Description

Die Erfindung betrifft eine Ventilplatte mit einem Kühlmittelkanal für einen Kompressor zur Drucklufterzeugung gemäß dem Oberbegriff von Anspruch 1.The invention relates to a valve plate with a coolant channel for a compressor for compressed air generation according to the preamble of claim 1.

Die Erfindung betrifft weiterhin ein Verfahren zur Kühlung von komprimierter Luft in einem Kompressor mit einer solchen Ventilplatte.The invention further relates to a method for cooling compressed air in a compressor with such a valve plate.

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 die Luft stark erwärmt. Diese Erwärmung wächst mit steigendem Förderdruck 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 Trocknungsmittel, das nur bis maximal 80 °C der Luft Feuchtigkeit entziehen kann. Daher wird normalerweise eine geringere maximal zulässige Temperatur von 60 °C angegeben, um eine effektive Trocknung zu ermöglichen. Bei der Komprimierung im Kompressor erreicht die komprimierte Luft an der Austrittsöffnung des Kolbenraumes jedoch Temperaturen von bis zu 320 °C. Am Ausgang des Kompressors selbst dürfen es maximal noch 220 °C 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 Durchströmens der Druckleitung vom Kompressor zur Luftfilterpatrone ohne weitere Kühlmaßnahmen abkühlen kann. Nachteilig hierbei ist der Druckverlust durch die lange Leitung und der bauliche Aufwand den die Druckleitung selbst verursacht.Compressing the air in the compressor greatly heats the air. This heating increases with increasing delivery 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 desiccant that can extract moisture from the air only up to 80 ° C. Therefore, a lower maximum allowable temperature of 60 ° C is usually specified to allow effective drying. When compressed in the compressor, however, the compressed air at the outlet opening of the piston chamber reaches temperatures of up to 320 ° C. At the outlet of the compressor itself, the maximum temperature may be 220 ° C. This results in the need to cool the air between the compressor and the air filter cartridge. For this purpose, a pressure line of several meters in length is used in the prior art, wherein the heated compressed air can cool during flow through the pressure line from the compressor to the air filter cartridge without further cooling measures. The disadvantage here is the pressure loss caused by the long line and the structural complexity of the pressure line itself.

Um die lange Druckleitung zwischen Kompressor und Filterpatrone verkürzen zu können, ist es notwendig, die Druckluft 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 °C am Kompressorausgang zu senken und die anschließende Druckleitung um 5 bis 30 % zu verkürzen. Ein Beispiel für eine solche Supercooling-Platte ist in der DE 195 35 079 C2 zu finden.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 ° C at the compressor outlet and the subsequent pressure line to shorten by 5 to 30%. An example of such a supercooling plate is in the DE 195 35 079 C2 to find.

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.

Die US 2007/0081910 A1 beschreibt ein Kühlsystem mit einem Kompressor, der ein Ansaugventil umfasst, wobei in dem Boden des Ansaugventilsitzes eine spiralförmige Nut vorgesehen ist, um eine Dichtwirkung nach dem Prinzip einer Labyrinthdichtung zu erzielen.The US 2007/0081910 A1 describes a cooling system with a compressor comprising a suction valve, wherein in the bottom of Ansaugventilsitzes a spiral groove is provided to achieve a sealing effect on the principle of a labyrinth seal.

Die US 3,823,735 A beschreibt eine spezielle Bauform eines Rückschlagventils, das als Lufteinlass- oder Luftauslassventil eines Kompressors verwendet werden kann.The US 3,823,735 A describes a special design of a check valve that can be used as an air inlet or outlet valve of a compressor.

Die US 2004/0086406 A1 beschreibt einen Zylinderkopf eines Kompressors mit mehreren Kammern, die von dem von dem Kompressor geförderten Kühlmittel nacheinander durchströmt werden, um Pulsationen zu dämpfen.The US 2004/0086406 A1 describes a cylinder head of a compressor having a plurality of chambers, which are successively flowed through by the coolant conveyed by the compressor in order to damp pulsations.

Die DE 866 712 A beschreibt eine Ventilplatte wobei die zu komprimierende Luft als Kühlmittel verwendet wird. Kühlmitteleinlass und Kühlmittelauslass sind in DE 866 712 A daher gleich Lufteinlass und Luftauslass.The DE 866 712 A describes a valve plate wherein the air to be compressed is used as the coolant. Coolant inlet and coolant outlet are in DE 866 712 A therefore equal to the air inlet and outlet.

Der Erfindung liegt die Aufgabe zugrunde, eine Ventilplatte bereitzustellen, die ohne eine Supercooling-Platte eine im Vergleich mit einer Kombination einer herkömmlichen Ventilplatte und einer Supercooling-Platte zumindest gleiche Kühlleistung erbringt.The invention has for its object to provide a valve plate without a supercooling plate at least equal cooling performance compared to 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.

