Definitions
- the invention relates to an injection valve of the type specified in the preamble of the first claim.
- the O-ring arranged on the mouthpiece of the injection valve is pressed radially when inserted into the receiving bore in the intake manifold wall.
- the receiving bore usually has a chamfer on the plug-in side, by means of which the pressing of the O-ring is initiated when it is inserted into the receiving bore.
- this chamfer is generally relatively low in the area around the receiving bore in the insertion direction and is formed at a relatively large cone angle. This results in a relatively sharp edge at the transition from the receiving bore into the chamfer, which can lead to damage to the O-ring if the mouthpiece of the injection nozzle is positioned off-center to the receiving bore.
- a plug arrangement with an interposed sealing ring is provided for decoupling the noise between the injection valves and the fuel distributor line, similar to the above-described intake manifold-side plug arrangement.
- each injection valve can be moved to a certain extent relative to the fuel distributor line, so that when the injection valves are installed at the same time, some have eccentric positions Injectors are to be expected in their mounting holes.
- the object of the present invention is to develop an injection valve of the generic type in such a way that damage to the sealing ring during assembly is excluded.
- the sealing ring is protected both in the time after the injection valve has been completed and until it is installed, and also during installation. The displacement of the sleeve and thus the release of the sealing ring is only achieved when the injector is installed.
- the development according to claim 2 describes an advantageous inner contour of the sleeve. This ensures that the sealing ring slides easily and without damage into the mounting hole when the injection valve is installed. On the other hand, this does not hinder the insertion of the injection valve.
- Another development of the invention according to claim 3 has the advantage that, without further aids, both a secure axial displacement of the sleeve is made possible and a secure hold in the time in which the sleeve is not installed is. In particular, no further aids such as adhesive strips, clips, etc. are required to use the sleeve as protection for the sealing ring until the injection valve is installed.
- the sleeve simultaneously takes over a centering function, so that the attachment of the injection valve, in particular if a plurality of injection valves are to be installed simultaneously, is greatly facilitated.
- FIG. 1 the front part of an injection valve 1 for a mixture-compressing internal combustion engine, not shown, is shown schematically. It carries on its front mouthpiece 2 a sealing ring 3, which is preferably designed as an O-ring. This is supported in the axial direction on a shoulder 4 and 4.1. The sealing ring 3 is enclosed by a sleeve 5 which is guided on a cylindrical section 6 of the injection valve 1.
- the injection valve 1 is inserted with its mouthpiece 2 into a wall opening 8 of the suction pipe 7, the mounting of the injection valve 1 essentially through the pressed sealing ring 3 between the wall opening 8 and the mouthpiece 2 is achieved.
- the wall opening or receiving bore 8 has a chamfer 9 on the insertion side.
- the sleeve 5 provided according to the invention has at its front end a conical outer contour 10 which merges into a cylindrical section 11.
- the cone angle is equal to twice the chamfer angle, so that the sleeve 5 can be used simultaneously for centering the injection valve 1 during the insertion process.
- the inner contour of the sleeve 5 consists of three sections, two cylindrical sections 12 and 13 and a conical section 14 being provided.
- the diameter of the cylindrical inner section 12 corresponds in diameter to the outer diameter of the cylindrical section 6 of the injection valve 1.
- the second cylindrical section 13 is smaller in diameter than the section 12. Its diameter corresponds approximately to the outer diameter of the sealing ring 3. However, it is slightly smaller, so that the sleeve 5 is securely held by the sealing ring 3 in the unassembled state and protects it against damage and contamination.
- the transition between the two cylindrical sections 12 and 13 is preferably crowned. This makes it easier to push the sleeve onto the injection valve.
- the smallest diameter of the cone is slightly smaller than the inside diameter of the wall opening 8. This ensures that the sealing ring 3 does not come into contact with the inner edge of the chamfer 9 when the injection valve 1 is inserted and is thereby damaged.
- the injector 1 is shown in its installed position.
- the injection valve 1 is displaced axially under slight pressure.
- the sealing ring 3 is squeezed by the conical section 14 while simultaneously axially pushing forward through the shoulder 4 into the wall opening 8. This holds the injection valve 1 and at the same time seals the wall opening 8.
- a further seal to the outside, mainly against dirt, is formed by the sleeve 5, which continues to be supported with its conical section 10 on the chamfer 9 in the installed state.
- the sleeve 5 When pulling out the injection valve 1, the sleeve 5 is pressed by hand against the chamfer 9. The sealing ring 3 is taken along by the shoulder 4.1 when it is pulled out and now slides back over the conical inner section 14 into the sleeve. Damage caused by the edges of the receiving bore or the chamfer 9 is therefore excluded.
- a radially arranged pin can be provided on the cylindrical section 6 of the injection valve, which leads the sleeve over an elongated hole.
