Die Erfindung betrifft die Ausbildung des Zylinderkopfes und des im Zylinderkopf angeordneten, kombinierten Druck- und Saugventils mit konzentrischer Anordnung der Saug- und Druckventile bei schneilauf enden Kolbenluftkompressoren, bei denen das Saugventil in der Verlängerung des aus dem Zylinderkopf zentral nach dem Ventil hin austretenden Luftansaugkanals angeordnet ist und bei dem der Ventilkörper durch Preßsitz in einer Ausdrehung des Zylinderkopfes gehalten ist und der Außendurohmesser des Ventilkörpers größer ist als der Innendurchmesser des Zylinders, insbesondere für Kleinkolbenkompressoren für die Beschaffung von Bremsluft bei Kraftfahrzeugen. The invention relates to the design of the cylinder head and the combined pressure and suction valve arranged in the cylinder head concentric arrangement of the suction and pressure valves in the case of high-speed piston air compressors, in which the suction valve is in the extension of the cylinder head centrally after the valve is arranged towards exiting air intake duct and in which the valve body by a press fit in a recess in the cylinder head is held and the outer diameter of the valve body is larger than the inner diameter of the cylinder, especially for small piston compressors for the procurement of brake air for motor vehicles.
Bei Kolbenverdichtern ist es bekannt, einen zweistückigen Ventilkörper für Ansaugventile oder Druckventile, dessen Außendürchmesser größer ist als der Innendurchmesser des Zylinders, zwisehen Zylinderkopf und Zylindermantel in einer Ausdrehung des Zylinderkopfes durch Preßsitz zu halten.In the case of reciprocating compressors, it is known to use a two-piece valve body for suction valves or pressure valves, the outer diameter of which is greater than the inner diameter of the cylinder, between Cylinder head and cylinder jacket in a recess of the cylinder head by a press fit to keep.
Weiterhin ist es bekannt, die Saugventile in der Verlängerung des zentralen Luftansaugkanals an dem Zylinderkopf, konzentrisch umgeben von den Durchtrittsschlitzen für die Druckventile, anzubringen, in dem eine entsprechend geformte, federnde Platte membranartige Abschlußteile für die verschiedenen öffnungen bildet.It is also known to connect the suction valves in the extension of the central air intake duct to be attached to the cylinder head, concentrically surrounded by the passage slots for the pressure valves, in which a correspondingly shaped, resilient plate membrane-like end parts for which forms different openings.
Es ist ferner bekannt, einen zweistückigen Ventilkörper von größerem Durchmesser als der Innendurchmesser des Zylinders zwischen Zylinderkopf und Zylinder durch Preßsitz zu halten, wobei in dem aus zwei verschraubten Platten gebildeten Körper konzentrische Durchtrittsschlitze sowohl für das Ansaug- als auoh das Druckventil angeordnet und diese Ventile zwischen den Platten geführt sind.It is also known to have a two-piece valve body of larger diameter than that To hold the inner diameter of the cylinder between the cylinder head and cylinder by press fit, with both concentric passage slots in the body formed from two screwed plates arranged for the suction as auoh the pressure valve and these valves between the plates are led.

Ventilanordnungen dieser Art haben verschiedene Nachteile, da sie einmal durch ihren Aufbau
mehr oder weniger verwickelt sind und weiterhin auch die auftretenden Wärmestauungen nicht ausreichend,
abführen können. Membranventile sind bei schnellaufenden Kompressoren insbesondere
deshalb weniger geeignet, da sie leicht zum Flattern neigen. Sie unterliegen in besonderem Maße Beeinträchtigungen
durch Wärmestauungen.
ίο Die vorliegende Erfindung bezweckt die Vermeidung dieser Nachteile und betrifft insbesondere
auch einen einfachen Aufbau eines solchen Ventils, wobei eine Erleichterung der Montage und der
Auswechselung erzielt wird. Zu diesem Zweck werden derartige Ventile in der Weise ausgebildet,
daß der Sitz des als federbelastetes Scheibenventil ausgebildeten Saugventils durch den aus dem
Zylinderkopf herausgearbeiteten Stirnrand des Luftzuführungskanals gebildet ist sowie daß der
die Durchtrittsstihlitze für das Ansaugventil aufweisende
einstückige, plattenförmige halternde Ventilkörper zugleich konzentrisch an das Ansaugventil
angeordnete Durchtrittsschlitze für das Druckventil aufweist, deren Ränder den Sitz für
das Druckventil bilden.Valve arrangements of this type have various disadvantages, since they are more or less entangled due to their structure and still cannot adequately dissipate the heat build-up that occurs. Diaphragm valves are particularly less suitable for high-speed compressors because they tend to flutter easily. They are particularly subject to impairments from heat build-up.
