Description
Rotationskompressor mit in einem Gehäuse mit zylindrischer Bohrung exzentrisch zur Zylinderachse beidseitig gelagertem zylindrischem Rotor. Die Erfindung betrifft einen Rotations kompressor mit einem in einem Gehäuse mit zylindrischer Bohrung exzentrisch zur Zylinderachse beidseitig gelagertem zylin drischem Rotor.
Gemäss der Erfindung ist in dem Rotor ein Schieber vorgesehen, dessen auf der Ge häusebohrung gleitende Fläche die gleiche Krümmung besitzt wie die Gehäusebohrung und welcher zentrisch zur Gehäusebohrung drehbar gelagert ist.
Ein Kompressor dieser Art zeichnet sich durch grösste Einfachheit der Konstruktion aus. Alle Teile sind zwangsläufig geführt, wobei die umlaufenden Teile einander nicht zu berühren brauchen. Infolgedessen eignet sich dieser Kompressor für die höchsten Drehzahlen.
Auf der Zeichnung ist eine Ausführungs form Lies Kompressors gemäss der Erfindung beispielsweise dargestellt, und zwar zeigt: Abb. 1 einen Querschnitt durch die Mitte des Gehäuses und Rotors, Abb. 2 einen Längsschnitt durch Ge häuse und Rotor, Abb. 3 eine Stirnansicht des Kompres- sors, Abb. 4 einen Grundriss der Druckventil- platte für sich,
Abb. 5 einen Längsschnitt und Abb. 6 einen Querschnitt durch das Druckventil.
Im zylindrischen Gehäuse .1 ist ein zylin drischer Rotor 2 drehbar angeordnet und exzentrisch zur Achse des Gehäuses 1 in bei den .Seitendeckeln 3 gelagert. Im Rotor ist ein Schlitz 4 vorgesehen, in welchem der Schieber 5 zwischen zwei halbrunden Füh rungsstücken 6 hin- und hergleiten und sich dem drehbaren Rotor 2 anpassen kann. Der Schieber 5 besitzt an beiden Seitenenden je eine runde Scheibe 7, welche Scheiben der art gebaut sind, dass sie die auf den Schie ber 5 wirkenden Zentrifugalkräfte ausglei chen. An beiden Scheiben 7 ist je ein An satz vorgesehen, welcher die Kugellager auf- nimmt. Der Schieber 5 ist zentrisch zur Ge häuseachse in beiden Seitendeckeln 3 dreh bar -gelagert und an seinem Umfang ent sprechend der Gehäusebohrung geschliffen.
Am Gehäuse 1. ist eine Saugöffnung 8 angeordnet, der gegenüber sich die Druck öffnung 9 mit einem in derselben eingebau ten Zylinderplattenventil 1.0 befindet. Zwi schen der Saug- und Drucköffnung ist die Gehäusebohrung dem Rotorradius entspre chend tiefer eingeschliffen, um eine mög lichst breite Dichtungsfläche zwischen Ro tor 2 und Gehäuse 1 zu erzielen. Dabei wird, während der Schieber die Dichtungsfläche 11. durchläuft, eine gute Schmierung desselben erzielt, da im Spalt 16 zwischen Schieber und der Dichtungsfläche 11 ein dicker Öl film entsteht.
Durch die in jedem Seiten deckel 3 befindlichen Öffnungen 12 wird das Schmiermittel eingepresst, um durch die Nu ten 13 an der Innenseite der Deckel 3 an die Seitenflächen 14 des Rotors 2 zu ge langen. Durch die Öffnung 15 in jedem Deckel 3 wird das Öl zurück zum Ölbehälter, welcher nichteingezeichnet ist, geleitet.
Hat der Schieber 5 die Dichtungsfläche 11 in der Pfeilrichtung passiert, so wird durch die Saugöffnung .8 Frischgas ange saugt und das vor dem Schieber 5 im Raum 17 befindliche Gas verdichtet. Dieses hoch verdichtete Gas wird durch die Schlitze 18 und 19 und das Plattenventil 10 zur Drucköffnung 9 gepresst, von wo das Gas an seinen Bestimmungsort gelangen kann. Das Plattenventil 10 hat eine zylindrische Ge stalt und sitzt in einer zylindrischen Boh rung des Gehäuses 1.
Der Ventilkörper be steht aus zwei Segmentkörpern 21, 22 mit je einem Boden 23, 24, welche Böden in einem kleinen Abstand voneinander liegen und mit versetzt zueinander angeordneten Öffnungen versehen sind. Über den Öffnun gen des Bodens 24 ist eine Platte 25 an geordnet, die durch eine gebogene, sich mit ihrer andern Seite gegen den Boden 23 ab stützende Federplatte 26 gegen den Boden 24 gepresst wird.
