Definitions
- the invention relates to a hollow valve plate for liquid-cooled multi-valve valves of a reciprocating compressor.
- 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.
- 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. 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.
- the entire valve plate overlapping and clamped together with this between the cylinder and cylinder head lamellae also serve the cylinder side completion of the half-shell cylinder side open cooling channels, which by eliminating the previously formed in the cooled valve plates these channels or final separate second half shell or cylinder-side cover plate not only makes production and installation of such hollow valve plates much easier, but also reduces the cylinder-side dead space by up to 50% (compared to previous versions with two half-shells). Also, the sealing of the entire system is easier because a sealing level is eliminated. Additionally advantageous is the associated weight and cost savings.
- 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.
- Fig. 1 shows the perspective view of an inventively designed valve plate in exploded view from the side of the suction plate (ie from the cylinder side), Fig. 2 the valve plate after Fig. 1 from the pressure valve side in exploded view and Fig. 3 the valve plate in the assembled state from the side of the welded plate slats with the Sauglamellen.
- valve plate 1 itself is shown - the cylinder block of a better clarity omitted two-cylinder piston compressor concludes in the presentation Fig. 2 at the bottom of the lamella plate 22 (assembled with the half-shell 3) on - above the half-shell 3 (in the illustration Fig. 2 ), the cylinder head would have to be presented, the suction and pressure channels including corresponding ports, cooling channels and the like.
- 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.
- the slat plate 2 is according to Fig. 3 not only along the cooling channels 4 with the half-shell 3 permanently connected (for example, by the indicated weld bead 7 or a corresponding bond), but also in the area around the pressure openings 8, according to Fig. 2 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.
- the hollow valve plate 1 is formed in this way on the suction side of only two parts - the half-shell 3 with the per se open cooling channels 4 and the plate plate 2, which simultaneously provides the function of the suction plate and the completion of the cooling channels 4.
- 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.

Description
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 (siehe beispielsweise
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.
Eine von solchen Ausführungen ist z.B. aus dem Dokument
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. 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
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 abzudichten 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.
Die Erfindung wird im Folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.
In allen Figuren ist lediglich die Ventilplatte 1 selbst dargestellt - der Zylinderblock eines der besseren Übersichtlichkeit weggelassenen Zweizylinder-Kolbenkompressors schließt in der Darstellung nach
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
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 gleichzeitig 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
