Description

Ventilplatte für einen Kompressor und Verfahren zur Kühlung komprimierter Luft in einer Valve plate for a compressor and method for cooling compressed air in one
Ventilplatte eines KompressorsValve plate of a compressor
Die Erfindung betrifft eine Ventilplatte mit einem Kühlmittelkanal für einen Kompressor zur Drucklufterzeugung.The invention relates to a valve plate with a coolant channel for a compressor for compressed air generation.
Die Erfindung betrifft weiterhin ein Verfahren zur Kühlung von komprimierter Luft in einer Ventilplatte eines Kompressors, wobei die Ventilplatte einen Kühlmittelkanal umfasst .The invention further relates to a method for cooling compressed air in a valve plate of a compressor, wherein the valve plate comprises a coolant channel.
Moderne Nutzfahrzeuge, die im Schienen- oder Straßenverkehr eingesetzt werden, werden mit vielen Druckluft verbrauchenden Teilsystemen ausgerüstet. Zu diesen Teilsystemen gehört beispielsweise eine mit Druckluft betriebene Betriebsbremse und eine Luftfederung. Die Versorgung dieser Druckluftverbraucher mit Druckluft wird mit Hilfe einer Druckluftversorgungseinrichtung realisiert, die einen Kompressor umfasst . Umgebungsluft wird von dem Kompressor angesaugt, komprimiert und vor der Verwendung in den Verbrauchern von Fremdbestandteilen, wie Öl und Wasser, in weiteren Bestandteilen der Druckluftversorgungseinrichtung gereinigt .Modern commercial vehicles, which are used in rail or road traffic, are equipped with many compressed air consuming subsystems. These subsystems include, for example, a service brake operated by compressed air and air suspension. The supply of compressed air consumers with compressed air is realized by means of a compressed air supply device comprising a compressor. Ambient air is drawn in by the compressor, compressed and purified in other components of the compressed air supply device prior to use in the consumers of foreign matter such as oil and water.
Bei der Komprimierung der Luft in dem Kompressor wird dieWhen compressing the air in the compressor, the
Luft stark erwärmt . Diese Erwärmung wächst mit steigendem Fδrderdruck und steigender Umdrehungszahl des Kompressors an. Dies ist hinsichtlich der weiteren Aufbereitung der Druckluft, insbesondere der Lufttrocknung, nachteilig. Üblicherweise wird der Luft die Luftfeuchtigkeit in einer dem Kompressor nachgeschalteten Luftfilterpatrone entzogen. Diese Luftfilterpatrone enthält ein Trocknungsmit- tel, das nur bis maximal 80 0C der Luft Feuchtigkeit entziehen kann. Daher wird normalerweise eine geringere maximal zulässige Temperatur von 60 0C angegeben, um eine effektive Trocknung zu ermöglichen. Bei der Komprimierung im Kompressor erreicht die komprimierte Luft an der Aus- trittsöffnung des Kolbenraumes jedoch Temperaturen von bis zu 320 0C. Am Ausgang des Kompressors selbst dürfen es maximal noch 220 0C sein. Hieraus ergibt sich die Notwendigkeit, die Luft zwischen dem Kompressor und der Luftfilterpatrone abkühlen zu müssen. Zu diesem Zweck wird bei dem Stand der Technik eine Druckleitung mit mehreren Metern Länge verwendet, wobei sich die erhitzte Druckluft während des Durchstrδmens der Druckleitung vom Kompressor zur Luftfilterpatrone ohne weitere Kühlmaßnahmen abkühlen kann. Nachteilig hierbei ist der Druckver- lust durch die lange Leitung und der bauliche Aufwand den die Druckleitung selbst verursacht.Air strongly heated. This heating increases with increasing spring pressure and increasing number of revolutions of the compressor. This is in terms of further treatment of Compressed air, especially air drying, disadvantageous. Usually, the air is deprived of the humidity in an air filter cartridge downstream of the compressor. This air filter cartridge contains a drying agent that can extract moisture from the air only up to a maximum of 80 ° C. Therefore, a lower maximum allowable temperature of 60 ° C. is normally specified to allow effective drying. However, during the compression in the compressor, the compressed air reaches at the initial opening of the piston chamber temperatures of up to 320 0 C. At the output of the compressor itself, there can be up to even 220 0 C. This results in the need to cool the air between the compressor and the air filter cartridge. For this purpose, a pressure line with several meters in length is used in the prior art, wherein the heated compressed air can cool during the passage of the pressure line from the compressor to the air filter cartridge without further cooling measures. The disadvantage here is the pressure loss due to the long line and the structural complexity caused by the pressure line itself.
