Description

Luftkompressor, bei dem das Saugventil durch einen Kanal mit dem Zylinderraum verbunden ist. Die vorliegende Erfindung bezieht sich auf solche Luftkompressoren, die Luft von annähernd dem Atmosphärendrucke auf verhältnismäßig hohe Spannungen verdichten, wie solche z. B. beim Betriebe von Eisenbahndruckluftbremsen oder zu ähnlichen Zwecken verwendet werden, und wobei die Wirkung der Kompressoren mit einer erheblichen Temperaturerhöhung der verdichteten Luft verbunden ist, die besonders am Ende des Verdichtungsvorganges auftritt.Air compressor in which the suction valve is connected to the cylinder chamber through a duct connected is. The present invention relates to such air compressors, the air from approximately atmospheric pressure to relatively high voltages compress, such as such. B. when operating railway air brakes or to Similar purposes can be used, and taking the action of the compressors with a considerable increase in temperature of the compressed air is connected to that particularly occurs at the end of the compression process.

Bei derartigen Luftkompressoren ist es zweckmäßig, die Saugventile gegen den Einfluß des verhältnismäßig hohen Druckes und der hohen Erwärmung der geförderten Luft zu schützen, die gegen Ende des Verdiehtungshubes eintreten, damit Luftverluste und Verminderungen des Wirkungsgrades vermieden werden. Die vorliegende Erfindung bezweckt, dafür geeignete Mittel anzugeben.In such air compressors, it is advisable to use the suction valves against the influence of the relatively high pressure and the high heating of the to protect the conveyed air towards the end of the compression stroke enter, so that air losses and reductions in efficiency are avoided. The present The purpose of the invention is to provide suitable means for this.

Die Zeichnung stellt eine Ausführungsform der Erfindung an einem teilweise im Querschnitt gezeichneten Luftkompressor dar. Der Zylinder des Kompressors .ist mit i bezeichnet, der Kolben mit 2, das Druckventil mit 3 und das Saugventil mit q.. Die Ventile sind 'in bekannter Weise im Zylinderdeckel 5 angeordnet.The drawing illustrates an embodiment of the invention in part air compressor drawn in cross section. The cylinder of the compressor .ist with i, the piston with 2, the pressure valve with 3 and the suction valve with q .. The valves are arranged in the cylinder cover 5 in a known manner.

Um den Zufluß der durch den Kolben :2 verdichteten Luft nach dem Saugventil möglichst zu verhindern, wird dieses Ventil nach der Erfindung mit der Kolbenkammer durch einen vom Kolben 2 überlaufenen Kanal 6 verbunden, der in einer bestimmten Entfernung vom Ende des Kompressionshubes des Kolbens 2 in die Kolbenkammer mündet, so daß der Kolben schon vor Erreichung seines vollen Kompressionshubes den Durchgang durch den Kanal 6 nach dem Saugventil q. abschließt, indem die Kolbendichtungen über die Mündung des Kanals 6 hinweggehen. Dadurch wird das Entweichen von Druckluft aus der Kolbenkammer durch das Saugventil q. zur Zeit des stärksten Zusammenpressens der Luft im Zylinder i verhindert. Die Luftverluste werden also erheblich vermindert und der Wirkungsgrad des Kompressors erheblich erhöht.To the inflow of the air compressed by the piston: 2 after the suction valve to prevent as much as possible, this valve according to the invention with the piston chamber connected by a channel 6 overflowed by the piston 2, which in a certain Distance from the end of the compression stroke of the piston 2 opens into the piston chamber, so that the piston will pass through before it has reached its full compression stroke through the channel 6 after the suction valve q. completes by removing the piston seals go over the mouth of the channel 6. This prevents compressed air from escaping from the piston chamber through the suction valve q. at the time of the strongest compression prevents the air in cylinder i. The air losses are therefore considerably reduced and the efficiency of the compressor is increased significantly.

Die Erfindung beschränkt sich natürlich nicht auf die in dem Ausführungsbeispiel dargestellten Bauteile, sondern bietet auch z. B. bei. anderen Ventilarten, Kolbenventilen u. dgl., die vorstehend angegebenen oder noch größere Vorteile; denn die zuletzt genannten Ventile neigen an sich noch mehr zu Undichtigkeiten als die in der Zeichnung dargestellte Bauart.The invention is of course not limited to that in the exemplary embodiment illustrated components, but also offers z. B. at. other types of valves, piston valves and the like, the advantages indicated above or greater; because the last The valves mentioned tend to leak even more than those in the drawing shown design.
