Abstract

The pressure pipe (3) is clamped between an injector element and a connector. The pipe has a groove (7) around the end facing the connector (4). The connector has apertures (8a,b), which are located in the groove when installed. A U-shaped spring bracket (6) is pushed over apertures and groove, so that an axial positive connection is formed, and pressure pipe and connector can be turned against each other.

Description

Die Erfindung bezieht sich auf eine Vorrichtung gemaß dem Gattungsbegriff des Patentanspruches 1.The invention relates to a device according to the preamble of the claim 1.

Bei Einspritzeinrichtungen, bei denen ein Einspritzelement in Verlängerung der Zylinderachse angeordnet ist und die Einspritzleitung seitlich an den Zylinderkopf herangeführt wird ist der Zylinderkopf mit einer Bohrung versehen, durch welche ein Druckrohr geführt wird, um die Einspritzleitung über ein Anschlußstück mit dem Einspritzelement in Form einer Einspritzdüse oder eines Injektors bei Common Rail zu verbinden. Bei einer Einspritzeinrichtung dieser Art hat es sich gezeigt, daß bei einer Demontage große Schwierigkeiten bei der Herausnahme des Druckrohres auftreten.For injection devices in which an injection element extends the cylinder axis is arranged and the injection line leads laterally to the cylinder head the cylinder head is provided with a hole through which a pressure pipe is guided to the injection line via a connector with the injection element in the form of an injection nozzle or an injector for common rail. With an injection device of this type, it has been shown that during disassembly great difficulty in removing the pressure pipe.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur leichten Demontage des Druckrohres zu entwickeln.The invention is therefore based on the object of a device for easy disassembly to develop the pressure pipe.

Gelöst wird diese Aufgabe zum einen durch die kennzeichnenden Merkmale des Patentanspruches 1.This problem is solved on the one hand by the characterizing features of the patent claim 1.

Durch die formschlüssige Verbindung die der Federbügel zwischen dem Anschlußstück und dem Druckrohr herstellt kann das Druckrohr ohne weiteres aus der Bohrung im Zylinderkopf herausgezogen werden. Der Federbügel behindert dabei nicht die beim Herausschrauben notwendige Drehung des Anschlußstückes. Due to the positive connection of the spring clip between the connector and the pressure pipe manufactures the pressure pipe easily from the bore be pulled out in the cylinder head. The spring clip does not hinder the necessary rotation of the connector when unscrewing.

Die gleiche Aufgabe kann zum anderen durch die kennzeichnenden Merkmale des Patentanspruches 2 gelöst werden.The same task can be achieved by the characterizing features of the claim 2 can be solved.

Der Spannstift verbindet ebenfalls das Druckrohr und das Anschlußstück formschlüssig, so daß das Druckrohr bei Demontage leicht aus der Bohrung im Zylinderkopf herausgezogen werden kann, ohne daß dabei die Drehbewegung des Anschlußstückes behindert wird.The dowel pin also connects the pressure pipe and the connector with a positive fit, so that the pressure pipe is easily pulled out of the hole in the cylinder head when dismantling can be without hindering the rotational movement of the connector becomes.

