Abstract
Description
Die Erfindung betrifft eine gattungsgemäße Hubkolben-Brennkraft maschine sogenannte Kurbelschleifenmaschinen, wie sie beispiels weise die DE-OS 35 00 644, F01B 23/08, beschreibt, zeichnen sich dadurch aus, daß die starr, d. h. nicht schwenkbar, mit einem Hubkolben der Maschine verbundene Kolbenstange eine Kurbelschleife trägt, die einen Gleitstein an einem Kurbelzapfen der zugehörigen Kurbelwelle quer zur Richtung der Kolbenbewegung verschiebbar auf nimmt.The invention relates to a generic reciprocating piston internal combustion engine machine so-called crank grinding machines, such as those as described in DE-OS 35 00 644, F01B 23/08, stand out in that the rigid, d. H. not swiveling, with one Reciprocating piston of the machine connected piston rod to a crank loop who carries a sliding block on a crank pin of the associated Crankshaft slidable transversely to the direction of piston movement takes.
Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln die Tatsache der durch die Bewegungen des Hubkolbens erfolgenden peri odischen Größenänderung des abgedichteten Raums auf der Kolbenrück seite nutzbar zu machen.The invention is based, with simple means the Fact of the peri resulting from the movements of the reciprocating piston Odical resizing of the sealed space on the piston rear make the site usable.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kenn zeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the drawing features of the main claim, advantageous training the invention describe the subclaims.
Die Erfindung sieht also in vorteilhafter Weise in einem ohnehin erforderlichen Bauteil der Maschine, nämlich der Platte zum dichten Durchführen der Kolbenstange, Zu- und Abfuhrkanäle und im Zuge der selben Zu- und Abfuhrventile vor, so daß der betrachtete auf der Kolbenrückseite liegende Raum als Verdichterraum beispielsweise zur Lieferung hochgespannter Ladeluft für die Brennkraftmaschine selbst herangezogen werden kann. The invention therefore advantageously sees in any case required part of the machine, namely the plate for sealing Carrying out the piston rod, supply and discharge channels and in the course of same supply and discharge valves before, so that the considered on the Piston back space as a compressor space for example Delivery of high-tension charge air for the internal combustion engine itself can be used.
Zwei Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnung erläutert, deren Figuren Längsschnitte durch die ge samte Maschine bzw. durch den Bereich der mit den Zu- und Abfuhr kanälen versehenen Platte wiedergeben.Two embodiments of the invention are described below of the drawing, the figures of which are longitudinal sections through the ge entire machine or through the area with the supply and discharge play backed disc.
Betrachtet man zunächst Fig. 1, so erkennt man bei 1 den in einem hier wassergekühlten Zylinder 2 laufenden Hubkolben. Oberhalb des selben befindet sich der Arbeits- oder Verbrennungsraum 3 der Ma schine, der über die mit nockenbestückten Hubventilen 4 und 5 ver sehenen Ladungswechselleitungen 6 und 7 mit Ladeluft bzw. Frischgas beliefert und von verbrannten Abgasen befreit wird. Dieser Ladungs wechsel ist absolut üblich und braucht im Einzelnen nicht erläutert zu werden.Looking first at FIG. 1, one can see at 1 the reciprocating piston running in a water-cooled cylinder 2 here. Above the same is the working or combustion chamber 3 of the machine, which is supplied with charge air or fresh gas and freed of burnt exhaust gases via the charge exchange lines 6 and 7 provided with cam valves 4 and 5 . This charge change is absolutely common and does not need to be explained in detail.
Starr mit dem Kolben 1 verbunden ist die Kolbenstange 8, da sie nur Längsbewegungen in Richtung der Bewegungen des Kolbens 1, nicht aber wie bei üblichen Hubkolbenmaschinen auch Schwenkbewegungen um einen Kolbenzapfen ausführt. Sie durchsetzt dicht die allgemein mit 9 bezeichnete Platte, die einen infolge der Bewegung des Kolbens 1 periodisch größenveränderbaren Raum 10 begrenzt und diesen vom Kur belraum 11 trennt. Innerhalb desselben ist starr mit der Kolben stange 8 die Kurbelschleife 12 verbunden, die den Gleitstein 13 auf der Kurbelwange 14 einer im übrigen nicht dargestellten, da üb lichen Kurbelwelle der Maschine querverschiebbar führt. Durch diese Anordnung werden also Längsbewegungen der Kolbenstange 8 in Rotationsbewegungen der Kurbelwelle umgesetzt.The piston rod 8 is rigidly connected to the piston 1 , since it only executes longitudinal movements in the direction of the movements of the piston 1 , but not, as in conventional reciprocating piston machines, also swiveling movements around a piston pin. It penetrates tightly the plate generally designated 9 , which limits a space 10 which can be changed in size periodically as a result of the movement of the piston 1 and separates it from the cure belraum 11 . Within the same is rigidly connected to the piston rod 8, the crank loop 12 , the sliding block 13 on the crank arm 14 of an otherwise not shown, since ü union crankshaft of the machine leads transversely. With this arrangement, longitudinal movements of the piston rod 8 are converted into rotational movements of the crankshaft.
