Each spray nozzle is connected to a cylinder crankcase and to hers provide the free end with a bend directed towards the chain.
Es ist Aufgabe der Erfindung die Spritzdüsenvorrichtung für einen Kettentrieb einer Brennkraftmaschine so auszubilden, dass sie bei einfacher Bauweise die Schmierfunktion verbessert.It is an object of the invention the spray nozzle device for a chain drive Train the internal combustion engine so that it has the lubrication function with a simple construction improved.
Erfindungsgemäss wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalte.According to the invention, this object is achieved by the features of patent claim 1. Further features embodying the invention are contained in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die Spritzdüsenvorrichtung für eine bspw. zwei Zylinderreihen aufweisende Brennkraftmaschine mit einer einzigen Spritzdüse für den Kettentrieb auskommt, die, weil benachbart der Kette des Kettentriebs und einem Gleitbelag der Spannvorrichtung angeordnet, eine vortreffliche Schmierung des Kettentriebs gewährleistet. Die Spritzdüse selbst ist ein leicht herstellbares und montierbares Bauteil, das sich auf einfache Weise in vorgegebene Raumverhältnisse an einer Stirnseite der Brennkraftmaschine integrieren lässt.The main advantages achieved with the invention are that the Spray nozzle device for an internal combustion engine having, for example, two rows of cylinders with a single spray nozzle for the chain drive, which is because adjacent to the chain of the chain drive and a sliding lining of the tensioning device, an excellent Lubrication of the chain drive guaranteed. The spray nozzle itself is a lightweight producible and assemble component that can easily be given in predetermined Space can be integrated on one end of the internal combustion engine.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehen näher beschrieben wird.In the drawing, an embodiment of the invention is shown, which are below is described.

Eine nicht näher gezeigte Brennkraftmaschine 1 umfasst in V-Form angeordnete Zylinderreihen 2, 3 und an einer Stirnseite 4 einen Kettentrieb 5. Der Kettentrieb 5 treibt mittels einer Kette 6 von einer Kurbelwelle 7 aus, gelagert in einem Kurbelgehäuse 8, oberhalb von Zylinderköpfen vorgesehene Nockenwellen 9, 10 und 11, 12 an. Die Kette 6 umschlingt oberhalb der Kurbelwelle 7 ein Umlenkrad 13, wodurch sich benachbarte Kettenstränge 14 und 15 des Kette 6 ergeben. An diesen Kettensträngen 14 und 15 liegen Spannvorrichtungen 16 und 17, die durch Träger 18 und Gleitbeläge 19 gebildet werden; die Gleitbeläge 19 arbeiten mit den Kettensträngen 14 und 15 zusammen.An internal combustion engine 1 ( not shown in detail ) comprises rows of cylinders 2 , 3 arranged in a V-shape and a chain drive 5 on an end face 4 . The chain drive 5 drives by means of a chain 6 from a crankshaft 7 , mounted in a crankcase 8 , camshafts 9 , 10 and 11 , 12 provided above the cylinder heads. The chain 6 wraps around a deflection wheel 13 above the crankshaft 7 , which results in adjacent chain strands 14 and 15 of the chain 6 . On these chain strands 14 and 15 there are tensioning devices 16 and 17 which are formed by carriers 18 and sliding linings 19 ; the sliding pads 19 work together with the chain strands 14 and 15 .
Zur Versorgung der des Kettentriebs 5 mit Schmieröl ist an der Stirnseite 4 des Kurbelgehäuses 8 eine Spritzdüsenvorrichtung 20 angeordnet, die zumindest für eine Zylinderreihe z. B. 2 nur eine einzige Spritzdüse 21 aufweist. Die eine zylinderische Form aufweisende Spritzdüse 21, die in eine mit einem nicht näher gezeigten Schmierölkreislauf der Brennkraftmaschine 1 verbundene Aufnahmeöffnung 22 des Kurbelgehäuses 8 eingesetzt ist, ist benachbart der Gleitbeläge 19 und der Kette 6 angeordnet, dergestalt, dass eine freie Seite 23 der Spritzdüse 21 die Kette 6 und auch die Gleitbeläge 19 - in Querrichtung - gesehen überragt. Dabei ist die Spritzdüse 21 an der freien Seite 23 mit radialen Düsenöffnungen 24 und 25 versehen, die auf die Kette 6 und auf die Gleitbeläge 19 gerichtet sind. To supply the chain drive 5 with lubricating oil, a spray nozzle device 20 is arranged on the end face 4 of the crankcase 8 , which at least for one row of cylinders z. B. 2 has only a single spray nozzle 21 . The spray nozzle 21 , which has a cylindrical shape and is inserted into a receiving opening 22 of the crankcase 8 which is connected to a lubricating oil circuit of the internal combustion engine 1 , is arranged adjacent to the sliding linings 19 and the chain 6 , such that a free side 23 of the spray nozzle 21 the chain 6 and also the sliding pads 19 - seen in the transverse direction - towering over. The spray nozzle 21 is provided on the free side 23 with radial nozzle openings 24 and 25 which are directed onto the chain 6 and the sliding linings 19 .
Im Ausführungsbeispiel ist die Spritzdüse 21 zwischen den benachbarten Kettensträngen 14 und 15 angeordnet, und sie ragt in eine Ausnehmung 26 einer zwischen besagten Kettensträngen verlaufenden Verstärkungsrippe 27 eines Steuertriebdeckels 28 hinein, welche Verstärkungsrippe 27 an einer Innenseite 29 des Steuertriebdeckels 28 angebracht ist. Der Steuertriebdeckel 28 umhüllt den Kettentrieb 5 vollständig an der Stirnseite 4 des Kurbelgehäuses 8 und ist unter Vermittlung von Schrauben mit besagtem Kurbelgehäuse verbunden.In the exemplary embodiment, the spray nozzle 21 is arranged between the adjacent chain strands 14 and 15 , and it projects into a recess 26 of a reinforcing rib 27 of a timing gear cover 28 running between said chain strands, which reinforcing rib 27 is attached to an inside 29 of the timing gear cover 28 . The timing gear cover 28 completely surrounds the chain drive 5 on the end face 4 of the crankcase 8 and is connected to said crankcase by means of screws.
Schliesslich ist die Spritzdüse 21 in ein Gewinde 30 des Kurbelgehäuses 8 eingedreht und zur Montagevereinfachung mit einem Schraubenmutterabschnitt 31 und einem an besagtem Kurbelgehäuse sich abstützende Anschlag 32 versehen.Finally, the spray nozzle 21 is screwed into a thread 30 of the crankcase 8 and is provided with a screw nut section 31 and a stop 32 supported on said crankcase in order to simplify assembly.