Bei der erfindungsgemäßen Ventilplatte ist vorgesehen, dass der Kühlmittelkanal von einem Kolbenraum 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 Kolbenraum senkrecht auf die Ventilplatte zeigt, ist es noch möglich, dass der Kühlmittelkanal zumindest teilweise vor dem Luftauslassventil verläuft.In the case of the valve plate according to the invention, it is provided that, viewed from a piston chamber of the compressor, the coolant channel 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 increases the achievable cooling capacity. The heated compressed air is therefore already cooled from reaching the air outlet valve of the present in the coolant passage coolant. In particular, when the viewing direction of the piston chamber is perpendicular to the valve plate, it is still possible that the coolant channel extends at least partially in front of the air outlet valve.

Dabei ist vorgesehen, dass der Kühlmittelkanal mäanderförmig in dem Boden der Ventilplatte verläuft. Durch den mäanderförmigen Verlauf des Kühlmittelkanals in dem Boden der Ventilplatte wird die Kontaktfläche des Kühlmittelkanals mit der Ventilplatte erhöht, wodurch eine höhere Kühlleistung bereitgestellt werden kann.It is provided that the coolant channel runs meandering in the 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 increases with the valve plate, whereby a higher cooling capacity can be provided.

Die erfindungsgemäße Ventilplatte baut auf der gattungsgemäßen Ventilplatte dadurch auf, dass der Kühlmittelkanal von einem Kolbenraum des Kompressors aus gesehen zumindest teilweise zwischen dem Kolbenraum und einem in der Ventilplatte angeordneten Luftauslassventil verläuft.The valve plate according to the invention builds on the generic valve plate in that the coolant channel, viewed from a piston chamber of the compressor, extends at least partially between the piston chamber and an air outlet valve arranged in the valve plate.

Dabei kann auch vorgesehen sein, dass eine Luftführung mäanderförmig in dem 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 meander-shaped in the 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 zwei Luftauslassventile in dem Körper der Ventilplatte angeordnet sind. Die gleichzeitige Verwendung mehrerer Luftauslassventile reduziert Drosselverluste, die durch einen begrenzten Ventilquerschnitt verursacht werden. In diesem Zusammenhang wird auch die Wärmeentwicklung an den Luftauslassventilen reduziert.Preferably, it is also provided that two air outlet valves are arranged in the body of the valve plate. The simultaneous use of multiple air outlet valves reduces throttling losses caused by a limited valve cross-section. In this context, the heat development is reduced at the air outlet valves.

Die Erfindung betrifft weiterhin einen Kompressor mit einer erfindungsgemäßen Ventilplatte.The invention further relates to a compressor with a valve plate according to the invention.

Das gattungsgemäße Verfahren wird dadurch weiterentwickelt, 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 erfindungsgemäßen 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 in that the coolant is viewed from a piston chamber of a compressor at least partially passed between the piston chamber and an arranged in the valve plate air outlet along. In this way, the advantages and particularities of the valve plate according to the invention 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.

Es ist vorgesehen, dass das Kühlmittel mäanderförmig in einem Boden der Ventilplatte geleitet wird.It is envisaged that the coolant is passed meandering in a bottom of the valve plate.

Vorzugsweise ist weiterhin vorgesehen, dass die komprimierte Luft mäanderförmig in einem Körper der Ventilplatte geleitet wird.Preferably, it is further provided that the compressed air is conducted meandering in a body of the valve plate.

Weiterhin ist vorgesehen, dass die komprimierte Luft durch zwei Luftauslassventile in einen Körper der Ventilplatte einströmt.It is further provided that the compressed air flows through two air outlet valves in a body of the valve plate.

Die Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand besonders bevorzugter Ausführungsformen beispielhaft erläutert.The invention will now be described by way of example with reference to the accompanying drawings by way of particularly preferred embodiments.

Weiterhin umströmt der Kühlmittelkanal 20 zwei Kolbenraumluftauslässe 48 die zu den hier nicht dargestellten Luftauslassventilen 22, 24 gehören. Die in dem Kühlmittelkanal 20 eingezeichneten Pfeile stellen eine beispielhafte Strömungsrichtung 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 Kühlmittelkanal 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.

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 Luftauslass 38. Weiterhin sind in dem Körper 30 ein Kühlmitteleinlass 42 und ein Kühlmittelauslass 44 eingezeichnet, über den das Kühlmittel durch den in Figur 3 dargestellten Kühlmittelkanal 20 zirkulieren kann. FIG. 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 hole 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 through the in FIG. 3 shown coolant channel 20 can circulate.
