Definitions
- the invention relates to a solenoid valve with adjustable armature stroke, in particular for a Injection valve of an internal combustion engine, and a method for adjusting the Anchor hubs according to the preamble of the independent claims.
- Fuel injectors with an actuatable by a nozzle needle Einspitzventil have a solenoid valve to trigger a lifting movement of the nozzle needle.
- a sleeve-shaped solenoid valve housing by means of a clamping nut with a Injector body of the injection valve connected, wherein the stroke of the solenoid valve via Spacers, which are inserted between housing and injector body, is set.
- Embodiment for forming the deformable element is the metal sleeve of the Housing provided with a weakening area, with which the elastic and optionally plastic deformation by applying a corresponding Tightening torque of the clamping nut is achieved.
- Another embodiment is that in the end face region of the metal sleeve of the housing, which of the shim assigns to the injector, a kind of biting edge is formed, the required Elasticity of the metal sleeve of the housing forms on the end face.
- the proposed Procedure always, first always by inserting a dial Presetting measure for the armature stroke make. By tightening the clamping nut is then by appropriate choice of the tightening torque of the armature stroke of the Electromagnet set. By an appropriate device can during the Tightening the clamping nut to measure the stroke of the electromagnet.
- the solenoid valve according to the invention with the characterizing features of Claim 1 has the advantage that for adjusting the armature stroke of the solenoid valve no Spacers or shims must be kept. This will both the manufacturing cost and the assembly costs for the production of Fuel injectors reduced.
- the section of the fuel injector 10 shown in FIG. 1 has a Injector 11 with a valve piece 12 in which a valve piston 13 is guided.
- the valve piston 13 acts at one end on a valve needle, not shown, in in a known manner cooperates with injection openings of the fuel injector.
- the valve piston 13 serves to actuate the valve needle in the closed position, the in turn constantly exposed to an acting in the opening direction of high fuel pressure is, which is supplied via a fuel port 14.
- valve bore 15 is from the front side of the Valve piston 13 includes a control pressure chamber 16, which has a Outlet throttle bore 17 to a spherical closing body 18 of the Control pressure chamber 16 relieving control valve leads.
- a Valve seat 19 is formed for the closing body 18.
- the fuel injector 10 further includes a solenoid valve 20 having a Electromagnet 21, a valve spring 22 and one of an anchor plate 23 and a Anchor bolt 24 existing anchors.
- the solenoid valve 20 also has a sleeve-shaped solenoid valve housing 26 which surrounds the electromagnet 21 and in a receptacle 25 of the injector 11 is received.
- the injector housing 11 In the area of Injector body 11 enclosing the solenoid valve housing 26 is the injector housing 11 provided with an external thread 27.
- the solenoid valve housing 26 is supported in the Recording 25 in the injector 11 on a spacer ring 30 from.
- a sealing ring 32 Between the Housing wall of the receptacle 25 of the injector 11 and the sleeve-shaped Solenoid valve housing 26 is positioned according to Figure 2, a sealing ring 32.
- the Solenoid valve housing 26 is also designed with a circumferential stop surface 28, on the one designed as a union nut clamping nut 29 acts. By Screwing the union nut 29 on the external thread 27 of the injector 11th engages the union nut 29 on the stop surface 28 of the solenoid valve housing 26, so that the solenoid valve 20 with the injector 11 of the fuel injector 10th is connected while the solenoid valve housing 26 is pressed onto the spacer ring 30 becomes.
- an elastically deformable metallic hollow ring is used, Such metallic hollow rings are also referred to as Wills rings.
- the Metallic hollow ring can be filled with a fluid, in particular gas or with an opening 31 or a circumferential slot to the cavity of the Apply hollow ring with the pressure of a surrounding medium.
- the distance ring 30 is the spacer ring 30 in the low pressure range.
- Essential for the present invention it is that the spacer ring 30 is elastically deformable, wherein the deformation is also a Share plastic deformation may have.
- Distance ring 30 use one or more shims as a spacer, the specify or specify a certain amount for the required armature stroke, and only a fine adjustment by the elastic deformation of the spacer ring 30th he follows.
