Description

Die Erfindung betrifft ein motorisch betätigbares Druckventil für Kabinen von Eisenbahnwagen oder der­gleichen, insbesondere für Fahrgastkabinen von Reise­zugwagen.The invention relates to a motor-operated pressure valve for cabins of railroad cars or the like, in particular for passenger cabins of passenger cars.

Zugbegegnungen auf der Strecke ganz allgemein und Zugdurchfahrten in Tunneln führen besonders an den Tunnelein- bzw. Tunnelausfahrten und bei Zugbegeg­nungen im Tunnel zu hohen Schwankungen des Luftdrucks in der Umgebung der Kabine der Wagen des Zuges, so daß gegenüber dem Innendruck der Kabine ein er­heblicher Uberdruck oder auch ein entsprechend großer Unterdruck entsteht. Diese wellenförmig auftretende Druckschwankung setzt sich durch die relativ groß zu bemessenden Offnungen für die Zuluft und Fortluft der Belüftung in den Innenraum der Kabine fort und führt dementsprechend auch in der Kabine zu einem plötz­lichen Druckanstieg und/oder Druckabfall mit Wellencharakteristik. Solche Druckschwankungen in der Kabine stören die Insassen erheblich und beein­trächtigen die Steuerungen der Klimaanlagen von klimatisierten Kabinen für die Aufnahme von Personen und Frachtgut. Der Komfort moderner Reisezugwagen mit Klimaanlagen wird dadurch erheblich nachteilig beeinflußt. Diese Nachteile wachsen mit zunehmender Reisegeschwindigkeit moderner Züge oder zwingen zur Verringerung der Reisegeschwindigkeit bei Tunnel­durchfahrten oder Zugbegegnungen, insbesondere Zug­begegnungen im Tunnel.Train encounters on the route in general and train passages in tunnels lead to high fluctuations in the air pressure in the vicinity of the cabin of the train, particularly at the tunnel entrances and exits and during train encounters in the tunnel, so that a considerable overpressure or a correspondingly large negative pressure also arises. This wave-like pressure fluctuation continues through the relatively large openings for the supply air and exhaust air of the ventilation into the interior of the cabin and accordingly also leads to a sudden pressure increase and / or pressure drop in the cabin Wave characteristic. Such pressure fluctuations in the cabin considerably disturb the occupants and impair the controls of the air conditioning systems of air-conditioned cabins for the accommodation of people and freight. The comfort of modern passenger coaches with air conditioning is significantly adversely affected. These disadvantages grow with the increasing speed of travel of modern trains or force the reduction of the speed of travel when passing through tunnels or during train encounters, especially train encounters in tunnels.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Druckventil für Kabinen von Eisenbahnwagen zu ge­stalten, welches bei Erreichen einer vorbestimmbaren Druckdifferenz zwischen dem Inneren und dem Außeren der Kabine durch einen motorischen Antrieb in extrem kurzer Zeit große Querschnitte der Zuluft- und Fortluftöffnungen für die Belüftung der Kabine ver­schließt und welches seine einwandfreie Funktion auch bei hohen plötzlich auftretenden Druckdifferenzen beibehält.The invention is therefore based on the object to design a pressure valve for cabins of railroad cars, which when reaching a predeterminable pressure difference between the inside and the outside of the cabin by a motor drive in an extremely short time large cross-sections of the supply air and exhaust air openings for ventilation of the Cabin closes and which maintains its perfect function even with high sudden pressure differences.

Die Erfindung löst diese Aufgabe durch Ausbil­dungsmerkmale nach dem Kennzeichen des Patent­anspruches 1.The invention solves this problem by training features according to the characterizing part of patent claim 1.