Um die lange Druckleitung zwischen Kompressor und Filterpatrone verkürzen zu können, ist es notwendig, die Druck- luft durch eine aktive Kühlung zu kühlen. Zu diesem Zweck wird in dem Zylinderkopf des Kompressors oberhalb der Ventilplatte eine so genannte Supercooling-Platte eingefügt, die von einem Kühlmittel durchströmt wird und als Wärmetauscher fungiert. Durch sie ist es möglich, die Austrittstemperatur der Druckluft auf 140 bis 150 0C am Kompressorausgang zu senken und die anschließende Druck- leitung um 5 bis 30 % zu verkürzen. Ein Beispiel für eine solche Supercooling-Platte ist in der DE 195 35 079 C2 zu finden.In order to be able to shorten the long pressure line between the compressor and the filter cartridge, it is necessary to cool the compressed air by active cooling. For this purpose, a so-called supercooling plate is inserted in the cylinder head of the compressor above the valve plate, which is flowed through by a coolant and acts as a heat exchanger. Through them it is possible to reduce the outlet temperature of the compressed air to 140 to 150 0 C at the compressor outlet and the subsequent pressure shortening the line by 5 to 30%. An example of such a supercooling plate can be found in DE 195 35 079 C2.
Nachteilig hierbei ist insbesondere die aufwendige Bauweise die sich durch die Integration der Supercooling- Platte als separates Bauteil in den Zylinderkopf des Kompressors ergibt, da hierdurch zusätzliche Abdichtungen notwendig werden.The disadvantage here is in particular the complex construction resulting from the integration of the supercooling plate as a separate component in the cylinder head of the compressor, as this additional seals are necessary.
Der Erfindung liegt die Aufgabe zugrunde, eine Ventil - platte bereitzustellen, die ohne eine Supercooling-Platte eine im Vergleich mit einer Kombination einer herkömmlichen Ventilplatte und einer Supercooling-Platte zumindest gleiche Kühlleistung erbringt.The object of the invention is to provide a valve plate which, without a supercooling plate, provides at least the same cooling performance in comparison with a combination of a conventional valve plate and a supercooling plate.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst .This object is solved by the features of the independent claims.
Vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.Advantageous embodiments and further developments emerge from the dependent claims.
Die Erfindung baut auf der gattungsgemäßen Ventilplatte dadurch auf, dass der Kühlmittelkanal von einem Kolben- räum des Kompressors aus gesehen zumindest teilweise zwischen dem Kolbenraum und einem in der Ventilplatte angeordneten Luftauslassventil verläuft . Durch diesen Verlauf des Kühlmittelkanals ist die gesamte Ventilplatte gleichmäßig kühlbar, wobei insbesondere im Bereich des Luftauslassventils die Temperatur der Ventilplatte gesenkt werden kann, was konsequenter Weise die erreichbare Kühlleistung erhöht. Die erhitzte Komprimierte Luft wird daher bereits ab dem Erreichen des Luftauslassventils von dem in dem Kühlmittelkanal vorhandenen Kühlmittel gekühlt. Insbesondere wenn die Blickrichtung von dem KoI- benraum senkrecht auf die Ventilplatte zeigt, ist es noch möglich, dass der Kühlmittelkanal zumindest teilweise vor dem Luftauslassventil verläuft .The invention builds on the generic valve plate by the fact that the coolant channel, as seen from a piston chamber of the compressor, runs at least partially between the piston chamber and an air outlet valve arranged in the valve plate. Through this course of the coolant channel, the entire valve plate is evenly cooled, in particular in the region of the air outlet valve, the temperature of the valve plate can be lowered, which consequently the achievable Cooling capacity increased. The heated compressed air is therefore already cooled from reaching the air outlet valve of the present in the coolant passage coolant. In particular, if the viewing direction of the piston chamber is perpendicular to the valve plate, it is still possible for the coolant channel to extend at least partially in front of the air outlet valve.
Nützlicherweise ist dabei vorgesehen, dass der Kühlmit- telkanal zumindest teilweise mäanderförmig in einem Boden der Ventilplatte verläuft . Durch den mäanderfδrmigen Verlauf des Kühlmittelkanals in dem Boden der Ventilplatte wird die Kontaktfläche des Kühlmittelkanals mit der Ventilplatte erhöht, wodurch eine höhere Kühlleistung bereitgestellt werden kann.Usefully, it is provided that the coolant channel runs at least partially meander-shaped in a bottom of the valve plate. Due to the meandering course of the coolant channel in the bottom of the valve plate, the contact surface of the coolant channel is increased with the valve plate, whereby a higher cooling capacity can be provided.
