Description
Technical field
The present invention relates to a kind of solenoid valves as described in the preamble according to claim 1.In addition, the present invention relates to one kind
Fuel injector with solenoid valve according to the present invention.
Background technique
According to claim 1, the solenoid valve of preamble is as known to 10 2,011 078 346A1 of DE of the applicant.?
The solenoid valve known for controlling liquid flow within the fuel injector.The spray of fuel injector can be influenced by the control of liquid flow
The opening and closing campaign of mouth needle, and therefore influence the fuel quantity being ejected into the combustion chamber of internal combustion engine.For this purpose, solenoid valve has
There is electromagnet, the electromagnet has and the coefficient electromagnet armature of the electromagnet.The electromagnet armature is on its longitudinal axis
With through hole, armature pin is extend into the through hole.Electromagnet armature can be moved and be borrowed along the longitudinal direction in armature pin
It helps compression spring to resist the magnetic force acted on when electromagnet is powered to be loaded by the direction force of electromagnet towards valve seat.
(system) pressure present in this solenoid valve or fuel injector is typically larger than 1500bar, is especially greater than
2000bar.For axial movement of the electromagnet armature in armature pin, it is desirable that there are small between electromagnet armature and armature pin
(radial) guiding clearance.The guiding clearance not only and pressure in relation to and with temperature it is related.When pressure or temperature increase
There is the increase of the through hole in electromagnet armature and the radially-directed gap between armature pin.The increase or expansion in the guiding gap
On the one hand width is caused by the compression for being radially applied to armature pin, on the other hand by being equally radially applied to
The compression on through hole in electromagnet armature causes.Additionally, the bulking effect of material also works when the temperature rises.?
Increased radially-directed gap leads to the leakage towards solenoid valve area of low pressure direction between through hole in armature pin and solenoid valve
Amount increases, and system pressure is higher, then the leakage rate is bigger.Because leakage rate increase, which is equal to, has the bigger proportion of goods damageds, should
The proportion of goods damageds must be compensated within the fuel injector by fuel transfer pump, so making to reveal minimization of loss to be to be worth pursuing.
Summary of the invention
Solenoid valve with claim 1 feature has the advantage that the solenoid valve between electromagnet armature and armature pin
Leakage rate in the region of guide part and existing pressure and/or temperature are independently also less always under high system pressure.
The idea that the present invention is based on is, the structure of electromagnet armature is changed in this wise compared with the existing technology, so that electric
Magnetic armature is at least had bigger elasticity modulus to region in the region that it is used for the hole of armature pin and/or smaller thermal expansion is
Several materials radially, are i.e. surrounded in a manner of sleeve.In other words, which means that electromagnet armature is in the guiding for armature pin
Region in be made of two different materials, the material is disposed concentrically upon relative to each other.This causes, and in pressure rise or leads to
Leakage seam when often being increased along with the temperature of pressure rise, between the respective section in armature pin and electromagnet armature pilot hole
Gap reduces compared with being oriented to the broadening in gap in other words in the prior art without sleeve the case where, because of the pilot hole of electromagnet armature
Obstruction is radially expanded trend or reduces the expansion.
The advantageous extension scheme of solenoid valve according to the present invention is enumerated in the dependent claims.
Very particularly preferably, electromagnet armature is at least in its sleeve shaped section of composition for armature pin guide part by steel
It constitutes, also, the sleeve for radially surrounding in sleeve shaped section electromagnet armature is made of hard metal.Hard metal especially has following
Advantage: effect that the hard metal is nonmagnetic and the magnetic loop for therefore not influencing electromagnet armature.In addition, being made it possible to using hard metal
Connect sleeve not only can also by welding process by contraction process but also for example with electromagnet armature.Therefore, it is held in the mouth in electromagnetism
It can be realized bigger configuration possibility when the possible manufacture of iron or connection between sleeve and electromagnet armature.
As has already been discussed, the connection between electromagnet armature and sleeve connects more particularly to or by squeeze or shrink
It connects or is realized by being welded to connect.Alternatively, however, also, it is contemplated that electromagnet armature be configured to together with sleeve it is metal injection molded
Form (MIM, Metal Injection Moulding) component.Cancel in this configuration electromagnet armature and sleeve it
Between the manufacturing step that is attached.
Sleeve can pass through electromagnet armature in the effect that guiding clearance reduces form in pressure rise to electromagnet armature
The design of corresponding geometric dimension (is considering for sleeve and electromagnet armature between the wall thickness in sleeve section and sleeve wall thickness
In the case where material) it influences.The channel syndrome in the case where common size design and material (especially hard metal is used for sleeve)
Bright to be favorably, the wall thickness of sleeve shaped section and the wall thickness of sleeve are at least approximately equal.
Especially when axially engaging sleeve on the sleeve shaped section of electromagnet armature, in order to ensure or simply guarantee
The axial physical location of sleeve and advantageously, sleeve axially sticks on the stepped part of electromagnet armature.
The present invention also relates to a kind of fuel injectors using solenoid valve according to the present invention, wherein the fuel injection
