Description

Kompressor mit Schleuderschmierung und einer über die Einlaßventile zum Zylinder gestülpten Filterhaube Die Erfindung betrifft einen Kompressor mit Schleuderschmierung und einer über die Einlaßventile zum Zylinder gestülpten Filterhaube, bei dem zur Erzielung einer Kühlung durch Luftkreislauf der Raum über den Saugventilen mit dein ölangefüllten Kurbelraum durch Rohre verbunden ist, von denen das eine der durch die Filterhaube eingesaugten Luft in der Richtung zum Kurbelraum, das andere dieser Luft in der Richtung zu dem Raum über den Saugventilen dein Durchgang gestattet.Compressor with centrifugal lubrication and one via the inlet valves The invention relates to a compressor with Centrifugal lubrication and a filter hood slipped over the inlet valves to the cylinder, in which the space above the suction valves to achieve cooling by means of air circulation is connected to your oil-filled crankcase by pipes, one of which the air sucked in through the filter hood in the direction of the crankcase, the other of this air in the direction of the room above the suction valves of your passage allowed.

Es ist zwar schon bekannt, bei Kompressoren mit Schleuderschmierung an dem Rauar unter dem Kolben Lufteinlaß- und Ölrückschlagventile anzuordnen. Auch ist es bereits bekannt, diesen Raum mit der Filterhaube in Verbindung zu bringen, um so einen Druckausgleich zu erzielen. Es ist aber noch nicht vorgeschlagen worden, in der vorhin angegebenen Axt einen Luftkreislauf zu bewerkstdligen und die aus der Filterhaube angesaugte, in den Raum unter dem Kolben eintretende Luft von hier aus den Saugventilen zuzuführen. Dier sich so im Kreise bewegende Luftstrom wirkt kühlend, da die unter dem Kolben wegbewegte Luft nicht verdichtet, sondern nur weiterbefördert wird. Wird der Kompressor auf Leerlauf eingestellt, so bewegt er oberhalb des Kolbens überhaupt keine Luft. Wird aber durch die Saugventile Luft angesaugt, so wird sie dem erwähnten Kühlluftstrom entnommen. Eine besondere Wasserkühlung ist entbehrlich. Der Überschuß an kühlend wirkender Blasluft entweicht durch die Filterhaube nach außen, die also bei dem einen Kolbenhub Luft eir-und bei dem anderen Hub Luft austreten läßt.It is already known for compressors with centrifugal lubrication to arrange air inlet and oil check valves on the Rauar under the piston. Even is it already known to associate this space with the filter hood, to achieve such a pressure equalization. But it has not yet been suggested to accomplish an air circuit in the ax mentioned above and the out air sucked into the filter hood and entering the space under the piston from here feed from the suction valves. The air flow moving in a circle acts cooling, as the air moving away from under the piston does not compress, but only transports it further will. If the compressor is set to idle, it moves above the piston no air at all. But if air is sucked in through the suction valves, it will taken from the cooling air flow mentioned. A special water cooling is not necessary. The excess of cooling blowing air escapes through the filter hood outside, which means that air eir in one piston stroke and air emerges with the other stroke leaves.

Ein Luftverdichter gemäß der Erfindung ist in der Abbildung in einer beispielsweisen Ausführungsform schematisch in senkrechtem Schnitt dargestellt. Hierbei ist i die übergestülpte Filterhaube, 2 eine in ihr liegende, die Saugventile überdeckende ringförmige Haube, als Kühlmantel dienend. 3 ist das Blasventilgehäuse, q. der freie Ringraum zwischen 2 und 3. 5 sind die Saug-, 6 die Blasventile. 7 und 8 sind zwei den Raum oberhalb der Saugventile mit dein Raum unterhalb des Kolbens 9 verbindende Rohre. Letzterer Raum ist mit io bezeichnet. In die Rohre y und 8 sind Ventile i i und 12 eingebaut, von denen ersteres Luft nur in Richtung 2, i o, letzteres nur in umgekehrter Richtung i o, 2 durchtreten läßt.An air compressor according to the invention is shown in a exemplary embodiment shown schematically in vertical section. Here i is the slipped-over filter hood, 2 one lying in it, the suction valves Covering ring-shaped hood, serving as a cooling jacket. 3 is the blow valve housing, q. the free annular space between 2 and 3. 5 are the suction valves, 6 are the blowing valves. 7 and 8 are two the space above the suction valves with your space below the piston 9 connecting pipes. The latter room is labeled io. In pipes y and 8 valves i i and 12 are installed, of which the former air only in direction 2, i o, the latter only allows i o, 2 to pass in the opposite direction.
