Description
Technical field
The present invention relates to a kind of according to independent claims 1 electromagnetic valve as described in the preamble.
Background technology
Fig. 1 shows a kind of conventional electromagnetic valve, and especially for the electromagnetic valve of hydraulic efficiency gear, this hydraulic efficiency gear for example is used in antiblock device (ABS) or anti-slip regulation (ASR system) or the electronic stability program system (ESP system).As seen in Figure 1, for example be designed to that dead electricity opens that this routine electromagnetic valve 1 of type control cock comprises spool 5 ' and for generation of the electromagnetic assembly 2 of magnetic flux, this electromagnetic assembly 2 comprises housing cover 2.1, winding support 2.2, coil winding 2.3 and protective cover 2.4, the valve inserts 22 that this spool comprises shell 5.1, be connected by tight weld section 4 with this shell, with armature 6 and the retracing spring 8 of the first closing element 7 ' that is designed to tappet.Electromagnetic assembly 2 produces electromagnetic forcees, but this electromagnetic force makes the armature 6 with the longitudinal movement of the first closing element 7 ' that is designed to tappet overcome the power of retracing spring 8 towards 22 motions of valve inserts.The coil winding 2.3 that is wound on the winding support 2.2 consists of electric coil, and this electric coil can be by electric connection 2.5 energisings.The magnetic flux that 22 guiding of valve inserts are introduced by protective cover 2.4 by electromagnetic assembly 2 passes through air gap 3 vertically towards the direction of armature 6.By giving coil winding 2.3 energisings via electric connection 2.5 and passing through consequent magnetic flux, armature 6 overcomes the power of retracing spring 8 towards 22 motions of valve inserts.
In addition, valve inserts 22 holds so-called valve body 10 ', this valve body comprises main valve seat 12 ', and the first closing element 7 ' that is designed to tappet sinks in this main valve seat with sealing means by the primary seal element 7.1 ' that is designed to seal spherical crown, to realize the sealing function of electromagnetic valve 1.In order to utilize fluid block 18 to carry out packing in packing zone 18.1, form packing flange 9 at valve inserts 22.As can be seen from Figure 1, traditional electrical magnet valve 1 comprises the boiler check valve 30 of eccentric setting, and this boiler check valve is carried out directed through-flow function.As major part, the boiler check valve 30 of traditional electrical magnet valve 1 comprises movable packing element 32, is arranged on seal receptacle 34 and travel limit member or block in the non-return valve seat support 31, the trip limited part or block here are made of flat filter 33, to limit the range of movable packing element 32.Boiler check valve 30 with respect to valve spindle axis 1.1 eccentric settings is generally spheroid-conulite form, that is to say that packing element 32 is designed to spheroid, and the seal receptacle 34 that is arranged in the non-return valve seat support 31 has the conulite shape.The non-return valve seat support that is designed to plastic insert 31 of conulite 34 is in addition also for fluid block on every side 18 being sealed, be used for to valve body 10 ' sealing and for support annular filter 35 and flat filter 33.
In addition, a kind of electromagnetic valve with boiler check valve has been described in European patent application EP 1 101 678 A1.Described electromagnetic valve comprises: be arranged on the main valve between fluid inlet and the fluid egress point, this main valve has primary seal element and the main valve seat that is arranged in the valve body; With the boiler check valve that arranges with main valve axis coaxle ground in the bypass of main valve, this boiler check valve has packing element and valve seat.This valve seat is arranged in the valve member that is designed to plastic insert, and in this valve member, packing element is contained in the reentrant cylindrical cavity.Valve member also be used in addition to around the fluid means sealing, be used for sealing and being used for supporting annular filter and flat filter at valve body.
Summary of the invention
Relative therewith, the electromagnetic valve according to the present invention with feature of independent claims 1 has following advantage, and namely valve body is designed to sleeve, and the packing element of boiler check valve can be directed in this sleeve with axial motion.Main valve seat with through hole be arranged on the hood-shaped end of valve body sleeve, and the packing element of boiler check valve hermetically with the valve seat combined action, this valve seat is made of the edge of the valve body sleeve that opens wide at this end.