Ein Druckventil mit diesen Ausbildungsmerkmalen ermöglicht extrem große Offnungsquerschnitte für den Luftstrom und kann mittels eines motorischen Ver­stellantriebes in ganz kurzer Zeit dicht geschlossen und voll geöffnet werden. Trotz der für die Er­reichung großer freier Strömungsquerschnitte bei geöffnetem Ventil erforderlichen Flächenausdehnung des Ventils läßt sich eine gute Steifigkeit erzielen, da die Führungsplatten die Ventilplatte von beiden Seiten aussteifen bzw. abstützen. Die Verwendung der Ventilplatte und deren Anordnung zwischen zwei Führungsplatten ermöglicht außerdem relativ breite Uberdeckungsflächen an den Rändern zur Abdichtung, so daß bei geschlossenem Druckventil hohe Dichtigkeit über längere Zeiträume erreicht und auch bei wellenförmigen Druckschwankungen mit hohem Uberdruck und hohem Unterdruck aufrechterhalten werden können. Dadurch lassen sich entsprechende Anforderungen für klimatisierte Kabinen von Reisezugwagen an geringe Leckagebeiwerte erfüllen. Die einwandfreie Funktion des Druckventils bleibt selbst dann erhalten, wenn die hohen Druckschwankungen schon während des Schließvorganges auftreten.A pressure valve with these training features enables extremely large opening cross sections for the air flow and can be tightly closed and fully opened in a very short time using a motorized adjustment drive. Despite the surface area required to achieve large free flow cross-sections with the valve open The valve can be stiff because the guide plates stiffen or support the valve plate from both sides. The use of the valve plate and its arrangement between two guide plates also enables relatively wide cover areas at the edges for sealing, so that high tightness can be achieved over long periods of time when the pressure valve is closed and can also be maintained in the case of undulating pressure fluctuations with high excess pressure and high negative pressure. This enables the corresponding requirements for air-conditioned cabins for passenger coaches to be met with low leakage coefficients. The proper functioning of the pressure valve is maintained even if the high pressure fluctuations occur during the closing process.

Bei einem bevorzugten Ausführungsbeispiel der Erfin­dung ist vorgesehen, daß die Ventilplatte zwischen den beiden Führungsplatten mit einem geringen Spiel quer zur Plattenebene angeordnet ist und daß die relativ zueinander beweglichen Führungsflächen der Ventilplatte und der beiden Führungsplatten sich mit einer Beschichtung aus einem begrenzt elastischen Werkstoff mit geringem Reibungsbeiwert berühren. Durch diese Ausbildung wird einerseits eine leichtgängige Beweglichkeit der Ventilplatte zwischen den beiden Führungsplatten und außerdem ein hohes Maß an Dichtigkeit erreicht. Für die Beschichtung eignet sich besonders handelsübliches Kunststoffmaterial, welches unter der Kurzbezeichnung PTFE handelsüblich ist. Dieser Werkstoff hat einen äußerst geringen Reibungsbeiwert und ist begrenzt elastisch, so daß er als Dichtungswerkstoff geeignet ist. Das geringe Spiel quer zur Plattenebene führt bei ausgeglichenem Druck zwischen dem Inneren und dem Außeren der Kabine zu einer praktisch reibungsfreien Bewegung der Ven­tilplatte, so daß geringe Antriebskräfte ausreichen, und andererseits wird dieses Spiel praktisch genutzt, so daß die Ventilplatte bei geschlossenen Druckventil sowohl durch einen inneren Uberdruck als auch durch einen äußeren Uberdruck mit diesem dichtenden Werkstoff fest gegen die jeweils stützende Füh­rungsplatte gepreßt wird. Trotzdem bleibt eine Bewegungsmöglichkeit der Ventilplatte selbst bei hohen Druckdifferenzen infolge des geringen Rei­bungsbeiwertes dieses Beschichtungswerkstoffes erhal­ten.In a preferred embodiment of the invention it is provided that the valve plate is arranged between the two guide plates with a little play transversely to the plane of the plate and that the guide surfaces of the valve plate and the two guide plates, which are movable relative to one another, are coated with a coating of a limited elastic material with a low coefficient of friction touch. With this design, on the one hand, smooth movement of the valve plate between the two guide plates and a high degree of tightness are achieved. Commercial plastic material, which is commercially available under the abbreviation PTFE, is particularly suitable for the coating. This material has an extremely low coefficient of friction and has limited elasticity, making it suitable as a sealing material. The minor Clearance across the plane of the plate leads to a practically frictionless movement of the valve plate with balanced pressure between the inside and the outside of the cabin, so that low driving forces are sufficient, and on the other hand this play is used practically so that the valve plate is closed by an internal overpressure when the pressure valve is closed as well as by an external overpressure with this sealing material is pressed firmly against the respective supporting guide plate. Nevertheless, the valve plate remains able to move even at high pressure differences due to the low coefficient of friction of this coating material.

