Definitions
- the invention relates to a device according to the preamble of the claim 1, respectively. of claim 2.
- a device is for example known from the publication WO 97 02426 A.
- the invention is therefore based on the object of a device for easy disassembly to develop the pressure pipe.
- 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 rotation of the connector becomes.
- 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 lets pull this problem out according to the invention on the one hand solved that one provides a spring clip 6, which the pressure pipe 3 and the connector 4 connects in such a positive manner that the pressure pipe 3 is connected via the connector 4 can pull out.
- the pressure pipe 3 on the Connector 4 facing end with a circumferential groove 7, in which the spring clip 6 engages.
- 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.
- the connector 4 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 pipe when unscrewing the connector 4 3 with.
- 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 accomplished by the recesses 8a and 8b.
- FIG. 3 A further embodiment for dismantling the pressure pipe 3 is shown in FIG. 3.
- the pressure pipe 3 again has a circumferential groove 7.
- at least one dowel pin 9a is provided here, which connects the connecting piece 4 penetrates in a hole.
- the Dowel pin 9a via the groove 7, the pressure pipe 3 from the bore 5 in the cylinder head 1.
- a second roll pin 9b can also be provided.
- 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.
