KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Diese Erfindung bezieht sich auf die Vertheilung des Flüssigkeitsdruckes in einer einfach wirkenden Maschine mit in der Mitte angeordnetem Schieber, wie sie in den englischen Patenten Nr. 13769 vom Jahre 1884 und 1852 vom Jahre 1885 von Peter William Willans beschrieben sind. Solche Maschinen werden manchmal derart angeordnet, dafs die entweichende Flüssigkeit nicht unmittelbar aus dem Arbeitscylinder in den Auspuff gelangt, sondern zuerst aus dem Druckende des Cylinders in das andere, und dann beim folgenden Hub aus dem Cylinder in den Auspuff.This invention relates to the distribution of fluid pressure in a simple manner acting machine with a slide arranged in the middle, as in the English Patents No. 13769 dated 1884 and 1852 from 1885 by Peter William Willans. Such machines will be sometimes arranged in such a way that the escaping liquid does not come out immediately the working cylinder gets into the exhaust, but first out of the pressure end of the cylinder into the other, and then on the following stroke out of the cylinder into the exhaust.
Die Maschine mit Mittelschieber, von der ein Theil in Fig. 1 gezeigt ist, ist so angeordnet. Gerade bevor die Kolben das untere Ende ihres Hubes erreichen, geht der Schieber V1 über die Oeffnungen P1 und bringt dieselben mit P2 in Verbindung, wodurch die Druckflüssigkeit aus dem Arbeitsende des Cylinders. in das untere Ende desselben gelangen kann. Während des gröfsten Theiles des Aufwärtshubes geht die Flüssigkeit so ohne wesentliche Volumenänderung über, indem die Verbindung zwischen P1 und P2 gerade vor Schlufs der Aufwärtsbewegung unterbrochen wird. Unmittelbar nachher öffnet das Herabgehen des hohlen Kolbenschiebers Vs und F4 die Wege P3 und P4 und bringt so P2 und den unteren Theil des Cylinders X mit dem Raum Y in Verbindung, in welchen das Auspuffrohr mündet.The center slide machine, part of which is shown in Fig. 1, is so arranged. Just before the pistons reach the lower end of their stroke, the slide V 1 goes over the openings P 1 and brings them into connection with P 2 , whereby the pressure fluid from the working end of the cylinder. can get into the lower end of the same. During the largest part of the upward stroke, the liquid passes over without any significant change in volume, in that the connection between P 1 and P 2 is interrupted just before the end of the upward movement. Immediately afterwards, the descent of the hollow piston valve V s and F 4 opens the paths P 3 and P 4 and thus brings P 2 and the lower part of the cylinder X into communication with the space Y into which the exhaust pipe opens.
Man bemerkt nun, dafs die Schieber F3 und Vi im wesentlichen den Auspuff bewirken, dafs er aber stattfindet, wenn die Schieberreihe, von der sie einen Theil bilden, den Eintritt in das Arbeitsende des Cylinders freigiebt. Hierdurch wird der Umstand beseitigt, der bei Schiebern einfach wirkender Maschinen gewöhnlich vorhanden ist, nämlich der, dafs ihre Bewegung abwechselnd, den Eintritt und den Auspuff freigiebt und nicht beide zugleich, wodurch es schwierig gemacht wird, einen hinreichend freien Auspuff zu erzielen. Durch vorliegende Erfindung wird diese Schwierigkeit vermieden, indem man die Auslafsschieber theilt und dadurch die Auslafsöffnung vergröfsert. Hierdurch wird eine hinreichende Durchlafsöffnung erzielt, ohne die hohle Kolbenstange zu erweitern.If one now observed, that the slides 3 and F V i substantially effect the exhaust, but it DAF takes place when the slide set, of which they form a part, freigiebt entry into the working end of the cylinder. This eliminates the fact that is usually present in single-acting machines, namely that their movement alternately clears the inlet and the exhaust, and not both at the same time, which makes it difficult to obtain a sufficiently clear exhaust. The present invention avoids this difficulty by dividing the outlet slides and thereby enlarging the outlet opening. In this way, a sufficient through-flow opening is achieved without widening the hollow piston rod.
