Description

BESCHREIBUNG  DESCRIPTION
Auslasslamellenventil Auslasslamellenventil
Die Erfindung betrifft ein Auslasslamellenventil, insbesondere ein Lamellenventil zum Verschließen und Öffnen einer Auslassöffnung in einem Gehäuse eines Kompressions- zylinders eines Kompressors. The invention relates to an outlet flap valve, in particular a flap valve for closing and opening an outlet opening in a housing of a compression cylinder of a compressor.
Kompressoren werden beispielsweise in Bremsanlagen von Bussen oder Lastkraftwa- gen verwendet. Solche Kompressoren weisen einen oder mehrere Kompressionszylin- der auf und sind direkt an dem Motor des Fahrzeugs angebracht. Häufig werden Hub- kolbenkompressoren verwendet, die einen Arbeitszyklus mit einem Ansaugen, einem Verdichten und einem Ausstößen von Luft aufweisen. Im Betrieb des Kompressors wird einerseits aufgrund einer Kompressionsarbeit und andererseits aufgrund von mechani- schen Verlusten, wie beispielsweise einer Reibung der Kolbenringe oder von Drossel- verlusten eines Lamellenventils, über den Fahrzeugmotor Energie verbraucht. Heutzu- tage ist jedoch Energieeinsparung eine hauptsächliche Herausforderung. Compressors are used, for example, in brake systems of buses or trucks. Such compressors have one or more compression cylinders and are mounted directly on the engine of the vehicle. Frequently, reciprocating compressors are used which have a duty cycle with suction, compression and expulsion of air. During operation of the compressor, energy is consumed via the vehicle engine on the one hand due to compression work and on the other hand due to mechanical losses, such as, for example, friction of the piston rings or throttling losses of a disk valve. However, today, energy conservation is a major challenge.
Im Stand der Technik sind Auslasslamellenventile bekannt, die, wie in Fig. 1, Fig. 2a und Fig. 2b gezeigt, aus einer Lamelle 1 , die Auslassöffnungen 4 eines Kompressions- zylinders in einem Gehäuse 9 des Kompressionszylinders verschließt und öffnet, aus einer Brücke 2, die eine Verformung der Lamelle 1 in einem geöffneten Zustand der Auslassöffnungen 4 einschränkt, und aus Befestigungselementen 3 bestehen. Wenn ein Kolben in dem Kompressionszylinder nach unten geht, blockiert das Auslasslamel- lenventil die Auslassöffnungen 4, um zu verhindern, dass bereits ausgestoßene, unter Druck stehende, Luft wieder in den Kompressionszylinder zurückströmt. Wenn der Kol- ben nach oben geht, wird die Lamelle 1 durch den Luftstrom von der Auslassöffnung weggebogen, um Luft in einen Auslasskanal ausströmen zu lassen. Der maximale Krümmungsradius der weggebogenen Lamelle 1 , die sich an der Brücke 2 abstützt, ist in Fig. 2a mit y angegeben. Wie oben angegeben, wird ein Teil der Energie der verdich- teten Luft dazu verwendet, die Lamelle 1 zu biegen. Von dem Gehäuse 9 des Kompressionszylinders ist hier eine Ventilplatte dargestellt, die an einem Zylinderblock angebracht ist. Alternativ ist aber nicht zwingend eine sepa- rate Ventilplatte erforderlich und die Funktion der separaten Ventilplatte kann von einem in dem Gehäuse 9 des Kompressionszylinders integrierten Abschnitt ausgeübt werden. In the prior art are known Auslasslamellenventile, which, as shown in Fig. 1, Fig. 2a and Fig. 2b, from a lamella 1, the outlet openings 4 of a compression cylinder in a housing 9 of the compression cylinder closes and opens, from a bridge 2, which restricts a deformation of the lamella 1 in an opened state of the outlet openings 4, and consist of fastening elements 3. When a piston descends in the compression cylinder, the discharge louver valve blocks the discharge ports 4 to prevent the already exhausted pressurized air from flowing back into the compression cylinder. As the piston goes up, the louver 1 is deflected away from the exhaust port by the flow of air to expel air into an exhaust passage. The maximum radius of curvature of the bent-away blade 1, which is supported on the bridge 2, is indicated in Fig. 2a with y. As indicated above, part of the energy of the compressed air is used to bend the fin 1. Of the housing 9 of the compression cylinder, a valve plate is shown here, which is attached to a cylinder block. Alternatively, however, a separate valve plate is not absolutely necessary and the function of the separate valve plate can be exerted by a section integrated in the housing 9 of the compression cylinder.
