Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf solche Maschinen, bei denen die hin und her gehende Bewegung der Kolben mittels Kurvenführungen, auf die die Kolben einwirken, in eine Drehbewegung der Maschinenwelle umgesetzt wird, und bezweckt die Schaffung einer Dampfmaschine mit mehrfacher Expansion, bei der die an sich bekannten ringförmigen Kolben verwendet werden.The invention relates to such machines in which the reciprocating Movement of the pistons by means of cam guides on which the pistons act in a Rotary movement of the machine shaft is implemented, and the aim is to create a steam engine with multiple expansion, in which the per se known annular pistons are used.

Die Erfindung besteht darin, daß die sich gemeinsam verschiebenden Kolben derart untereinander verbunden sind, daß auf dem die Fassungsräume der Zylinder nach innen begrenzenden Rohr eine Führung entsteht.The invention consists in the fact that the pistons, which move together, are in such a way one below the other are connected that on the bounding the capacity of the cylinder inwardly Pipe creates a guide.

Auf der Zeichnung veranschaulicht die Figur teils im Schnitt, teils in Ansicht eine Ausführungsform einer Dampfmaschine mit zweifacher Expansion.In the drawing, the figure illustrates, partly in section, partly in view, an embodiment a steam engine with double expansion.

Wie aus dieser Figur zu ersehen, sind zwei Zylinder 1 für Hoch- und Niederdruck angeordnet, die auf dem Maschinenrahmen befestigt sind und eine ringförmige Form aufweisen, die nach außen hin durch eine zylindrische Wand von geeignetem Durchmesser und nach innen hin durch ein Rohr 2 begrenzt wird, in welch letzterem die Maschinenwelle 3 angeordnet ist. In dem so gebildeten ringförmigen Raum 4 gleitet ein ebenfalls ringförmiger Kolben 5, während in dem Raum 41 ein anderer Kolben 51 angeordnet ist, der mit dem ersteren Kolben durch die Muffe 6 in Verbindung steht, die zwischen dem Rohr 2 und der inneren Wand 71 mit Führung gleitet und sozusagen einen Gleitschuh für die gemeinsame Führung der beiden Kolben darstellt.As can be seen from this figure, two cylinders 1 for high and low pressure are arranged, which are mounted on the machine frame and have an annular shape delimited on the outside by a cylindrical wall of suitable diameter and on the inside by a pipe 2 becomes, in which the latter the machine shaft 3 is arranged. In the annular space 4 thus formed, a likewise annular piston 5 slides, while in the space 4 1 another piston 5 1 is arranged, which is in communication with the former piston through the sleeve 6, which is between the tube 2 and the inner wall 7 1 slides with a guide and, so to speak, represents a sliding shoe for the common guidance of the two pistons.

Der Kolben 5 ist mittels Stangen 61 durch die Wand 7 mit einem ringförmigen Kranz 8 verbunden. Dieser Kranz trägt Rollen 9, die auf die Kurvenführung wirken, welch letztere bei dieser Ausführungsform von einer Nut gebildet wird, die in der äußeren Wand einer auf der Maschinenwelle 3 befestigten zylindrischen Muffe 11 vorgesehen ist.The piston 5 is connected to an annular ring 8 by means of rods 6 1 through the wall 7. This ring carries rollers 9 which act on the cam guide, which in this embodiment is formed by a groove which is provided in the outer wall of a cylindrical sleeve 11 fastened on the machine shaft 3.

Der Kranz 8 wird mittels der parallel zu der Treibwelle liegenden Aussparungen oder Schlitze 12 geführt, die in einer mit den Zylindern fest verbundenen Muffe vorgesehen sind, und in welche an dem Kranz drehbar gelagerte Rollen 13 eingreifen.The ring 8 is made by means of the recesses or slots lying parallel to the drive shaft 12 out, which are provided in a sleeve firmly connected to the cylinders, and in which engage rollers 13 rotatably mounted on the rim.

Zum Ausgleich der Maschine ist es vorteilhaft, zwei andere symmetrisch angeordnete Zylinder zu benutzen, in welchem Falle ein einziges Organ 11 vorhanden ist, das mit zwei Nuten 10, io1 versehen ist.To balance the machine, it is advantageous to use two other symmetrically arranged cylinders, in which case there is a single member 11 provided with two grooves 10, 10 1 .
