Description
Steuerung für doppeltwirkende, schwungradlose Kolbenkraftmaschinen. Steuerungen für doppeltwirkende, schwungradlose Kolbenkraftmaschinen mit einem vom Arbeitskolben bewegten Hilfsschieber und einem Stufenkolben als Hauptschieber, dessen innere Kanten den Auslaß, und dessen Außenkante am kleineren Kolben den Einlaß für eine Zylinderseite steuern, sind bekannt. Von diesen bekannten Steuerungen unterscheidet sich der Erfindungsgegenstand dadurch, @daß der größere Steuerkolben außen durch eine Wand abgeschlossen ist, idaß der Stufenkolben selbst hohl ausgebildet ist und durch Öffnungen im größeren Steuerkolben zur Zuleitung des Treibmittels für die andere Zylinderseite dient.Control for double-acting, flywheelless piston engines. Controls for double-acting, flywheelless piston engines with one of the Working piston moved auxiliary slide and a stepped piston as the main slide, its inner edges the outlet, and its outer edge on the smaller piston the inlet for control a cylinder side are known. It differs from these known controls the subject of the invention in that @ that the larger control piston through the outside a wall is completed, idass the stepped piston itself is hollow and through openings in the larger control piston for supplying the propellant for the other cylinder side is used.
Der erreichte Erfolg gegenüber den bekannten Steuerungen lieb in der Einfachheit und Kürze der Treibmittelführung; der auf ein Mindestmaß gebrachte Kanalinhalt begünstigt sowohl die Wirtschaftlichkeit als auch die ischnelle Wirkung ;der Steuerung, außerdem erhält man ein sehr einfaches Modiell für den Schieberkasten.The success achieved compared to the well-known controls dear to the Simplicity and brevity of the propellant supply; the canal content reduced to a minimum favors both economic efficiency and rapid effect; the control, in addition, a very simple model for the valve body is obtained.
In den Abbildungen der Zeichnung sind Ausführungsbeispiele gegeben, und es bedeutet: a Arbeitszylinder, b Arbeitskolben, c Hilfsschieber, d Rückschlagventil, e Bohrung im Zylindermantel, f Leitung zum Hilfsschieber, g Leitung von Ader Steuerkammer des Hilfisschiebers zu der des Hauptschvebers, h Hilfsauslaßleitung, i Hauptauslaßleitung, k Hauptschieber (.mit dem mittleren Steuerkolben q für Verbundmaschinen), l und wa Leitkanäle von und zu. den Arbeitskolben, o Steuerkammer des Hauptschiebers, pTreibmittelzuführung.The figures in the drawing show exemplary embodiments and mean: a working cylinder, b working piston, c auxiliary slide, d check valve, e bore in the cylinder jacket, f line to the auxiliary slide, g line from the control chamber of the auxiliary slide to that of the main slide, h auxiliary outlet line, i main outlet line, k main slide (.with the central control piston q for compound machines), l and wa guide channels from and to. the working piston, o control chamber of the main slide, p propellant supply.
Die Wirkungsweise der Steuerung ist folgende: Die Steuerkammer o wind vermittels des Hilfsschiebers c, ider vom Arbeitskolben b beeinflußt wird, abwechselnd durch Leitung e, f, g dem Treibmitteldruck ausgesetzt und durch Leitung g, h, i von diesem entlastet; infolgedessen läßt der Hauptschieber k das zuströmende Treibmittel abwechselnd durch Kanal in oder L auf den Arbeitskolben b wirken, während er Idas verbrauchte Treibmittel abwechselnd durch L oder m in :die Ableitung i entweichen läßt.The operation of the control is as follows: The control chamber o winds by means of the auxiliary slide c, which is influenced by the working piston b, alternately exposed to the propellant pressure through lines e, f, g and relieved of this through lines g, h, i; As a result, the main slide k lets the inflowing propellant act alternately through the channel in or L on the working piston b , while it lets Idas used propellant escape alternately through L or m in: the derivative i.
In Abb. a ist als Ausführungsbeispiel eine Tandemverhundinaschine dargestellt; der Hauptschieber k eignet sich in der gezeichneten Form auch für nebeneinanderliegende Verbundmaschinen. Gegenüber den bisher bekannten, kraftschlüssig bewegten und als Stufenkolben ausgebildeten Hauptschiebern für Verbundmaschinen besteht ein wesentlicher Vorteil darin, @daß zur Steuerung des Treibmittelaüslasses nur ein Kolben q dient.In Fig. A, a tandem dog machine is an exemplary embodiment shown; the main slide k in the form shown is also suitable for adjacent ones Compound machines. Compared to the previously known, non-positively moved and as Stepped piston designed main slide valve for compound machines is an essential one The advantage is that only one piston q is used to control the propellant outlet.
