重量が大幅に増して慣性力が大きくなる問題があった。In the conventional electromagnetic metering valve as disclosed in JP-A-58-197466, the attractive force acts between the magnetic pole face of the iron core and the end face of the armature, and the attraction force acts between the armature sliding hole of the valve casing and the armature sliding hole. The force between the two parts does not work in a balanced manner, so if you try to increase the suction force to shorten the response time of the valve, you will have to increase the diameter of the armature and increase the area of the suction part, which will increase the weight of the armature. There was a problem in that the inertia force increased significantly.

路２７を通って、分配器２７の作動室２９に入る。When an exciting current is supplied to the winding 3 from a control device (not shown), magnetic flux flows as shown by the dotted line, and the end face of the armature 5 facing the planar magnetic pole face 9 of the iron core 7 and the valve casing 1 A force acts on the conical pole piece 11 facing the conical pole face 12 in a direction that reduces electromagnetic energy. Due to this attractive force, the armature 5 moves toward the iron core 7 against the closing spring 22, and the conical valve 10 connected to the armature 'f-5 is separated from the valve seat body 13 to be in an open state. Therefore, the fuel passes through the outlet 25, the fuel inlet 9, the annular chamber 20, and the conical valve 10.
It passes through the horizontal hole 17 and the vertical hole 18 and flows out at the orifice 21. This fuel is further supplied to the fuel inlet 26. Through the fuel inlet passage 27 it enters the working chamber 29 of the distributor 27.

。Next, the iron core 7 having a larger diameter than the iron core hole 33 of the flange 8 attached to the valve casing 1 is inserted into the flange 8 attached to the valve casing 1 until the flat magnetic pole surface 9 of the iron core 7 and the flat gauge surface 30 come into contact. Insert it into the core hole 33 with a force P and press-fit it into place. This press-fitted part of the iron core 7 guides the magnetic flux and is deformed below the elastic limit of the material of the iron core 7 as a magnetic flux guide portion 34. Fix the iron core 7 to the valve casing 1, and
It consists of a core fixing part 35 that deforms beyond the elastic limit of the material.

That's what I did. This reduces the weight of the armature 5, prevents the magnetic flux density from saturating by using a material with high magnetic flux density for the armature 5, increases the attractive force acting on the armature 5, and increases the attraction depending on the armature position. The force change can be made small.

9. An annular groove 40 is provided in the armature sliding hole 6, and the same cylindrical magnetic pole part 3
The magnetic flux passing through the cylindrical gap formed by the armature sliding hole 9 and the armature sliding hole 6 causes an attractive force to act. As a result, leakage magnetic flux between the planar magnetic pole portion 37 and the armature sliding hole 6 can be used as an attractive force.

加工を容易にすることができる。The difference from Fig. 4 is that the conical pole piece 11 is replaced by the cylindrical pole piece 41.
The magnetic flux passing through the cylindrical gap formed by the armature sliding hole 6 acts as an attractive force. This makes it possible to easily process the armature 5 without reducing the suction force too much.

Furthermore, since the distance between the two magnetic pole surfaces can be easily determined with high precision, there is less variation in valve response time between the electromagnetic metering valves, and the cost can be reduced.