Um den Druckabfall an den Auslasslamellenventilen, der wesentlich für einen Energie- verbrauch ist, zu verringern ist es erforderlich, eine Auslassfläche des Auslassventils zu vergrößern. In order to reduce the pressure loss at the outlet louver valves, which is essential for energy consumption, it is necessary to increase an outlet area of the exhaust valve.
Dies ist grundsätzlich durch ein Vergrößern der Verformung der Lamelle 1 möglich, so dass sich die Lamelle 1 weiter von den Auslassöffnungen 4 entfernt, also ein Hub a (Fig. 2a) vergrößert wird, und somit ein Auslassraum bzw. die Auslassfläche größer wird. Dabei verformt sich jedoch bei einem gegebenen Bauraum (den Abmessungen des Auslasskanals), der nicht vergrößert werden kann, die Lamelle 1 stärker und wird also mit einem geringeren Krümmungsradius gebogen. Dies führt jedoch zu einer Erhö- hung von Biegespannungen in der Lamelle 1 und somit zu einer Verringerung der Le- bensdauer der Lamelle 1. This is basically possible by increasing the deformation of the lamella 1, so that the lamella 1 is further away from the outlet openings 4, ie a stroke a (FIG. 2a) is increased, and thus an outlet space or the outlet area becomes larger. However, in the case of a given construction space (the dimensions of the outlet channel) which can not be enlarged, the lamella 1 deforms more strongly and is therefore bent with a smaller radius of curvature. However, this leads to an increase in bending stresses in the lamella 1 and thus to a reduction in the service life of the lamellae 1.
Die der Erfindung zugrunde liegende Aufgabe ist, ein Auslasslamellenventil bereitzu- stellen, das unter gegebenen maßlichen Randbedingungen einen Druckabfall an dem Auslasslamellenventil verringert. The object on which the invention is based is to provide an outlet lamella valve which reduces a pressure drop at the outlet lamella valve under given dimensional boundary conditions.
Die Aufgabe wird durch ein Auslasslamellenventil gemäß Anspruch 1 gelöst. Weiterent- wicklungen der Erfindung sind Gegenstand der abhängigen Ansprüche. The object is achieved by an outlet louver valve according to claim 1. Further developments of the invention are the subject of the dependent claims.
Durch ein Vorsehen von mindestens einer Öffnung für ein Befestigungselement in der Lamelle ist es möglich, eine Länge der Lamelle zu vergrößern, um einen maximalen Ab- stand von der Lamelle zu einer Auslassöffnung des Kompressionszylinders bei einem zumindest annähernd gleichen Krümmungsradius der Lamelle zu vergrößern. Die Be- festigungselemente können dann eine Brücke, die eine maximale Verformung der La- melle einschränkt und somit ihren maximalen Krümmungsradius bestimmt, an gegebe- nen Befestigungspunkten innerhalb der Lamelle befestigen, so dass kein zusätzlicher Raumbedarf zum Befestigen außerhalb der Lamelle entsteht. By providing at least one opening for a fastening element in the lamella, it is possible to increase a length of the lamella in order to increase a maximum distance from the lamella to an outlet opening of the compression cylinder with an at least approximately equal radius of curvature of the lamella. The fastening elements can then fix a bridge, which limits maximum deformation of the lamella and thus determines its maximum radius of curvature, to given fastening points within the lamella, so that no additional space is required for fastening outside the lamella.
Wenn die mindestens eine Öffnung vorteilhafterweise in einem Außenbereich der La- melle angeordnet ist, ist es möglich, die Auslassöffnung bezüglich der Lamelle an einer Stelle zu positionieren, wo die maximale Verformung der Lamelle am größten ist, um eine Auslassfläche so groß wie möglich zu gestalten. If the at least one opening is advantageously arranged in an outer region of the lamella, it is possible to arrange the outlet opening with respect to the lamella at one Position where the maximum deformation of the lamella is greatest to make an outlet area as large as possible.
Vorteilhafterweise sind zwei Öffnungen in der Lamelle vorgesehen. Damit ist es möglich die Brücke mit zwei Befestigungselementen sicher zu befestigen. Advantageously, two openings are provided in the lamella. This makes it possible to safely secure the bridge with two fasteners.