Fig. 1 zeigt im Schnitt einen Zylinderkopf 1 mit einer Einspritzeinrichtung die im wesentlichen aus einem Einspritzelement 2, einem Druckrohr 3 und einem Anschlußelement 4 zum Anschluß einer Einspritzleitung gebildet wird. Das Druckrohr 3 durchdringt den Zylinderkopf 1 in einer Bohrung 5. Zur Abdichtung ist das Druckrohr an beiden Enden mit balligen Dichtflächen versehen und wird zwischen Anschlußstück 4 und dem Einspritzelement 2 eingespannt. Es hat sich nun bei Einspritzeinrichtungen dieser Art gezeigt, daß sich das Druckrohr 3 bei Demontage nur schwer aus der Bohrung 5 herausziehen läßt. Dieses Problem wird erfindungsgemäß zum einen dadurch gelöst, daß man einen Federbügel 6 vorsieht, welcher das Druckrohr 3 und das Anschlußstück 4 derart formschlüssig verbindet, daß man das Druckrohr 3 über das Anschlußstück 4 herausziehen kann. Zu diesem Zweck ist das Druckrohr 3 an dem, dem Anschlußstück 4 zugewandten Ende mit einer umlaufenden Nut 7 versehen, in welche der Federbügel 6 eingreift. Zur Verbindung von Federbügel 6 und Anschlußstück 4 weist dieses seitliche Ausnehmungen 8a, 8b auf (siehe auch Fig. 2). Der Federbügel 6 ist also in diesen Ausnehmungen 8a, 8b so gehalten, daß er sich nicht axial verschieben kann.Fig. 1 shows in section a cylinder head 1 with an injection device which essentially consisting of an injection element 2, a pressure pipe 3 and a connecting element 4 is formed for connecting an injection line. The pressure pipe 3 penetrates the cylinder head 1 in a bore 5. The pressure pipe is on for sealing both ends with spherical sealing surfaces and is between connector 4 and the injection element 2 clamped. It has now become injectors this type shown that the pressure pipe 3 is difficult to remove from the bore 5 can be pulled out. According to the invention, this problem is, firstly, thereby solved that one provides a spring clip 6, which the pressure pipe 3 and the connector 4 such a positive connection that the pressure pipe 3 via the connector 4 can pull out. For this purpose, the pressure pipe 3 on the Connector 4 facing end with a circumferential groove 7, in which the spring clip 6 engages. For connecting spring clip 6 and connector 4 this has lateral recesses 8a, 8b (see also FIG. 2). The spring clip 6 is thus held in these recesses 8a, 8b so that it does not move axially can.

Bei der Demontage wird zunächst das Anschlußstück 4 aus dem Zylinderkopf 1 herausgeschraubt, wobei sich der Federbügel 6 mitdreht. In der Nut 7 kann sich der Federbügel 6 gegenüber dem Druckrohr 3 ebenfalls drehen, ist jedoch in axialer Richtung geführt und nimmt folglich beim Herausschrauben des Anschlußstückes 4 das Druckrohr 3 mit.When dismantling, the connector 4 is first unscrewed from the cylinder head 1, the spring clip 6 rotates with it. The spring clip can be in the groove 7 6 also turn relative to the pressure pipe 3, but is in the axial direction performed and consequently takes the pressure tube when unscrewing the connector 4 3 with.

Einen Schnitt II-II zeigt Fig. 2. Der Federbügel 6 steckt in der Nut 7 des Druckrohres 3 und wird in dieser Nut axial geführt. Die axiale Führung des Federbügels 6 im Anschlußstück 4 wird durch die Ausnehmungen 8a und 8b bewerkstelligt.A section II-II is shown in FIG. 2. The spring clip 6 is in the groove 7 of the pressure pipe 3 and is guided axially in this groove. The axial guidance of the spring clip 6 in the connector 4 is brought about by the recesses 8a and 8b.

Eine weitere Ausführungsform zur Demontage des Druckrohres 3 ist in Fig. 3 dargestellt. Das Druckrohr 3 weist wieder eine umlaufende Nut 7 auf. An Stelle des Federbügels ist hier mindestens ein Spannstift 9a vorgesehen, welcher das Anschlußstück 4 in einer Bohrung durchdringt. Beim Herausschrauben des Anschlußstückes 4 zieht der Spannstift 9a über die Nut 7 das Druckrohr 3 aus der Bohrung 5 im Zylinderkopf 1. Neben dem Spannstift 9a kann noch ein zweiter Spannstift 9b vorgesehen werden.A further embodiment for dismantling the pressure pipe 3 is shown in FIG. 3. The pressure pipe 3 again has a circumferential groove 7. Instead of the spring clip at least one dowel pin 9a is provided here, which connects the connecting piece 4 penetrates in a hole. When unscrewing the connector 4, the Dowel pin 9a via the groove 7, the pressure pipe 3 out of the bore 5 in the cylinder head 1. In addition to the roll pin 9a, a second roll pin 9b can also be provided.

Fig. 4 zeigt einen Schnitt IV-IV in der Ebene der Nut 7. Die Spannstifte 9a, 9b durchdringen das Anschlußstück 4 und sind axial in der umlaufenden Nut 7 des Druckrohres 3 geführt.Fig. 4 shows a section IV-IV in the plane of the groove 7. The dowel pins 9a, 9b penetrate the connector 4 and are axially in the circumferential groove 7 of the pressure pipe 3 led.