Für die konstruktive Ausbildung des Druckventils ist nach einem weiteren Erfindungsgedanken vorgesehen, daß die Ventilplatte einen oder auch mehrere Zapfen aufweisen, die sich quer zur Ebene der Ventilplatte erstrecken und in Schlitze einer Führungsplatte ein­greifen, deren Länge den Weg der Bewegung der Ventilplatte gegenüber den Führungsplatten begrenzt. Mit einem dieser Zapfen oder auch mit mehreren der Zapfen kann der motorische Antrieb gelenkig verbunden sein, welcher vorteilhaft aus einer pneumatisch beaufschlagbaren Kolben-Zylinder-Einheit besteht. Diese Kolben-Zylinder-Einheit läßt sich in an sich bekannter Weise durch Sensoren steuern, die die Druckdifferenzen in Schaltimpulse für den motorischen Antrieb umsetzen. Die Druckdifferenzen, bei denen Schaltimpulse ausgelöst werden sollen, sind vorbestimmbar, wie es an sich ebenfalls bekannt ist.For the structural design of the pressure valve is provided according to a further inventive concept that the valve plate have one or more pins which extend transversely to the plane of the valve plate and engage in slots in a guide plate, the length of which limits the path of movement of the valve plate relative to the guide plates . The motor drive, which advantageously consists of a piston-cylinder unit which can be acted upon pneumatically, can be connected in an articulated manner to one of these pins or also to several of the pins. This piston-cylinder unit can be controlled in a manner known per se by sensors which convert the pressure differences into switching pulses for the motor drive. The pressure differences at which switching pulses are to be triggered can be predetermined, as is also known per se.

Auf der Zeichnung ist ein Ausführungsbeispiel der Er­findung dargestellt. Es zeigen:

  • Figur 1 eine Seitenansicht eines Druck­ventils,
  • Figur 2 einen Teilschnitt nach der Linie A - B der Figur 1 und
  • Figur 3 in einem gegenüber den Figuren 1 und 2 vergrößerten Maßstab einen Schnitt durch das eine Ende des Druckventils.
In the drawing, an embodiment of the invention is shown. Show it:
  • FIG. 1 shows a side view of a pressure valve,
  • 2 shows a partial section along the line A - B of Figure 1 and
  • 3 shows a section through one end of the pressure valve on an enlarged scale compared to FIGS.