Die Lamelle hat vorteilhafterweise eine längliche Form, also eine Form, bei der eine Ab- messung in einer ersten Richtung gegenüber einer Abmessung in einer zweiten Rich- tung senkrecht zu der ersten Richtung wesentlich geringer ist. Die Öffnungen sind im Bereich von Enden in einer Längsrichtung, also der Richtung mit der großen Abmes- sung angeordnet. Dadurch ist es möglich, die Brücke mit einem großen Stützabstand sicher zu befestigen, ohne dass die Öffnungen in der Lamelle die Auslassöffnungen in einer verschlossenen Stellung der Lamelle freigeben. The lamella advantageously has an elongate shape, that is to say a shape in which a dimension in a first direction is substantially smaller than a dimension in a second direction perpendicular to the first direction. The openings are arranged in the region of ends in a longitudinal direction, that is to say the direction with the large dimension. This makes it possible to safely secure the bridge with a large support distance, without the openings in the lamella release the outlet openings in a closed position of the lamella.
Wenn die Brücke vorteilhafterweise mindestens ein Abströmloch aufweist, das in einem Bereich, der mit mindestens einer der Öffnungen der bestimmungsgemäß in der Brücke angeordneten Lamelle im Wesentlichen übereinstimmt, angeordnet ist, kann Luft, zu- sätzlich zu seitlichen Auslassflächen, durch die Öffnung(en) in der Lamelle über das Ab- strömloch in der Brücke abströmen. If the bridge advantageously has at least one outflow hole which is arranged in a region which substantially coincides with at least one of the openings of the lamella arranged as intended in the bridge, air, in addition to lateral outlet surfaces, can pass through the opening (s). in the slat over the discharge hole in the bridge.
Vorteilhafterweise sind die Öffnungen zu den Enden in der Längsrichtung hin offen. Da- bei besteht die Möglichkeit, die Öffnungen mit einer vergrößerten Querschnittsfläche für ein verbessertes Abströmen der Luft durch das Abströmloch zu nutzen. Advantageously, the openings are open to the ends in the longitudinal direction. It is possible to use the openings with an enlarged cross-sectional area for an improved outflow of air through the outflow hole.
Durch das vorteilhafte Vorsehen eines Durchgangslochs zusätzlich zu dem mindestens einen Abströmloch in der Brücke ist es möglich, sowohl die Brücke mittels der Befesti- gungselemente in dem Durchgangsloch zu befestigen als auch zusätzlich die Luft durch das Abströmloch abströmen zu lassen. By advantageously providing a through-hole in addition to the at least one outflow hole in the bridge, it is possible both to fix the bridge by means of the fastening elements in the through-hole and to additionally let the air flow out through the outflow hole.
Wenn die Öffnung vorteilhafterweise in einem zentralen Bereich der Lamelle angeord- net ist, besteht die Möglichkeit, die Lamelle in dem zentralen Bereich zu befestigen. So- mit kann sich die Lamelle in ihrem Randbereich an mehreren Stellen nach oben biegen, wodurch, verglichen zu den Befestigungen im Randbereich, sowohl mehrere Auslass- Öffnungen bzw. Auslassöffnungen mit einem größeren Gesamtquerschnitt freigegeben werden können als auch der Aufwand zum Befestigen der Brücke verringert wird, da das Befestigungselement nur an einer Stelle erforderlich ist. Vorteilhafterweise hat diese Lamelle eine längliche Form, so dass, bei einem Anordnen der Auslassöffnungen im Bereich der Enden in der Längsrichtung, der Flebelarm zum Verformen der Lamelle groß ist, um die Kraft zum Verformen der Lamelle und damit ei- nen Druckabfall zu reduzieren. Dabei wird durch eine Verdrehsicherung verhindert, dass sich die Lamelle verdreht, so dass die Auslassöffnungen in einem verschlossenen Zustand der Lamelle sicher verschlossen werden. If the opening is advantageously arranged in a central area of the lamella, it is possible to fix the lamella in the central area. As a result, the lamella can bend upwards at several points in its edge region, as a result of which a plurality of outlet openings or outlet openings with a larger overall cross-section can be released compared to the fastenings in the edge region and the outlay for fastening the bridge is reduced is because the fastener is required only in one place. Advantageously, this lamella has an elongated shape, so that, when arranging the outlet openings in the region of the ends in the longitudinal direction, the Flebelarm for deforming the blade is large in order to reduce the force for deforming the blade and thus a pressure drop. It is prevented by an anti-rotation, that the blade is rotated, so that the outlet openings are securely closed in a closed state of the blade.
