Description

Gegenstand der Erfindung ist ein Drehkolbenverdichter mit verschiebbaren Trennschiebern.The invention relates to a rotary piston compressor with displaceable Slide gate valves.

In der Zeichnung ist der Gegenstand der Erfindung beispielsweise veranschaulicht, und zwar zeigt Fig. I den Verdichter in Längsansicht, die obere Hälfte im Längsschnitt, Fig. 1I den Verdichter im Querschnitt A-B der Fig. I, Fig. III den Verdichter im Schnitt C-D der Fig. II, Fig. IV einen Trennschieber in Ansicht und im Schnitt E-F, Fig. V einen Ausschnitt des Gehäuses in Ansicht und Fi,g. VI einen Ausschnitt des Deckels in Ansicht. Der Verdichter besteht aus dem Gehäuse i mit dem Einsatz 2, dem Gehäusedeckel 4 mit dem Einsatz 5, dem Kolben 3 und den Trennschiebern 6. Die Trennschieber 6 bestehen aus Preßstoff mit Gewebeeinlage und die Einsätze 2 und 5 aus härterem \laterial als die Gehäuseteile i und 4. In dem Deckel 4 befindet sich der Einlaufkanal8 und in dem Gehäuse i der Ausströmkanal io. Die Trennschieber 6 mit Aussparungen 7 sind in dem Kolben 3 längs verschiebbär gelagert. In der Mitte der Aussparung 7 des Kolbens 3 befinden sich Auslaufkanäle 9. Der Kolben 3 ist in seinem Außendurchmesser kleiner als der Innendurchmesser des Gehäuseeinsatzes 2. Er ist außerhalb der Mitte des Gehäuses i gelagert und berührt nur an einer Stelle die Lauffläche des Gehäuseeinsatzes 2. Durch die Anordnung des Kolbens 3 entsteht ein Saugraum A und ein Druckraum h. Der Gehäuseeinsatz 2 hat einen elliptischen Querschnitt. Dadurch ist der Saugraum A größer als der Druckraum h. Bei der Drehung des Kolbens gleiten die Trennschieber 6 an den Laufflächen des Gehäuseeinsatzes 2 entlang, wobei die Aussparungen 7 als Saug- und Druckventile wirken. Durch die Drehung des Kolbens strömt die Luft aus dem Kanal 8 und durch die Aussparung 7 der Trennschieber 6 in den Ansaugraum A, wird durch die Trennschieber 6 in den Druckraum h gedrückt und, in demselben verdichtet, durch die Kanäle 9 des Kolbens 3 in den Kanal io des Gehäuses i abgeleitet.In the drawing, the subject matter of the invention is illustrated, for example, namely Fig. I shows the compressor in a longitudinal view, the upper half in a longitudinal section, Fig. 1I the compressor in cross section A-B of Fig. I, Fig. III the compressor in Section C-D of Fig. II, Fig. IV a slide gate in view and in section E-F, Fig. V shows a detail of the housing in view and Fi, g. VI a section of the Lid in view. The compressor consists of the housing i with the insert 2, the housing cover 4 with the insert 5, the piston 3 and the slide gate 6. The Separating slide 6 are made of molded material with a fabric insert and the inserts 2 and 5 made of harder material than the housing parts i and 4. Located in the cover 4 the inlet channel8 and in the housing i the outlet channel io. The slide gate 6 with recesses 7 are mounted in a longitudinally displaceable manner in the piston 3. In the middle the recess 7 of the piston 3 are outlet channels 9. The piston 3 is in its outer diameter is smaller than the inner diameter of the housing insert 2. It is stored outside the center of the housing i and only touches at one point the running surface of the housing insert 2. The arrangement of the piston 3 creates a suction space A and a pressure space h. The housing insert 2 has an elliptical one Cross-section. As a result, the suction space A is larger than the pressure space h. When turning of the piston slide the slide gate 6 on the running surfaces of the housing insert 2 along, the recesses 7 acting as suction and pressure valves. Through the Rotation of the piston, the air flows out of the channel 8 and through the recess 7 of the Separating slide 6 into the suction chamber A, is through the separating slide 6 into the pressure chamber h pressed and, compressed in the same, through the channels 9 of the piston 3 in the Channel io of the housing i derived.

Durch leichte Schmierung und Kühlrippen am Umfang des Gehäuses i wird ein Heißlaufen der Trennschieber 6 verhütet.Light lubrication and cooling fins on the circumference of the housing i Prevents the slide gate 6 from overheating.