Dabei kann auch vorgesehen sein, dass eine Luftführung mäanderförmig in einem Körper der Ventilplatte verläuft. Auch der mäanderförmige Verlauf der Luftführung erhöht die erreichbare Kühlleistung, da die Kontaktoberfläche des zu kühlenden Mediums mit der gekühlten Ventilplatte erhöht wird.It can also be provided that an air duct runs meandering in a body of the valve plate. The meandering course of the air duct increases the achievable cooling capacity, since the contact surface of the medium to be cooled is increased with the cooled valve plate.
Vorzugsweise ist auch vorgesehen, dass mehrere Luftaus- lassventile in einem Körper der Ventilplatte angeordnet sind. Die gleichzeitige Verwendung mehrerer Luftauslass- ventile reduziert Drosselverluste, die durch einen begrenzten Ventilquerschnitt verursacht werden. In diesem Zusammenhang wird auch die Wärmeentwicklung an den Luft- auslassventilen reduziert. Die Erfindung betrifft weiterhin einen Kompressor mit einer erfindungsgemäßen Ventilplatte.Preferably, it is also provided that a plurality of air outlet valves are arranged in a body of the valve plate. The simultaneous use of several air outlet valves reduces throttling losses caused by a limited valve cross-section. In this context, the heat development at the air outlet valves is also reduced. The invention further relates to a compressor with a valve plate according to the invention.
Das gattungsgemäße Verfahren wird dadurch weiterentwi- ekelt, dass das Kühlmittel von einem Kolbenraum eines Kompressors aus gesehen zumindest teilweise zwischen dem Kolbenraum und einem in der Ventilplatte angeordneten Luftauslassventil entlang geleitet wird. Auf diese Weise werden die Vorteile und Besonderheiten der erfindungsge- mäßen Ventilplatte auch im Rahmen eines Verfahrens umgesetzt. Dies gilt auch für die nachfolgend angegebenen besonders bevorzugten Ausführungsformen des erfindungsgemäßen Verfahrens.The generic method is further developed by the refrigerant being directed at least partially between the piston chamber and an air outlet valve arranged in the valve plate, viewed from a piston chamber of a compressor. In this way, the advantages and peculiarities of the inventive valve plate are also implemented in the context of a method. This also applies to the following particularly preferred embodiments of the method according to the invention.
Dieses ist in nützlicher Weise dadurch weitergebildet, dass das Kühlmittel mäanderförmig in einem Boden der Ventilplatte geleitet wird.This is usefully further developed in that the coolant is passed meandering in a bottom of the valve plate.
Vorzugsweise ist weiterhin vorgesehen, dass die kompri- mierte Luft mäanderförmig in einem Körper der Ventilplatte geleitet wird.Preferably, it is further provided that the compressed air is passed meander-shaped in a body of the valve plate.
Weiterhin kann vorgesehen sein, dass die komprimierte Luft durch mehrere Luftauslassventile in einen Körper der Ventilplatte einströmt.Furthermore, it can be provided that the compressed air flows through a plurality of air outlet valves in a body of the valve plate.

10 umfasst von unten nach oben einen Boden 28, einen Körper 30, eine Dichtung 32 und einen Deckel 34. Der Deckel 34 und der Körper 30 werden durch die Dichtung 32 dicht miteinander verbunden, während der Körper 30 und der Boden 28 durch Löten oder Kleben dicht miteinander verbunden werden. Das Anbringen einer Dichtung zwischen dem Boden 28 und dem Körper 30 ist jedoch auch denkbar. In den Boden 28 ist ein Kühlmittelkanal 20 eingelassen, der mäanderfδrmig innerhalb des Bodens 28 verläuft. Nach oben hin wird der Kühlmittelkanal 20 von dem Körper 30 begrenzt. Weiterhin ist ein Lufteinlassventil 36 im zentralen Bereich des Bodens 28 sichtbar. In dem Körper 30 sind zwei Luftauslassventile 22, 24 angeordnet über die die komprimierte Luft in die Ventilplatte 10 strömt. Der Kühlmittelkanal 20 verdeckt dabei, vom Boden 28 zum Kδr- per 30 aus betrachtet, einen Teil der Luftauslassventile 22, 24. Durch einen Luftauslass 38 in dem Deckel 34 der Ventilplatte 10 kann die komprimierte Luft die Ventil- platte 10 schließlich wieder verlassen.10 includes a bottom 28, a bottom up Body 30, a seal 32 and a lid 34. The lid 34 and the body 30 are sealed together by the seal 32, while the body 30 and the bottom 28 are sealed together by soldering or gluing. However, the attachment of a seal between the bottom 28 and the body 30 is also conceivable. In the bottom 28, a coolant channel 20 is inserted, which extends meandering within the bottom 28. Towards the top, the coolant channel 20 is delimited by the body 30. Furthermore, an air inlet valve 36 in the central region of the bottom 28 is visible. In the body 30, two air outlet valves 22, 24 are arranged, via which the compressed air flows into the valve plate 10. The coolant channel 20 conceals a portion of the air outlet valves 22, 24, viewed from the floor 28 to the body 30. The compressed air can finally leave the valve plate 10 again through an air outlet 38 in the cover 34 of the valve plate 10.