Vorteilhafterweise ist die Verdrehsicherung als eine Erhöhung oder Vertiefung in der La- melle und einer zu der Erhöhung oder Vertiefung komplementären Vertiefung oder Er- höhung in dem Gehäuse des Kompressionszylinders vorgesehen. Eine Erhöhung oder Vertiefung in der Lamelle ist einfach durch ein Prägen oder einen ähnlichen Fertigungs- schritt herzustellen. Advantageously, the security against rotation is provided as an elevation or depression in the lamella and a depression or elevation complementary to the elevation or depression in the housing of the compression cylinder. An increase or depression in the lamella is easy to produce by embossing or a similar manufacturing step.

Räumliche Angaben wie, oben, unten, seitlich, oder ähnliche beziehen sich auf eine Be- schreibung eines Auslasslamellenventils das, wie in den Figuren dargestellt, oberhalb eines Kompressionszylinders angeordnet ist, und dessen Lamelle sich, wie ebenfalls in den Figuren dargestellt, nach oben bewegt. Diese Angaben sind aber nicht beschrän- kend. Spatial indications such as, top, bottom, side, or the like refer to a description of an outlet louver valve which, as shown in the figures, is located above a compression cylinder and whose lamella moves upwards as also shown in the figures , This information is not restrictive.
Fig. 3a zeigt eine seitliche Schnittansicht eines Auslasslamellenventils gemäß einer ersten Ausführungsform der Erfindung und Fig. 3b zeigt eine isometrische Ansicht des Auslasslamellenventils gemäß der ersten Ausführungsform der Erfindung. Das Auslass- lamellenventil ist vorgesehen, Auslassöffnungen (Fig. 1 : Bzz. 4) in einem Gehäuse (Fig. 1 : Bzz. 9) eines Kompressionszylinders eines Kompressors zu verschließen und zu öff- nen. 3a shows a side sectional view of an outlet fin valve according to a first embodiment of the invention, and FIG. 3b shows an isometric view of the outlet fin valve according to the first embodiment of the invention. The outlet louver valve is provided to close and open outlet ports (Fig. 1: Bz. 4) in a housing (Fig. 1: Bz. 9) of a compression cylinder of a compressor.
Die Ausführungsform des Auslasslamellenventils gemäß der Figuren 3a und 3b weist, wie der Stand der Technik gemäß den Figuren 1 , 2a und 2b, ebenfalls eine Lamelle 1 zum Verschließen und Öffnen einer hier nicht gezeigten Auslassöffnung (Fig. 1 : Bzz. 4) auf. Es kann eine einzelne Auslassöffnung vorgesehen sein oder alternativ mehrere Auslassöffnungen, wobei eine gesamte Querschnittsfläche der Auslassöffnungen mög- lichst groß gewählt werden sollte, um einen Druckverlust beim Ausstößen der Luft zu minimieren. Das Auslasslamellenventil weist ferner eine Brücke 2 auf, um eine Verformung der La- melle 1 einzuschränken. Die Lamelle 1 wird durch einen Luftstrom durch die unterhalb der Lamelle 1 angeordnete Auslassöffnungen (Fig. 1 : Bzz. 4) nach oben gebogen, bis sie in einem maximal geöffneten Zustand der Auslassöffnungen (Fig. 1 : Bzz. 4) an einer der Lamelle 1 zugewandten Abstützfläche 5 anliegt. Die Brücke 2 hat in einem Bereich eine Abstützfläche 5 mit einem vorbestimmten Krümmungsradius g, der im Wesentli- chen identisch zu dem in Fig. 2a gezeigten Krümmungsradius g ist, so dass einerseits eine möglichst große Auslassfläche realisiert wird, andererseits durch eine Vergröße- rung von Biegespannungen aber eine Lebensdauer nicht verringert wird. Ferner weist die Brücke 2 eine hier nicht dargestellte Vertiefung auf, durch die die La- melle 1 seitlich geführt wird, um ein seitliches Verschieben der Lamelle 1 einzuschrän- ken. Die Brücke 2 weist ferner Durchgangslöcher 8 für Befestigungselemente 3 auf. The embodiment of the Auslasslamellenventils according to the figures 3a and 3b, like the prior art according to Figures 1, 2a and 2b, also a lamella 1 for closing and opening of an outlet not shown here (Figure 