KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, bei mehrzylindrigen Kolbenverdichtern für elastische Mittel mit mehreren Druckstufen (Verbundverdichtern) für sämtliche Druckstufen gleich große Zylinder zu verwenden, indem man die niederen Druckstufen auf so viele Zylinder verteilt, daß jeder Einzelzylinder die gleiche Größe wie der Hochdruckzylinder erhält. Dadurch erzielt man den Vorteil, für sämtliche Zylinder das gleicheIt is known in multi-cylinder piston compressors for elastic means with several Pressure stages (compound compressors) for all pressure stages cylinders of the same size to use by distributing the lower pressure levels to as many cylinders as each Single cylinder is given the same size as the high pressure cylinder. This is how you achieve the advantage of the same for all cylinders
ίο Modell benutzen zu können, während sich der betriebstechnische Vorteil eines nahezu vollständigen Massenausgleichs ergibt.ίο being able to use the model while the operational advantage of an almost complete mass balance results.
Der Nachteil, den eine derartige Maschine besitzt, besteht darin, daß die Verteilung des Treibmittels auf Hoch- und Niederdruckstufen durch die verhältnismäßig geringe Zahl der Zylinder nur wenige Abänderungen zuläßt. Dieser Nachteil wird durch die Erfindung ber hoben. Danach werden die Niederdruckzylinder außer mit Saugventilen auch mit Einlaßschlitzen versehen, so daß man ein und dieselbe Maschinentype durch Verlegen der Einlaßschlitze relativ zum Hubende oder auch durch völliges Schließen, derselben für verschiedene Leistungsverteilung zwischen Hoch- und Niederdruckzylinder benutzen kann.The disadvantage that such a machine has is that the distribution of the Propellant at high and low pressure levels due to the relatively small number of Cylinder allows only a few changes. This disadvantage is over by the invention lifted. Thereafter, the low-pressure cylinders are not only equipped with suction valves but also with inlet slots provided, so that one and the same machine type can be obtained by relocating the inlet slots relative to the end of the stroke or through complete closing, the same for different ones Can use power distribution between high and low pressure cylinders.
. In der Zeichnung ist ein Ausführungsbeispiel. In the drawing is an exemplary embodiment
■ für die Erfindung dargestellt, und zwar ein zweistufiger Verdichter mit vier gleichen Zylindern. Die Luft wird zunächst von den drei Niederdruckzylindern nv n2, ns durch in der Zeichnung nicht sichtbare Saugventile und durch die Einlaßschlitze s angesaugt und in den Aufnehmer α gedrückt und dann vom Hochdruckzylinder h auf den gewollten Enddruck gebracht. Der Antrieb erfolgt durch einen Elektromotor, der an der Hochdruckseite bei e angekuppelt ist und genügend Schwungmasse enthält, um einen stoßfreien Betrieb zu erzielen. Um einen möglichst vollkommenen Massenausgleich zu erzielen, sind die Kurbeln der Zylinder h und nr gleichlaufend und gegen diejenigen der gleichlaufenden Zylinder n% und M3 um 180° versetzt. Die Kurbelwelle w ist an drei Stellen gelagert und in ein Gehäuse g eingeschlossen.■ shown for the invention, namely a two-stage compressor with four identical cylinders. The air is first sucked in by the three low pressure cylinders n v n 2 , n s through suction valves (not visible in the drawing) and through the inlet slots s and pressed into the transducer α and then brought to the desired final pressure by the high pressure cylinder h. It is driven by an electric motor, which is coupled to the high pressure side at e and contains enough flywheel to achieve smooth operation. In order to achieve as perfect a mass balance as possible, the cranks of the cylinders h and n r are synchronized and offset by 180 ° from those of the synchronous cylinders n % and M 3. The crankshaft w is supported in three places and enclosed in a housing g.