Figur 3 zeigt eine Draufsicht auf einen Boden einer erfindungsgemäßen Ventilplatte. Der dargestellte Boden 28 mit dem mäanderförmig verlaufenden Kühlmittelkanal 20 weist mehrere Bohrungen auf, durch die Luft durch den Boden 28 hindurch treten kann. Im zentralen Bereich ist ein Lufteinlass 46 angeordnet, der zu dem hier nicht dargestellten Lufteinlassventil 36 gehört. Weiterhin umströmt der Kühlmittelkanal 20 zwei Kolbenraumluftauslässe 48 die zu den hier nicht dargestellten Luftauslass- ventilen 22, 24 gehören. Die in dem Kühlmittelkanal 20 eingezeichneten Pfeile stellen eine beispielhafte Strδ- mungsrichtung des Kühlmittels innerhalb des Bodens 28 dar. Die Kolbenraumluftauslässe 48 bilden zusammen mit hier nicht dargestellten Membranen die Luftauslassventile 22, 24, wobei die Membranen wie aus Figur 2 ersichtlich von dem Kolbenraum 40 aus gesehen teilweise von dem Kühl- mittelkanal 20 verdeckt werden. Dies gilt insbesondere auch, wenn die Blickrichtung senkrecht zur Ebene der Ventilplatte liegt.FIG. 3 shows a plan view of a bottom of a valve plate according to the invention. The illustrated bottom 28 with the meandering coolant channel 20 has a plurality of holes through which air can pass through the bottom 28. In the central area an air inlet 46 is arranged, which belongs to the air inlet valve 36, not shown here. Furthermore, the coolant channel 20 flows around two piston chamber air outlets 48, which belong to the air outlet valves 22, 24 (not shown here). The arrows drawn in the coolant channel 20 represent an exemplary direction of flow of the coolant within the bottom 28 The piston chamber air outlets 48, together with membranes, not shown here, form the air outlet valves 22, 24, the membranes being partially obscured by the coolant channel 20, as can be seen from FIG. 2, viewed from the piston chamber 40. This is especially true when the line of sight is perpendicular to the plane of the valve plate.
Figur 4 zeigt eine Draufsicht auf einen Körper einer erfindungsgemäßen Ventilplatte. Der dargestellte Körper 30 weist eine Luftführung 12 auf, in der die durch die Kolbenraumluftauslässe 48 einströmende Luft zu einem Luftauslass 38 geführt wird. Die Kolbenraumluftauslässe 48 sind, genau wie der Lufteinlass 46, Bohrungen durch den Körper 30. Der Luftauslass 38 hingegen ist keine Bohrung in dem Körper 30 sondern als Bohrung in dem hier nicht dargestellten Deckel 34 der Ventilplatte vorhanden. Die Luftführung 12 dient der Führung der komprimierten Luft von den Kolbenraumluftauslässen 48 zu dem Luftaus- lass 38. Weiterhin sind in dem Körper 30 ein Kühlmittel- einlass 42 und ein Kühlmittelauslass 44 eingezeichnet, über den das Kühlmittel durch den in Figur 3 dargestellten Kühlmittelkanal 20 zirkulieren kann.Figure 4 shows a plan view of a body of a valve plate according to the invention. The illustrated body 30 has an air guide 12 in which the air flowing in through the piston chamber air outlets 48 is directed to an air outlet 38. The Kolbenraumluftauslässe 48 are, as well as the air inlet 46, holes through the body 30. The air outlet 38, however, is no hole in the body 30 but as a bore in the cover 34, not shown here, the valve plate available. The air guide 12 serves to guide the compressed air from the Kolbenraumluftauslässen 48 to the air outlet 38. Furthermore, in the body 30, a coolant inlet 42 and a coolant outlet 44 are shown, through which the coolant circulate through the coolant passage 20 shown in Figure 3 can.