1: Bzz. 4). It may be provided a single outlet opening or alternatively a plurality of outlet openings, wherein an entire cross-sectional area of the outlet openings should be chosen as large as possible in order to minimize a pressure loss during the expulsion of the air. The outlet louver valve also has a bridge 2 to restrict deformation of the lamella 1. The lamella 1 is bent upwards by an air flow through the outlet openings (FIG. 1: Bzz. 4) arranged below the lamella 1 until it is in a maximum open state of the outlet openings (FIG 1 facing support surface 5 is applied. The bridge 2 has in one area a supporting surface 5 with a predetermined radius of curvature g, which is essentially identical to the radius of curvature g shown in FIG. 2a, so that on the one hand the largest possible outlet area is realized, but on the other hand a lifetime is not reduced by an increase in bending stresses , Furthermore, the bridge 2 has a recess, not shown here, through which the lamella 1 is guided laterally in order to restrict lateral displacement of the lamella 1. The bridge 2 also has through holes 8 for fastening elements 3.
Die Befestigungselemente 3 bestehen hier jeweils aus Bolzen und Muttern, können aber auch in einer anderen Form, beispielsweise als Niete, ausgeführt sein. Wie in Fig. 3b gezeigt, weist die Lamelle 1 , im Gegensatz zu der Lamelle 1 im Stand der Technik (Fig. 1 , Fig. 2b), Öffnungen 6 auf, durch die Befestigungselemente 3 jeweils die Lamelle 1 durchdringen können, um die Brücke 2 an dem Gehäuse (Fig. 1 : Bzz. 9) des Kompressionszylinders zu befestigen. Dadurch ist es möglich, bei einem annä- hernd gleichen Krümmungsradius g der Lamelle, den Flub a (Fig. 2a) auf einen Hub a' zu vergrößern. The fasteners 3 here consist of bolts and nuts, but can also be in a different form, for example, as rivets executed. As shown in FIG. 3b, unlike the prior art blade 1 (FIGS. 1, 2b), the blade 1 has openings 6 through which fastening elements 3 can each penetrate the blade 1 around the bridge 2 to the housing (Fig. 1: Bzz. 9) of the compression cylinder. This makes it possible, with an approximately equal radius of curvature g of the lamella, to increase the flub a (FIG. 2 a) to a stroke a '.
Ferner ist es alternativ auch möglich, dass nur eine Öffnung 6 vorgesehen ist, wobei dann die Befestigungselemente 3 nur durch diese eine Öffnung 6 dringen. Alternativ be- steht auch die Möglichkeit, dass mehr als zwei Öffnungen 6 für die Befestigungsele- mente 3 vorgesehen sind. Fig. 4a zeigt eine isometrische Ansicht der Lamelle 1 und der Befestigungselemente 3 einer modifizierten ersten Ausführungsform der Erfindung. Die Öffnungen 6 sind hier nicht, wie in der in Fig. 3b gezeigten Ausführungsform, als auf eine Abmessung der Be- festigungselement 3 abgestimmte Durchgangslöcher gebildet, sondern weisen nachste- hend beschriebene Abmessungen auf. Fig. 4b zeigt eine Draufsicht auf eine alternative Lamelle 1 der modifizierten ersten Aus- führungsform der Erfindung. Die Öffnungen 6 sind in dieser Lamelle 1 zu den Enden in der Längsrichtung offen. Furthermore, it is alternatively also possible that only one opening 6 is provided, in which case the fastening elements 3 only penetrate through this opening 6. Alternatively, there is also the possibility that more than two openings 6 are provided for the fastening elements 3. FIG. 4a shows an isometric view of the lamella 1 and the fastening elements 3 of a modified first embodiment of the invention. The openings 6 are not formed here, as in the embodiment shown in FIG. 3 b, as through holes matched to a dimension of the fastening element 3, but have dimensions described below. 4b shows a plan view of an alternative lamella 1 of the modified first embodiment of the invention. The openings 6 are open in this lamella 1 to the ends in the longitudinal direction.
