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.
