Abstract

The invention relates to a hollow valve plate (1) of a piston compressor for liquid-cooled lamellar valves, comprising a single half shell (3) having cooling channels (4) open on the cylinder side and covered by a preferably welded or glued lamellar plate (2) at least along the cooling channels (4), comprising one suction blade (6) machined and joined as a single part in the area of each of the suction openings (5). The production and assembly is thereby simplified and the clearance is reduced.

Description

Hohle Ventilplatte  Hollow valve plate
Die Erfindung betrifft eine hohle Ventilplatte für flüssigkeitsgekühlte Lamellenventile eines Kolbenkompressors.  The invention relates to a hollow valve plate for liquid-cooled multi-valve valves of a reciprocating compressor.
Speziell bei Verwendung als Bremsluftverdichter in Kraftfahrzeugen oder ähnlichen, oft lange Zeit mit hoher Leistung laufenden Anwendungen ist es notwendig, die auf der Zylinderseite zumindest eine Sauglamelle und auf der Zylinderkopfseite zumindest eine Drucklamelle tragende Ventilplatte aktiv zu kühlen, um Überhitzungen in diesem Bereich zu vermeiden und auch um die über die Druckventile ausgeschobene verdichtete Luft zumindest zu einem gewissen Grad vorzukühlen, bevor sie dann zumeist im Zylinderkopfbereich vor dem Austritt weiter gekühlt wird. Es werden dafür nach dem Stande der Technik bereichsweise hohle bzw. mit Kühlkanälen versehene Ventilplatten eingesetzt, deren Kühlräume bzw. -kanäle an eine Flüssigkeitskühlung des Kolbenkompressors bzw. auch zusammen mit diesem an die Flüssigkeitskühlung einer zum Fahrzeugantrieb eingesetzten Brennkraftmaschine angeschlossen sind.  Especially when used as a brake air compressor in motor vehicles or similar, often long time high-performance applications, it is necessary to actively cool on the cylinder side at least one suction plate and on the cylinder head side bearing at least one pressure plate valve plate to avoid overheating in this area and also to pre-cool the compressed air which has been pushed out via the pressure valves, at least to a certain extent, before it is then generally further cooled in the cylinder head region before it leaves the outlet. For this purpose, according to the state of the art, partially hollow or with cooling channels provided valve plates are used, the cooling chambers or channels are connected to a liquid cooling of the reciprocating compressor or together with this to the liquid cooling of an internal combustion engine used for vehicle propulsion.
Heutiger Stand der Technik zum Herstellen derartiger hohler Ventilplatten ist üblicherweise das Löten. Dabei bestehen die zu verlötenden Einzelteile entweder aus einer Anzahl von dünnen gestanzten Stahlplatten, welche in Paketen zu einer Einheit verbunden werden, wobei aus mäanderförmigen Aussparungen und bereichsweisen Ausnehmungen der mittleren Platten zusammen mit den bis auf Zu- und Ableitöffnungen geschlossenen äußeren Platten Kühlkanäle bzw. -räume entstehen. Andererseits gibt es aber auch Ausführungen mit zwei einseitig offene Kanäle bzw. Bereiche aufweisenden Halbschalen (zumeist aus Grauguss), die beim Zusammenbau dann im Inneren geschlossene dreidimensionale Kanäle bzw. Räume bilden. Bei beiden Ausführungsvarianten werden die Sauglamellen und Drucklamellen separat abschließend über Steckhülsen oder ähnliches auf der Ventilplatte befestigt. Today's state of the art for producing such hollow valve plates is usually soldering. The individual parts to be soldered consist either of a number of thin stamped steel plates, which are connected in packages to form a unit, wherein from meandering recesses and regional recesses of the middle plates together with the closed up to inlet and Ableitöffnungen outer plates cooling channels or - create spaces. On the other hand, there are also designs with two channels open on one side or having half shells (mostly of gray cast iron), which then form closed three-dimensional channels or spaces in the interior during assembly. In both variants, the suction lamellae and pressure lamellae are fastened separately via plug sockets or the like on the valve plate.
Abgesehen davon, dass die bekannten Ventilplatten damit aus relativ vielen Einzelteilen bestehen und in der Herstellung und Montage auch relativ kompliziert sind, haben sie auch den Nachteil, dass der zylinderseitig entstehende Schadraum, also das konstruktionsbedingt nicht weiter zu komprimierende Totvolumen, relativ groß ist, was den möglichen Liefergrad des Kompressors negativ beeinflusst. Apart from the fact that the known valve plates thus consist of relatively many items and in the manufacture and assembly are also relatively complicated, they also have the disadvantage that the cylinder-side resulting dead space, so the construction is not to be compressed dead volume, is relatively large, which negatively affects the possible delivery rate of the compressor.