In Fig. 4c, einer isometrischen Schnittansicht der modifizierten ersten Ausführungsform der Erfindung, weist die Brücke 2 durchgehende Ausströmlöcher 7 mit vorbestimmten Abmessungen auf. Die Ausströmlöcher 7 sind jeweils in einem Bereich, der mit den Öff- nungen 6 der bestimmungsgemäß in der Brücke 2 angeordneten Lamelle 1 im Wesent- lichen übereinstimmt, vorgesehen. Die Abmessungen der Öffnungen 6 sind so gewählt, dass sie im Wesentlichen den vorbestimmten Abmessungen der zugehörigen Aus- strömlöcher 7 entsprechen. Die Brücke 2 weist die Ausströmlöcher 7 zusätzlich zu den Durchgangslöchern 8 für die Befestigungselemente 3 auf. In Fig. 4c, an isometric sectional view of the modified first embodiment of the invention, the bridge 2 has continuous discharge holes 7 with predetermined Dimensions on. The outflow holes 7 are provided in each case in a region which substantially coincides with the openings 6 of the lamella 1 arranged as intended in the bridge 2. The dimensions of the openings 6 are selected so that they substantially correspond to the predetermined dimensions of the associated outflow holes 7. The bridge 2 has the discharge holes 7 in addition to the through holes 8 for the fixing elements 3.
Fig. 5a ist eine Explosionsdarstellung des Auslasslamellenventils gemäß einer zweiten Ausführungsform der Erfindung. Im Gegensatz zu der ersten Ausführungsform weist die Lamelle 1 die Öffnung 6 nicht in einem Außenbereich der Lamelle 1 auf, sondern die Öffnung 6, durch die das Befestigungselement 3 die Lamelle 1 durchdringt, ist in einem zentralen Bereich angeordnet. Fig. 5a is an exploded view of the outlet louver valve according to a second embodiment of the invention. In contrast to the first embodiment, the lamella 1 does not have the opening 6 in an outer region of the lamella 1, but the opening 6, through which the fastening element 3 penetrates the lamella 1, is arranged in a central area.
Auch hier ist die Lamelle 1 zum Verschließen und Öffnen der Auslassöffnungen 4 vor- gesehen. Die Brücke 2 ist ebenfalls zum Einschränken der maximalen Verformung der Lamelle 1 in einem geöffneten Zustand der Auslassöffnungen 4 vorgesehen. Dafür weist die Brücke 2 auch hier die der Lamelle 1 zugewandte Abstützfläche 5 auf. Da die Öffnung 6 für das Befestigungselement 3 in der dem zentralen Bereich der Lamelle 1 angeordnet ist, werden die Brücke 2 und auch die Lamelle 1 hier in ihrem jeweils zent- ralen Bereich befestigt. Wie in Fig. 5b, einer seitlichen Ansicht der Brücke des Auslass- ventils gemäß der zweiten Ausführungsform, gezeigt ist, entspricht auch hier der Krüm- mungsradius g im Wesentlichen den in Fig. 2a und 3a gezeigten Krümmungsradien g, so dass auch hier eine Lebensdauer der Lamelle 1 durch eine Vergrößerung der Biege- spannungen nicht verringert wird. Here, too, the lamella 1 is provided for closing and opening the outlet openings 4. The bridge 2 is also provided for restricting the maximum deformation of the fin 1 in an opened state of the outlet openings 4. For this, the bridge 2 also here the the lamella 1 facing support surface 5. Since the opening 6 for the fastening element 3 is arranged in the central region of the lamella 1, the bridge 2 and also the lamella 1 are fastened here in their respectively central area. As shown in FIG. 5b, a side view of the bridge of the outlet valve according to the second embodiment, the radius of curvature g also corresponds substantially to the radii of curvature g shown in FIGS. 2a and 3a, so that here too a service life The lamella 1 is not reduced by an increase in the bending stresses.