In der Platte 25 befinden sich Öffnungen 27, die versetzt zu den Off- nungen des Bodens 24 liegen, so dass das Druckgas nur dann durch die Öffnungen 27 hindurchtreten kann, wenn die Platte 2.5 ent gegen dem Druck .der Federplatte 26 an gehoben ist. Der Segmentkörper 22 ist in wendig durch eine Längswand 20 in zwei Abteilungen getrennt, in deren jede das Gas durch Öffnungen eintritt, die mit den Aus trittsöffnungen 18 bezw. 19 des Gehäuses 1 in unmittelbarer Verbindung stehen.
Bei die ser Anordnung der Öffnungen 18, 19 und der Längswand 20 wird in der Anfangs druckperiode die Freilegung eines grossen Querschnittes zur Druckleitung 9 gewähr leistet, während gegen Ende der Druck periode die hochgespannten Gase restlos durch die hintern Öffnungen 19 ausgestossen werden.
Rotary compressor with a cylindrical rotor mounted on both sides in a housing with a cylindrical bore eccentrically to the cylinder axis. The invention relates to a rotary compressor with a cylindrical rotor mounted eccentrically to the cylinder axis in a housing with a cylindrical bore on both sides.
According to the invention, a slide is provided in the rotor, the surface of which sliding on the housing bore has the same curvature as the housing bore and which is rotatably mounted centrally to the housing bore.
A compressor of this type is characterized by the greatest simplicity of construction. All parts are inevitably guided, whereby the rotating parts do not need to touch each other. As a result, this compressor is suitable for the highest speeds.
The drawing shows an embodiment Lies compressor according to the invention, for example, showing: Fig. 1 a cross section through the center of the housing and rotor, Fig. 2 a longitudinal section through Ge housing and rotor, Fig. 3 an end view of the compressor - sors, Fig. 4 a floor plan of the pressure valve plate for itself,
Fig. 5 is a longitudinal section and Fig. 6 is a cross section through the pressure valve.
In the cylindrical housing .1 a cylindrical rotor 2 is rotatably arranged and eccentrically to the axis of the housing 1 in the .Seitendeckeln 3 mounted. A slot 4 is provided in the rotor, in which the slide 5 can slide back and forth between two semicircular Füh approximately pieces 6 and can adapt to the rotatable rotor 2. The slide 5 has a round disk 7 at both ends, which disks are constructed in such a way that they compensate for the centrifugal forces acting on the slide 5. An attachment is provided on each of the two disks 7, which takes up the ball bearings. The slide 5 is centric to the Ge housing axis in both side covers 3 rotatably -beared and ground on its circumference accordingly of the housing bore.
On the housing 1. a suction opening 8 is arranged, which is opposite the pressure opening 9 with a cylinder plate valve 1.0 built into the same. Between tween the suction and pressure opening, the housing bore is ground in correspondingly deeper to the rotor radius in order to achieve the widest possible sealing surface between Ro tor 2 and housing 1. In this case, while the slide passes through the sealing surface 11, good lubrication of the same is achieved, since a thick oil film is formed in the gap 16 between the slide and the sealing surface 11.
Through the openings 12 located in each side cover 3, the lubricant is pressed in to long through the Nu th 13 on the inside of the cover 3 to the side surfaces 14 of the rotor 2. Through the opening 15 in each cover 3, the oil is fed back to the oil container, which is not shown.
If the slide 5 has passed the sealing surface 11 in the direction of the arrow, fresh gas is sucked in through the suction opening .8 and the gas located in front of the slide 5 in space 17 is compressed. This highly compressed gas is pressed through the slots 18 and 19 and the plate valve 10 to the pressure opening 9, from where the gas can reach its destination. The plate valve 10 has a cylindrical shape and sits in a cylindrical borehole of the housing 1.
The valve body consists of two segment bodies 21, 22 each with a bottom 23, 24, which bottoms are at a small distance from each other and are provided with mutually offset openings. About the openings of the bottom 24, a plate 25 is arranged, which is pressed against the bottom 24 by a curved spring plate 26 that supports itself with its other side against the bottom 23 from.
In the plate 25 there are openings 27 which are offset from the openings in the bottom 24, so that the compressed gas can only pass through the openings 27 when the plate 2.5 is raised against the pressure of the spring plate 26. The segment body 22 is in maneuverable separated by a longitudinal wall 20 into two compartments, in each of which the gas enters through openings that are respectively with the out openings 18. 19 of the housing 1 are in direct contact.
In the water arrangement of the openings 18, 19 and the longitudinal wall 20, the exposure of a large cross section to the pressure line 9 is guaranteed in the initial printing period, while the high-tension gases are completely expelled through the rear openings 19 towards the end of the printing period.