The present invention aims to avoid these disadvantages and in particular also relates to a simple structure of such a valve, making assembly and replacement easier. For this purpose, such valves are designed in such a way that the seat of the suction valve, which is designed as a spring-loaded disc valve, is formed by the end edge of the air supply duct carved out of the cylinder head and that the one-piece, plate-shaped retaining valve body, which has the passage stiffener for the suction valve, is concentric with the suction valve arranged through slots for the pressure valve, the edges of which form the seat for the pressure valve.
Der einstückige Ventilkörper unter Verwendung eines zentralen federbelasteten Scheibenventils ergibt einen einfachen Aufbau, so daß die Montage, Auswechslung oder Reparatur wesentlich erleichtert ist. Weiterhin bedingt der einstückige Ventilkörper eine gute Wärmeableitung, so daß Wärmestauungen an den gefährdeten Stellen herabgesetzt oder vermieden werden.The one-piece valve body using a central spring-loaded disc valve results in a simple structure, so that the assembly, Replacement or repair is much easier. Furthermore, the one-piece valve body requires good heat dissipation, so that heat build-up at the endangered areas or reduced be avoided.
Das einstückige Scheibenventil für das Ansaugen in dem zentralen Ansaugkanal ergibt gegenüber einer Reihe von Einzelventilen eine günstigere Wirkung, da ein größerer Querschnitt beaufschlagt wird und demzufolge eine schlagartige öffnung der Durchtrittsschlitze eintritt, wobei weiterhin die große Fläche des Scheibenventils durch die angesaugte Luft in besonderem Maße die Kühlwirkung vergrößert.The one-piece disc valve for suction in the central suction channel results in opposite a series of individual valves has a more favorable effect, since a larger cross-section is applied and consequently a sudden opening of the passage slots occurs, and continues the large area of the butterfly valve due to the air sucked in, particularly the cooling effect enlarged.
Die Erfindung ist in der Zeichnung im Schnitt dargestellt.The invention is shown in section in the drawing.
Auf dem Zylinder 1 ist der Zylinderkopf 2 in der üblichen Weise befestigt. 3 ist der Ventilkörper, der in einer entsprechenden Ausdrehung des Zylinderkopfes eingesetzt ist. Der Ventilkörper ist einstückig. Sein Außendurchmesser ist um ein geringes Maß größer als die Zylinderbohrung. Er wird in dem Zylinderkopf mit Preßsitz gehalten. Das Ansaugventil ist das innenliegende Ventil mit den im Ventilkörper 3 angeordneten Durchtrittssdhlitzen 4, die im Bereich des zentral nach dem Ventil hin auslaufenden Luftkanals 5 vorgesehen sind, so daß ein möglichst geradliniger Luftdurchfluß vorhanden ist, der noch dadurch begünstigt wird, daß der Luftansaugkanal auch nach außen hin zum Einlaßstutzen zentral weiterläuft. The cylinder head 2 is attached to the cylinder 1 in the usual manner. 3 is the valve body, which is inserted in a corresponding recess in the cylinder head. The valve body is in one piece. Its outside diameter is slightly larger than the cylinder bore. He is held in the cylinder head with an interference fit. The suction valve is the internal valve with the arranged in the valve body 3 Durchtrittssdhlitzen 4, which in the area of the centrally after the valve tapering air duct 5 are provided, so that a straight as possible Air flow is present, which is further promoted by the fact that the air intake duct also continues to run centrally to the outside towards the inlet port.
Für bereits vorhandene Anlagen wird zweckmäßig ein seitlicher Eintritts stutzen 6 in den zentralen Teil des Luftansaugkanals geführt. Der Sitz der Ventilplatte 7 des Ansaugventils wird durch den entsprechend herausgearbeiteten Rand der Austrittsöffnung des Ansaugkanals S gebildet; er liegt also im Zylinderkopf. 8 ist die Ventilfeder für das Ansaugventil, die sich gegen eine entsprechende Eindrehung des Ventilkörpers abstützt.For existing systems, a side inlet connector 6 is useful in the central Part of the air intake duct out. The seat of the valve plate 7 of the suction valve is through the correspondingly worked out edge of the outlet opening of the intake channel S is formed; he so lies in the cylinder head. 8 is the valve spring for the suction valve, which is opposed to a corresponding one Rotation of the valve body is supported.
In dem Ventilkörper 3 sind, konzentrisch das Ansaugventil umschließend, dieDurchtrittsschlitzeo, für das Druckventil angeordnet, dessen Sitz aus dem Ventilkörper selbst herausgearbeitet ist. sind die Ventilfedern des Druckventils, die die Ventilplatte 11 beeinflussen und in Bohrungen des Zylinderkopfes eingelagert und abgestützt sind,In the valve body 3, concentrically surrounding the suction valve, the passage slots o, arranged for the pressure valve, the seat of which is carved out of the valve body itself. are the valve springs of the pressure valve, which influence the valve plate 11 and are located in the bores of the Cylinder head are stored and supported,