Aufgabe der vorliegenden Erfindung ist es, eine Ventilplatte der genannten Art so auszubilden, dass die Herstellung und Montage vereinfacht wird und dass der konstruktionsbedingte zylinderseitige Schadraum möglichst klein bleibt. Object of the present invention is to provide a valve plate of the type mentioned in such a way that the production and assembly is simplified and that the design-related dead space cylinder remains as small as possible.
Diese Aufgabe wird gemäß der vorliegenden Erfindung dadurch gelöst, dass die Ventilplatte lediglich eine Halbschale mit zylinderseitig offenen Kühlkanälen aufweist, welche von einer zumindest entlang der Kühlkanäle abgedichteten Lamellenplatte überdeckt ist, die im Bereich der Saugöffnung(en) jeweils eine aus der Lamellenplatte herausgearbeitete, einseitig einstückig verbundene Sauglamelle aufweist. Damit kann eine auch bereits aus dem Stande der Technik bekannte (siehe beispielsweise DE 1 628 187 A1 oder EP 846 247 A1 ), die ge- samte Ventilplatte überdeckende und zusammen mit dieser zwischen Zylinder und Zylinderkopf eingespannte Lamellenplatte auch gleichzeitig zum zylinderseitigen Abschluss der in der Halbschale zylinderseitig offenen Kühlkanäle dienen, was durch den Wegfall der bisher bei den gekühlten Ventilplatten diese Kanäle bildenden bzw. abschließenden separaten zweiten Halbschale bzw. zylinderseitigen Abdeckplatte nicht nur Herstellung und Montage derartiger hohler Ventilplatten wesentlich vereinfacht, sondern darüber hinaus auch den zylinderseitigen Schadraum um bis zu 50 % (gegenüber bisherigen Ausführungen mit zwei Halbschalen) verringert. Auch wird die Abdichtung des Gesamtsystems einfacher, da eine Dichtebene entfällt. Zusätzlich vorteilhaft ist auch die damit einhergehende Gewichts- und Kostenersparnis. This object is achieved according to the present invention in that the valve plate has only a half-shell with cylinder-side open cooling channels, which of a At least along the cooling channels sealed lamella plate is covered, which in the region of the suction opening (s) in each case one out of the lamellae plate, one-sided integrally connected suction lamella has. Thus, a lamellar plate which covers the entire valve plate and is clamped together with it between the cylinder and the cylinder head and which is already known from the prior art (see, for example, DE 1 628 187 A1 or EP 846 247 A1), can also be used simultaneously with the cylinder-side closure in the Half shell serve on the cylinder side open cooling channels, which substantially eliminates the production and installation of such hollow valve plates by eliminating the previously formed in the cooled valve plates these channels or final separate second half-shell or cylinder-side cover plate, but also the cylinder-side dead space up to 50% (compared to previous versions with two half shells) reduced. Also, the sealing of the entire system is easier because a sealing level is eliminated. Additionally advantageous is the associated weight and cost savings.
In besonders bevorzugter weiterer Ausgestaltung der Erfindung ist die Lamellenplatte zumindest entlang der Kühlkanäle mit der Halbschale dauerhaft verbunden, vorzugsweise verschweißt oder verklebt, was eine Verbindung der Lamellenplatte mit der Halbschale bei gleichzeitiger Abdichtung lediglich der notwendigen Bereiche sicherstellt. Falls weitere in Lamellenplatte und/oder Halbschale vorgesehene Durchgangsöffnungen ebenfalls mit abzu- dichten sind, so kann dies sehr einfach durch Ausweitung der Verschweißung bzw. Verklebung auch auf diese Bereiche erfolgen. In a particularly preferred further embodiment of the invention, the lamella plate is permanently connected at least along the cooling channels with the half-shell, preferably welded or glued, which ensures a connection of the lamellar plate with the half shell while sealing only the necessary areas. If further passage openings provided in lamellar plate and / or half shell are also to be sealed off, this can also be done very simply by widening the welding or bonding to these areas as well.
Die Erfindung wird im Folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Fig. 1 zeigt dabei die perspektivische Ansicht einer erfindungsgemäß ausgebildeten Ventilplatte in Explosionsdarstellung von der Seite der Sauglamelle (also von der Zylinderseite aus), Fig. 2 die Ventilplatte nach Fig. 1 von der Druckventilseite in Explosionsdarstellung und Fig. 3 die Ventilplatte im zusammengebauten Zustand von der Seite der aufgeschweißten Lamellenplatte mit den Sauglamellen.  The invention will be explained in more detail below with reference to the embodiment shown in the drawing. Fig. 1 shows the perspective view of an inventively designed valve plate in an exploded view from the side of the suction plate (ie from the cylinder side), Fig. 2, the valve plate of Fig. 1 of the pressure valve side in exploded view and Fig. 3, the valve plate in the assembled state from the side of the welded lamella plate with the suction lamellae.