Das in die Wand einer Fahrgastkabine eines Reisezug­wagens oder dergleichen einbaubare Druckventil be­steht aus der inneren Ventilplatte 1 und den beiden äußeren Führungsplatten 2 und 3, die die Ventilplatte 1 von beiden Seiten abstützen. In der Ventilplatte 1 sind in Abständen parallel zueinander verlaufende Schlitze 4 vorgesehen, und ebenso weisen die Führungsplatten 2 und 3 an sich überdeckenden Stellen zueinander parallel verlaufende Schlitze 5 und 6 auf, deren Breite etwa der Breite der Schlitze 4 ent­spricht. Die Breite der Stege zwischen den Schlitzen 4 der Ventilplatte 1 ist jedoch erheblich größer als die Breite der Schlitze 5 und 6 in den Füh­rungsplatten 2 und 3, so daß bei geschlossenem Druck­ventil, welches der Darstellung in den Zeichnungsfiguren entspricht, eine erhebliche Mate­rialüberdeckung zur Erzielung einer guten Dichtigkeit des Druckventils entsteht. Bei dem Ausführungs­beispiel ist die Ventilplatte 1 zwischen den Führungsplatten 2 in ihrer Ebene quer zur Längs­richtung der Schlitze 4,5 und 6 beweglich angeordnet, wobei ein Zapfen 7 oder auch mehrere Zapfen diese Bewegung der Ventilplatte 1 gegenüber den Füh­rungsplatten 2 und 3 begrenzt. Der Zapfen 7 ist auf der Ventilplatte 1 befestigt und erstreckt sich quer zur Ebene der Abdeckplatte 1 in ein Langloch 8, dessen Enden Anschläge für den Zapfen 7 bilden. Gleichzeitig ist dieser Zapfen 7 oder sind mehrere solcher Zapfen Angriffspunkte für den motorischen Antrieb zum Schließen und Offnen des Druckventils. Im Beispiel besteht dieser motorische Antrieb aus einer Kolben-Zylinder-Einheit, deren Kolbenstange 9 gelenkig mit dem Zapfen 7 verbunden ist und deren Zylinder 10 gegenüber der Führungsplatte 3 festgelegt ist. Die Sensorsteuerung für diesen motorischen Antrieb 9,10 wurde auf der Zeichnung nicht dar­gestellt und bildet auch nicht den Gegenstand der Erfindung.The pressure valve which can be built into the wall of a passenger cabin of a passenger car or the like consists of the inner valve plate 1 and the two outer guide plates 2 and 3, which support the valve plate 1 from both sides. In the valve plate 1 there are slots 4 running parallel to one another at intervals, and likewise the guide plates 2 and 3 have slots 5 and 6 running parallel to one another at overlapping locations, the width of which corresponds approximately to the width of the slots 4. The width of the webs between the slots 4 of the valve plate 1 is, however, considerably larger than the width of the slots 5 and 6 in the guide plates 2 and 3, so that when the pressure valve is closed, which corresponds to the illustration in the drawing figures, a considerable material coverage to achieve a good tightness of the pressure valve arises. In the embodiment, the valve plate 1 between the Guide plates 2 are arranged to be movable in their plane transverse to the longitudinal direction of the slots 4, 5 and 6, a pin 7 or a plurality of pins limiting this movement of the valve plate 1 relative to the guide plates 2 and 3. The pin 7 is fastened on the valve plate 1 and extends transversely to the plane of the cover plate 1 into an elongated hole 8, the ends of which form stops for the pin 7. At the same time, this pin 7 or several such pins are points of attack for the motor drive for closing and opening the pressure valve. In the example, this motor drive consists of a piston-cylinder unit, the piston rod 9 of which is articulated to the pin 7 and the cylinder 10 of which is fixed relative to the guide plate 3. The sensor control for this motor drive 9, 10 was not shown in the drawing and does not form the subject of the invention.

Die Besonderheit der Erfindung, daß die Ventilplatte 1 mit einem geringen Spiel quer zur Plattenebene zwischen den beiden Führungsplatten 2 und 3 dargestellt ist, ergibt sich aus den Zeichnungs­figuren 2 und 3. Zur Erzielung hoher Dichtigkeits­werte und einer leichten Verstellmöglichkeit der Ventilplatte 1 auch bei Druckdifferenzen sind die Anlageflächen der Führungsplatten 2 und 3 für die Ventilplatte 1 mit einem Kunststoff beschichtet, der einen geringen Reibungsbeiwert aufweist und begrenzt materialelastisch ist. Diese Beschichtungen 11 sind in der Figur 3 bezeichnet und in der Figur 2 an den etwas dickeren Linien zu erkennen.The peculiarity of the invention that the valve plate 1 is shown with a slight play transversely to the plane of the plate between the two guide plates 2 and 3 results from the drawing figures 2 and 3. To achieve high tightness values and an easy adjustment of the valve plate 1 are also at pressure differences the contact surfaces of the guide plates 2 and 3 for the valve plate 1 are coated with a plastic which has a low coefficient of friction and is of limited elasticity. These coatings 11 are designated in FIG. 3 and can be recognized in FIG. 2 by the somewhat thicker lines.

Zur Sicherung der Einhaltung äußerst geringer Leckagebeiwerte, wie sie weiter oben bereits erwähnt wurden, kann die beschriebene Konstruktion des Druckventils auch dupliziert werden, so daß mehrere Ventilplatten 1 parallel nebeneinander zwischen je zwei Führungsplatten 2 beweglich angeordnet sind. Dadurch entsteht bei geschlossenem Druckventil eine Mehrfachdichtung mit einem Labyrinth an jedem einzelnen Durchgangsschlitz 4 der Ventilplatten.To ensure compliance with extremely low leakage coefficients, as already mentioned above, the described construction of the pressure valve can also be duplicated, so that a plurality of valve plates 1 are arranged in parallel next to each other between two guide plates 2. This creates a multiple seal with a labyrinth at each individual through slot 4 of the valve plates when the pressure valve is closed.
