A device for adjusting an armature stroke of an armature upon actuation of a magnet of an electromagnetic valve having a stop bush disposed in an axial guide relative to a main body of the electromagnetic valve and adjustable in its axial position relative to the main body of the electromagnetic val
A device for adjusting an armature stroke of an armature upon actuation of a magnet of an electromagnetic valve having a stop bush disposed in an axial guide relative to a main body of the electromagnetic valve and adjustable in its axial position relative to the main body of the electromagnetic valve, which stop bush forms a stop for limiting the armature stroke in an axial direction. A variable adjusting element with two threaded portions providing a variable thread pitch (P) and the same thread direction by which the position of the stop bush is adjustable. The first threaded portion engages a corresponding first threaded portion of the stop bush, and the second threaded portion engages a corresponding second threaded portion of the main body, and to an electromagnetic valve having a corresponding device, in particular for use in a fuel injector.

What is claimed is: 1. A device for adjusting an armature stroke of an armature (3) upon actuation of a magnet (11) of an electromagnetic valve (1), the device comprising a stop bush (4) disposed in an axial guide (10) relative to a main body (2) of the electromagnetic valve (1) and being adjustabl
What is claimed is: 1. A device for adjusting an armature stroke of an armature (3) upon actuation of a magnet (11) of an electromagnetic valve (1), the device comprising a stop bush (4) disposed in an axial guide (10) relative to a main body (2) of the electromagnetic valve (1) and being adjustable in its axial position relative to the main body ( 2) of the electromagnetic valve, the stop bush forming a stop for limiting the armature stroke in an axial direction, a variable adjusting element (5) for adjusting the position of the stop bush (2), the adjusting element (5) having two threaded portions (6, 7) providing a variable thread pitch (P) and the same thread direction, and a first threaded portion (8) on the stop bush (4 ) and a second threaded portion (9) on the main body (2), the first threaded portion (6 ) engaging and corresponding to the first threaded portion (8), and the second threaded portion (7) engaging and corresponding to the second threaded portion (9). 2. The device of claim 1, wherein the magnet (11) of the electromagnetic valve (1) is disposed essentially around the stop bush (4). 3. The device of claim 1, wherein the magnet (11) of the electromagnetic valve (1) is disposed essentially in the stop bush (4). 4. The device of claim 1, wherein the axial guide (10) is disposed in the magnet (11). 5. The device of claim 2, wherein the axial guide (10) is disposed in the magnet (11). 6. The device of claim 3, wherein the axial guide (10) is disposed in the magnet (11). 7. The device of claim 1, wherein the axial guide (10) is disposed in the main body (2). 8. The device of claim 2, wherein the axial guide (10) is disposed in the main body (2). 9. The device of claim 3, wherein the axial guide (10) is disposed in the main body (2). 10. The device of claim 1, wherein the axial guide (10) is formed by at least one recess (12), in which a corresponding protrusion (13) of the stop bush (4) is guided. 11. The device of claim 2, wherein the axial guide (10) is formed by at least one recess (12), in which a corresponding protrusion (13) of the stop bush (4) is guided. 12. The device of claim 3, wherein the axial guide (10) is formed by at least one recess (12), in which a corresponding protrusion (13) of the stop bush (4) is guided. 13. The device of claim 1, wherein the axial guide (10) is formed by at least one flattened region (14), on which a correspondingly flattened region (15) of the stop bush (4) is guided. 14. The device of claim 2, wherein the axial guide (10) is formed by at least one flattened region (14), on which a correspondingly flattened region (15) of the stop bush (4) is guided. 15. The device of claim 1, further comprising a remanent air gap adjusting disk (16), which by its thickness determines the remanent air gap between the magnet (11) and the armature (4 ). 16. The device of claim 3, wherein the stop bush (4) a magnet bush (17). 17. The device of claim 3, wherein the adjusting element ( 5) is a magnet clamping nut (21). 18. The device of claim 1, wherein the difference between the pitches (P) of the two threaded portions (6, 7) is in the range from 0.02 to 0.10, and preferably is at a value of 0.05. 19. An electromagnetic valve (1) for use in a fuel injector, which has a magnet (11) and an armature (3), further having an adjusting for adjusting an armature stroke of the armature (3) upon actuation of a magnet (11) of an electromagnetic valve (1), the adjusting device comprising a stop bush (4), disposed in an axial guide (10) relative to a main body (2) of the electromagnetic valve (1) and adjustable in its axial position relative to the main body (2) of the electromagnetic valve, which stop bush forms a stop for limiting the armature stroke in an axial direction, wherein an variable adjusting element (5) with two threaded portions (6, 7), a variable thread pitch (P) and the same thread direction on the adjusting element (5) by which the position of the stop bush (4) is adjustable; and wherein the first threaded portion (6) engages a corresponding first threaded portion (8) of the stop bush (4 ), and the second threaded portion (7) engages a corresponding second threaded portion (9) of the main body (2).