Wie in Fig. 5a dargestellt, ist eine Verdrehsicherung zwischen der Lamelle 1 und dem Gehäuse 9 des Kompressionszylinders vorgesehen. Die Verdrehsicherung besteht aus drei Vertiefungen 10, die in dem Gehäuse 9 des Kompressionszylinders eingebracht sind. In der Lamelle 1 sind zu den Vertiefungen 10 komplementäre Einprägungen 11 vorgesehen, die somit nach unten vorstehen und in die Vertiefungen 10 eingreifen kön- nen, um eine Stellung der Lamelle 1 zu dem Gehäuse 9 sicherzustellen. Alternativ kön- nen in dem Gehäuse 9 auch Erhöhungen vorgesehen sein, wobei die Lamelle 1 dann zu den Erhöhungen komplementäre Einprägungen aufweist. Im Betrieb liegt die Lamelle 1 während eines Ansaugtakts des Kompressors über ein Einnehmen ihrer ursprünglichen Gestalt an der (den) Auslassöffnung(en) 4 an und wird durch einen Unterdrück in dem Kompressionszylinder an das Gehäuse 9 des Kompres- sionszylinders gesaugt, um die Auslassöffnung(en) 4 zu verschließen. Während eines Ausstoßtakts wird die Lamelle 1 durch die, aufgrund des Drucks in dem Kompressions- zylinder, ausströmende Luft von der (den) Auslassöffnungen 4 weggebogen, so dass die Luft ausströmen kann. Die Lamelle 1 wird soweit gebogen, bis sie an der Abstützflä- che 5 der Brücke 2 anliegt, wobei ein maximaler Krümmungsradius der Lamelle 1 fest- gelegt wird. Die Lamelle 1 hebt, bedingt durch die ausströmende Luft, von dem Ge- häuse 9 ab, um einen Verschleiß an ihren Rändern zu minimieren. Die Luft strömt seit lich durch Ausströmflächen ab. As shown in Fig. 5a, an anti-rotation between the blade 1 and the housing 9 of the compression cylinder is provided. The anti-rotation consists of three recesses 10, which are incorporated in the housing 9 of the compression cylinder. In the slat 1 complementary indentations 11 are provided to the recesses 10, thus projecting downwards and NEN can engage in the recesses NEN to ensure a position of the slat 1 to the housing 9. Alternatively, elevations can also be provided in the housing 9, the lamella 1 then having embossings complementary to the elevations. In operation, during an intake stroke of the compressor, the vane 1 rests against the outlet opening (s) 4 by taking its original shape and is sucked by a negative pressure in the compression cylinder to the housing 9 of the compression cylinder, around the outlet opening (FIG. en) 4 to close. During an exhaust stroke, the fin 1 is deflected away from the exhaust port (s) 4 by the air flowing out due to the pressure in the compression cylinder, so that the air can flow out. The lamella 1 is bent until it rests against the support surface 5 of the bridge 2, wherein a maximum radius of curvature of the lamella 1 is determined. Due to the outflowing air, the lamella 1 lifts off from the housing 9 in order to minimize wear at its edges. The air flows since Lich by Ausströmflächen.
Durch das erfindungsgemäße Auslasslamellenventil ist es möglich, den Hub a (Fig. 2a) der Lamelle 1 bei einem annähernd gleichen Krümmungsradius der Lamelle 1 auf den Hub a' (Fig. 3a) zu vergrößern, um einen Druckabfall an dem Auslasslamellenventil zu verringern. The outlet louver valve according to the invention makes it possible to increase the stroke a (FIG. 2a) of the lamella 1 at an approximately identical radius of curvature of the lamella 1 to the stroke a '(FIG. 3a) in order to reduce a pressure drop at the outlet lamella valve.
Bei einem optionalen Vorsehen des Ausströmlochs 7 oder der Ausströmlöcher 7 und vergrößerter Öffnungen 6 in der Lamelle 1 kann hier zusätzlich Luft aus den Auslassöff- nungen 4 ausströmen, wobei hier bauraumbedingt üblicherweise ein ungestörteres Aus- strömen als durch die seitlichen Ausströmflächen möglich ist. In der zweiten Ausführungsform der Erfindung kann die Luft aus den Auslassöffnungen 4 in einem annähernd um die Auslassöffnung 4 umlaufenden Bereich ausströmen, so dass der Druckabfall nochmals reduziert ist. In the case of an optional provision of the outflow hole 7 or the outflow holes 7 and enlarged openings 6 in the lamella 1, additional air can flow out of the outlet openings 4, whereby here, due to space constraints, an undisturbed outflow is usually possible than through the lateral outflow surfaces. In the second embodiment of the invention, the air can flow out of the outlet openings 4 in an area which circulates approximately around the outlet opening 4, so that the pressure drop is reduced again.
