Definitions
- the invention is based on a fuel injector. It's already a Fuel injector known (DE 42 21 185 A1), in which the valve seat body through complex working processes is produced, which in addition to the relatively high material costs also leads to relatively high manufacturing costs.
- JP 07 063140 A discloses a fuel injection valve for internal combustion engines a valve housing, with a movable valve closing body, with a valve seat cooperates, which is formed on a valve seat body and downstream in a Outflow opening passes over, the valve seat body consisting of sheet metal passing through Deep-drawn shape has and a seat body bottom and a seat body ring edge has, the valve seat on an upper facing the seat body ring edge Bottom surface of the seat body floor is formed.
- valve seat body saves material is simple to manufacture and thereby an important one, especially in large series production Cost savings leads.
- the design of the valve seat body made of sheet metal not only leads to easy workability and a light weight of the valve seat body, but also a reduction in material requirements.
- Embodiments of the invention are in the drawing shown in simplified form and in the following Description explained in more detail.
- 1 shows a first Embodiment of the invention using a schematic fuel injector shown in partial representation
- Figure 2 shows a second embodiment of the invention partial representation of a fuel injector.
- FIG. 1 An example of one is already shown in FIG. 1 known fuel injector for Fuel injection systems from mixture compressors partially ignited internal combustion engines partially shown, the first embodiment according to the invention is trained.
- the fuel injector has one tubular valve housing 1, in which concentric to a Longitudinal valve axis 2, a longitudinal opening 3 is formed.
- a longitudinal opening 3 In the longitudinal opening 3 is, for example, rod-shaped Valve needle 5 arranged, its downstream end as Ball section is formed as a valve closing body 7 serves.
- the fuel injector is actuated in known way, for example, electromagnetic.
- a Solenoid 10 for axial movement of the valve needle 5 and thus for opening against the spring force of a not shown
- Return spring or closing of the fuel injector serves an indicated electromagnetic circuit with a Solenoid 10, an armature 11 and a core 12.
- the armature 11 is with the end facing away from the valve closing body 7 the valve needle 5 by z. B. connected a weld and aligned with the core 12.
- valve seat body 16th is downstream lying end of the valve housing 1 facing away from the core 12 in the concentric to the longitudinal axis 2 of the valve Longitudinal opening 3 inserted.
- the valve seat body 16 has a pot shape and has a seat bottom 19 which is transverse to the valve longitudinal axis 2, and one in the direction the seat body ring edge 20 extending the longitudinal axis 2 of the valve on.
- Valve seat 24 In an upper floor surface 21 of the seat body floor 19, which faces the edge of the seat body ring 20 is a Valve seat 24 is formed, in the flow direction downstream a penetrating the seat body floor 19 Outflow opening 25 connects.
- the valve seat 24 the valve closing body 7 together by closed valve is applied to the valve seat 24 and at open valve is lifted from this. Is formed the valve seat 24 from the cutting edge between the upper Bottom surface 21 and the outflow opening 25.
- the with the Valve closing body 7 cooperating width Valve seat area 24 is approximately 0.05 mm to 0.1 mm for example by lapping with a tool Sphere or cone generated.
- the diameter of the Outflow opening 25 is approximately 0.8 mm to 1.5 mm.
- valve seat body 16 is made of an approx. 0.8 mm to 1.5 mm thick sheet of stainless steel, for example Steel, by punching and deep drawing and then hardened.
- the circumference of the edge of the seat body ring 20 has a slightly smaller diameter than that Longitudinal opening 3 of the valve housing 1, so that the Valve seat body 16 inserted into the longitudinal opening 3 can be.
- a Spray plate 34 On a rim 20 facing away from the seat body ring lower floor surface 31 of the seat body floor 19 is a Spray plate 34, which in the embodiment 1 is cup-shaped and one on the lower bottom surface 31 has adjacent bottom part 35, the by means of a circumferential bottom weld seam 36 with the Seat body floor 19 is connected.
- the bottom part 35 of the spray plate 34 at least one spray hole 39, for example four formed by eroding or stamping Spray holes 39 on.
- a circumferential holding edge 40 which is in extends axially away from the valve seat body 16 and bent conically outwards up to its end 41 is. Since the circumferential diameter of the valve seat body 16 smaller than the diameter of the longitudinal opening 3 of the Valve housing 1 is only between the longitudinal opening and the slightly tapered outwardly curved retaining edge 40 of the Spray plate 34 a radial pressure.
- the Insertion depth of the valve seat body 16 and cup-shaped Spray plate 34 existing valve seat part in the Longitudinal opening 3 determines the default stroke Valve needle 5, since the one end position of the valve needle 5 at non-excited solenoid 10 by the system of Valve closing body 7 on the valve seat surface 24 of the Valve seat body 16 is fixed.
- the other end position the valve needle 5 is when the solenoid 10 is excited for example by the anchor 11 resting against the core 12 fixed.
- the path between these two end positions Valve needle 5 thus represents the stroke.
- a support ring 49 On a lower one facing away from the valve seat body 16 End face 46 of spray plate 34 is a support ring 49 with a support surface 50 on one to Valve seat body 16 bent support edge 51 of the Support ring 49 is formed. Between the levels Spray plate 34 and the support ring 49 is a sealing ring 54 arranged. On the valve seat body 16 facing away Side of the support ring 49 is on the valve housing 1 Flare 55 provided that a force on the support ring 49 exerts towards the valve housing edge 45, whereby the Support ring 49, the valve seat body 16 and the guide washer 15 presses against the valve housing edge 45 and thus in this Fixed location.