In allen Figuren ist lediglich die Ventilplatte 1 selbst dargestellt - der Zylinderblock eines der besseren Übersichtlichkeit weggelassenen Zweizylinder-Kolbenkompressors schließt in der Darstellung nach Fig. 2 unten an der Lamellenplatte 22 (zusammengebaut mit der Halbschale 3) an - oberhalb der Halbschale 3 (in der Darstellung nach Fig. 2) wäre der Zylinderkopf vorzustellen, der Saug- und Druckkanäle samt entsprechenden Anschlüssen, Kühlkanäle und dergleichen aufweist.  In all figures, only the valve plate 1 itself is shown - the cylinder block one of the better clarity omitted two-cylinder piston compressor closes in the illustration of FIG. 2 at the bottom of the lamella plate 22 (assembled with the half-shell 3) - above the half-shell 3 (in the Representation of FIG. 2), the cylinder head would be presented, the suction and pressure channels including the corresponding terminals, cooling channels and the like.
Die auf der Zylinderseite einseitig offene Kühlkanäle 4 aufweisende Halbschale 3 ist von der zumindest entlang der Kühlkanäle 4 abgedichteten Lamellenplatte 2 überdeckt, welche im Bereich der Saugöffnungen 5 jeweils eine aus der Lamellenplatte 2 herausgearbeitete, einseitig einstückig verbundene Sauglamelle 6 aufweist. Die Lamellenplatte 2 ist gemäß Fig. 3 hier nicht nur entlang der Kühlkanäle 4 mit der Halbschale 3 bleibend verbunden (beispielsweise durch die angedeutete Schweißraupe 7 oder eine entsprechende Verklebung), son- dern auch im Bereich um die Drucköffnungen 8, die gemäß Fig. 2 auf der Oberseite der Ventilplatte von separat befestigten Druckventilen 9 gesteuert werden. Davon abgesehen wäre aber natürlich auch eine separate Abdichtung dieser Drucköffnungen 8 möglich. The on the cylinder side unilaterally open cooling channels 4 having half-shell 3 is covered by the sealed at least along the cooling channels 4 fin plate 2, which in Section of the suction openings 5 each have a worked out of the slat plate 2, one-sided integrally connected suction plate 6 has. 3, not only along the cooling channels 4 with the half-shell 3 (for example, by the indicated bead 7 or a corresponding bond), but also in the area around the pressure openings 8, which according to FIG be controlled on the top of the valve plate by separately attached pressure valves 9. Apart from that, but of course, a separate sealing of these pressure openings 8 would be possible.
Die hohle Ventilplatte 1 ist auf diese Weise saugseitig aus lediglich zwei Teilen gebildet - der Halbschale 3 mit den an sich offenen Kühlkanälen 4 und der Lamellenplatte 2, die gleichzei- tig die Funktion der Sauglamelle und den Abschluss der Kühlkanäle 4 bereitstellt. Es gibt damit weniger Bauteile verbunden mit weniger Herstellungs- und Montageaufwand sowie weniger Gewicht und niedrigeren Kosten. Darüber hinaus ist auch unmittelbar einsichtig, dass der zylinderseitige Schadraum durch die dünne Lamellenplatte 2 gegenüber einer separaten Abdeckplatte bzw. zweiten zylinderseitigen Halbschale deutlich reduziert werden kann, was sich günstig auf den Liefergrad des Kompressors auswirkt.  The hollow valve plate 1 is formed in this way on the suction side from only two parts - the half-shell 3 with the per se open cooling channels 4 and the lamellar plate 2, which at the same time the function of the suction plate and the completion of the cooling channels 4 provides. There are thus fewer components associated with less manufacturing and assembly costs and less weight and lower costs. In addition, it is also immediately apparent that the cylinder-side dead space can be significantly reduced by the thin slat plate 2 with respect to a separate cover plate or second cylinder-side half-shell, which has a favorable effect on the degree of delivery of the compressor.
Nur der Vollständigkeit halber sind in Fig. 2 auch die Bohrungen 15 für die nicht weiter dargestellten Befestigungsschrauben des Zylinderkopfes, die sogenannte Regelbohrung 10 und Bohrungen 1 1 für Kühlwasserein- bzw. -auslass markiert. Mit 12 sind schließlich die Öffnungen in der Lamellenplatte 2 zum Durchgang der Befestigungsschrauben 13 für die Fixierung der Druckventile 9 am nicht dargestellten Zylinder bezeichnet und mit 14 die Durchgangsöffnungen zu den Drucköffnungen 8.  Only the sake of completeness are in Fig. 2, the holes 15 for the fastening screws of the cylinder head, not shown, the so-called control bore 10 and holes 1 1 marked for Kühlwasserein- or -auslass. With 12, finally, the openings in the lamella plate 2 for the passage of the fastening screws 13 for fixing the pressure valves 9 on the cylinder, not shown, and 14 designates the passage openings to the pressure openings. 8