Die Kurbelschlaufe 12 befindet sich innerhalb des Kurbelgehäuses 14, das auch eine weitere Führung 15 für das untere Ende der Kurbelstange 8 enthält. Unterhalb der beschriebenen Gesamtanordnung erkennt man die Ölwanne 16.The crank loop 12 is located within the crankcase 14 , which also contains a further guide 15 for the lower end of the crank rod 8 . The oil pan 16 can be seen below the overall arrangement described.
Wie bereits angegeben, ändert sich die Größe des Raums 10 in Ab hängigkeit von der Bewegung des Kolbens 1 periodisch. Diese Tat sache wird bei der Erfindung dadurch ausgenutzt, daß der Raum 10 als Verdichterraum mit in diesem Ausführungsbeispiel einem Zufuhr kanal 17 und einem Abfuhrkanal 18 für ein zu verdichtendes Medium, hier Ladeluft für die Maschine, versehen ist. Diese Kanäle 17 und 18 sind in die allgemein mit 9 bezeichnete Führungsplatte einge arbeitet, und zwar genauer gesagt in den rahmenähnlichen äußeren Bereich 19 derselben, der sich in Fig. 1 in Richtung nach unten in dem Kurbelgehäuse 14 fortsetzt und von dem flacheren inneren Be reich 20, der zur dichten Durchführung der Kolbenstange 8 ausge bildet ist, ergänzt wird. Beide Kanäle 17 und 18 sind mit hier als Zungenventilen ausgebildeten Rückschlagventilen 21 und 22 als Zu- bzw. Abfuhrventil versehen, von denen das Ventil 21 eingangsseitig mit der Lufteinlaßleitung 23 in Verbindung steht, während das andere Ventil 22 in die Ladeluftleitung 6 mündet, in deren Verlauf der Ladeluftkühler 24 und die als Leistungsstellglied der Maschine dienende Drosselklappe 25 vorgesehen sind. Das bedeutet, daß bei Aufwärtsbewegung des Kolbens 1 infolge der sich einstellenden Druckverhältnisse nur das Zufuhrventil 21, nicht aber das Abfuhr ventil 22 sich öffnet; bei Abwärtsbewegung des Kolbens 1 kehren sich die Verhältnisse um.As already stated, the size of the space 10 changes periodically depending on the movement of the piston 1 . This fact is exploited in the invention in that the space 10 as a compressor space with a feed channel 17 and a discharge channel 18 for a medium to be compressed, here charge air for the machine, is provided in this embodiment. These channels 17 and 18 are in the generally designated 9 guide plate works, more specifically in the frame-like outer portion 19 of the same, which continues in Fig. 1 in the downward direction in the crankcase 14 and rich from the flatter inner loading 20 , which is formed for the tight implementation of the piston rod 8 , is added. Both channels 17 and 18 are provided with check valves 21 and 22 designed as tongue valves as supply and discharge valves, of which the valve 21 is connected on the inlet side to the air inlet line 23 , while the other valve 22 opens into the charge air line 6 , in the latter Course of the charge air cooler 24 and the throttle valve 25 serving as the power actuator of the machine are provided. This means that when the piston 1 moves upward, only the supply valve 21 , but not the discharge valve 22 , opens as a result of the pressure conditions which arise; when piston 1 moves down, the situation is reversed.
Während in der Ausführungsform nach Fig. 1 Zungenventile 21 und 22 Einsatz finden, zeigt Fig. 2 ein Beispiel mit einer einteiligen Führungsplatte 30; die von der Kolbenstange durchsetzte Öffnung 31 ist mit einer Dichtung 32 versehen. Der dem Teil 2 in Fig. 1 ent sprechende Zylinder trägt das Bezugszeichen 33. In diesem Ausfüh rungsbeispiel sind die dem Zu- und Abfuhrkanal 34 bzw. 35 zugeord neten Ventile 36 und 37 als Hubventile ausgebildet; sie stellen je doch wiederum druckabhängig betätigte Rückschlagventile dar.While tongue valves 21 and 22 are used in the embodiment according to FIG. 1, FIG. 2 shows an example with a one-piece guide plate 30 ; the opening 31 penetrated by the piston rod is provided with a seal 32 . The part 2 in FIG. 1 speaking cylinder has the reference numeral 33 . In this exemplary embodiment, the supply and discharge channels 34 and 35 assigned valves 36 and 37 are designed as lift valves; however, they in turn represent pressure-operated check valves.
Mit der Erfindung ist demgemäß eine gattungsgemäße Maschine ge schaffen, die mit einfachen Mitteln zu einem Verdichter ergänzt ist.With the invention is accordingly a generic machine ge create that complements to a compressor with simple means is.
