubenschlüssels dient, um ein Drehen der Büchse zu ermöglichen. Der Konus H greift mittelst eines cylindrischen Ansatzes etwas über den festen Konus H1 , wodurch er noch geführt wird; der Raum zwischen den Konus und der Kolbenhülse G1 ist mit einer nachgiebigen Packung / gefüllt. Der durch den Einströmungsstuzen a zum Cylinder gelangende Dampf wird durch die Kanäle Hi1 und m, vor oder hinter den Kolben geleitet, und durch die Kanäle «, und nä abgeführt. Die einzelnen Kolbenstellungen sind in den Fig. 3 bis 8 dargestellt. Die Fig. 3 und 4 zeigen den Kolben in seiner Mittelstellung, wenn er sich von rechts nach links bewegt; dem entspricht die in Fig. 19 gezeichnete Stellung des Führungsdorns c. Die Dampfeinströmung ist durch Pfeile angedeutet und bedarf keiner weiteren Erläuterung.The bush k is firmly connected to the cone H 1 and has a female thread at the end by means of which it is screwed onto the thread cut into the piston rod F; outside it is provided with a toothed ring, which is used to attach a wrench to enable the bushing to be turned. The cone H grips somewhat over the solid cone H 1 by means of a cylindrical attachment, whereby it is still guided; the space between the cone and the piston sleeve G 1 is filled with a flexible packing /. The passing through the Einströmungsstuzen to a cylinder steam is passed through the channels Hi and 1 m, in front or behind the piston, and discharged through the channels ä "and n. The individual piston positions are shown in FIGS. Figures 3 and 4 show the piston in its central position as it moves from right to left; the position of the guide pin c shown in FIG. 19 corresponds to this. The inflow of steam is indicated by arrows and does not require any further explanation.

Die Länge des auf der Mantelfläche des Kolbens mündenden Kanals M1 bedingt natürlich die Expansion. In den Fig. 5 und 6 hat der Kolben das Ende des Hubes erreicht, Eämmtliche Kanäle sind geschlossen, wie aus The length of the channel M 1 opening onto the lateral surface of the piston naturally causes the expansion. In FIGS. 5 and 6 the piston has reached the end of its stroke, all of the channels are closed, as shown in FIG

dem Querschnitt Fig. 6 ersichtlich. Die Fig. 7, 8 und 17 endlich zeigen den Kolben wiederum in seiner Mittelstellung, wenn .er sich von links nach rechts bewegt.the cross section of FIG. 6 can be seen. Finally, FIGS. 7, 8 and 17 show the piston again in its middle position when it moves from left to right.

Die Construction des Pumpenkolbens kann in zweierlei Weise ausgeführt werden; die Fig. 9 bis 12 zeigen die erste, auch in dem Horizontalschnitt Fig. 2 gezeichnete Modification; die Fig. 13 bis 14 eine andere Construction. Bei ersterer besteht der Pumpenkolben K aus zwei vollen Scheiben 0, welche ungefähr um die Länge des Hubes von einander entfernt und durch zwei Stege / und einen Kern q mit einander verbunden sind. Um die Schieber sind Ramsbottom'sche Dichtungsringe χ gelegt, welche über die Stege hinweg mit einander verbunden sind, und so diese und die Scheiben wasserdicht gegen die Cylinderwand dichten. Die Scheiben ο sind wechselseitig durchbrochen, so dafs dadurch Kanäle r gebildet werden, wovon der eine vor und der andere hinter dem Kolben ausmündet. Wie aus Fig. 2 ersichtlich, ist der Raum rechts dem Kolben Säugraum, links desselben Druckraum. Am Ende des Hubes sind die Kanäle, wie Fig. 12 zeigt, abgesperrt und bei der Bewegungsumkehrung der Kolbenstange wechseln die Kanäle r und der Saugraum von vorhin wird Druckraum und umgekehrt. Bei der in den Fig. 13 bis 16 gezeichneten Modification ist der Kolben mit halben Scheiben / an seinen Enden versehen, wodurch die Kanäle fortfallen und der Kolben in seiner Projection (Fig. 15) eine Z-Form erhält.The construction of the pump piston can be carried out in two ways; 9 to 12 show the first modification, also drawn in the horizontal section of FIG. 2; FIGS. 13 to 14 show a different construction. In the former, the pump piston K consists of two full disks 0, which are separated from one another by approximately the length of the stroke and are connected to one another by two webs / and a core q . Ramsbottom's sealing rings χ are placed around the slides, which are connected to one another via the webs and thus seal these and the disks in a watertight manner against the cylinder wall. The disks ο are alternately perforated so that channels r are formed, one of which opens out in front of and the other behind the piston. As can be seen from FIG. 2, the space on the right is the suction space of the piston and the same pressure space on the left. At the end of the stroke, the channels are blocked, as shown in FIG. 12, and when the movement of the piston rod is reversed, the channels r change and the suction chamber from before becomes the pressure chamber and vice versa. In the modification shown in FIGS. 13 to 16, the piston is provided with half disks / at its ends, as a result of which the channels are omitted and the projection (FIG. 15) gives the piston a Z-shape.

Da die Kolbenstange oscillirt, so ist das Querhaupt ν nicht festgekeilt, sondern durch zwei Ringe w gehalten und wird erstere noch durch den Führungsbock M geführt.Since the piston rod oscillates, the crosshead ν is not wedged, but held by two rings w and the former is still guided by the guide block M.

Die Gesammtwirkung der Construction dürfte aus. dem Gesagten hinreichend verständlich sein und mag nur noch erwähnt werden, dafs die Anwendung der oscillirenden Kolbenbewegung sich auch auf einfache Betriebsmaschinen ausdehnen läfst.The overall effect of the construction should be off. be sufficiently understandable what is said and it may only be mentioned that this is the application of the oscillating piston movement can also be extended to simple operating machines.
