A kind of Valve EGR that the utility model is provided, it include valve body, the spool being located in valve body, are wound in spool
On solenoid, secured core, armature, the valve gap for making spring that armature resets and coordinate with valve body, spool tool
Endoporus, secured core and armature is had to be located in the endoporus, the valve body has the inlet channel of connection canister, and the valve gap has
The outlet passageway of connection motor intake manifold, the contact jaw that the outlet passageway is coordinated with armature are fillet.
It is preferred that the radius of corner scope is between 0.03 millimeter to 0.23 millimeter.
It is preferred that the spool both ends of the surface are provided with the first magnetic conduction sheet, spool two sides have the second magnetic conduction sheet, the first magnetic conduction
Piece and the second magnetic conduction sheet cooperate and enclose around spool.
It is preferred that first magnetic conduction sheet is provided with hole corresponding with the endoporus of spool, secured core one end is located in the hole,
The other end is stretched in the endoporus of spool.
It is preferred that described armature one end is provided with the sealing gasket coordinated for sealing outlet passageway with contact jaw.
It is preferred that the valve body has interface, spool is fixed in electric mortiser piece one end, and the other end is located in the interface of valve body.
Compared with prior art, as the contact jaw that the outlet passageway is coordinated with armature is fillet, that is to say, that contact
End is with armature close to linear sealing, using the teaching of the invention it is possible to provide better seal performance.
