    Ventlllo88 Schieberateuerung für Kompre88oren.   



   Die Erfindung bezieht sich auf eine ventillose Schiobersteuerung für Kompressoren und besteht im wesentlichen darin, dass der Druckkanal nicht wie bisher im toten Punkte des Kolbenhubes geschlossen wird, sondern vorher. Dadurch wird erreicht, dass die im Arbeitszylinder eingeschlossene Luft vom Zeitpunkte des Druckkanalabschlusses bis zur   Kolbfntotpunktlage   weiter verdichtet wird und diese Luft beim Kolbenrückgange arbeitleistend wieder expandiert. Dies hat bei hohen Umlaufzahlen einen weichen Gang der Maschine zur Folge. 



   Die Zeichnung stellt das Schieber-und Indikatordiagramm dar. Vom Punkte 1 bewegt sich der Kolben nach rechts während der Expansion der Luft beim geschlossenen Arbeitszylinder. Im Punkte 2 öffnet der Schieber den Saugraum, der über den rechten Totpunkt 3 bis zum Punkte 4 offen bleibt. 4 bis 5 ist die Verdichtung der Luft beim geschlossenen Arbeitszylinder. Im Punkte 5 öffnet der Schieber den Druckraum und von 5 bis 6 wird die verdichtete Luft in den   Drurkraum   hinausgeschoben. Im Punkte 6 schliesst der Schieber den Druckraum. Infolgedessen wird die abgeschlossene Luft im Arbeitszylinder von 6 bis 1 weiter verdichtet.

    Ventlllo88 slide control for compressors.



   The invention relates to a valveless slide control for compressors and consists essentially in the fact that the pressure channel is not closed at the dead point of the piston stroke, as before, but before. This ensures that the air enclosed in the working cylinder is further compressed from the point in time at which the pressure channel is closed up to the piston dead center and this air expands again while the piston retracts. This results in the machine running smoothly with high numbers of revolutions.



   The drawing shows the slide and indicator diagram. From point 1 the piston moves to the right during the expansion of the air when the working cylinder is closed. At point 2, the slide opens the suction chamber, which remains open via right dead center 3 to point 4. 4 to 5 is the compression of the air in the closed working cylinder. At point 5 the slide opens the pressure chamber and from 5 to 6 the compressed air is pushed out into the pressure chamber. At point 6, the slide closes the pressure chamber. As a result, the closed air in the working cylinder from 6 to 1 is further compressed.

PATENT-ANSPRUCH : Ventillose Schiebersteuerung für Kompressoren, dadurch gekennzeichnet, dass der Schieber den Druckkanal vor der Totpunktlage des Kolbens schliesst, so dass die Luft, die bis zur Erreichung der Totpunktlage weiter verdichtet wird, beim Rückgang des Kolbens arbeitleistotid expandieren kann, wodurch, insbesondere bei hohen Umlaufzahlen, ein weicher Gang des Kompressors erzielt wird. EMI1.1 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Valveless slide control for compressors, characterized in that the slide closes the pressure channel before the dead center position of the piston, so that the air, which is further compressed until the dead center position is reached, can expand as the piston retracts, whereby, especially with high circulation rates, a soft gear of the compressor is achieved. EMI1.1 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
