In the conventional variable solenoid valve, the magnetic path is formed by a separate pole, and the housing is provided for the purpose of simply embedding the pole, the electromagnetic generator, and the armature. As a result, a space may be generated between the pawl and the housing, and as a result, an error may occur not only in the applied electromagnetic force, but also in the linear movement path (distance) of the armature. However, according to the present invention, since the magnetic path is formed only by the pole cover 200, and the armature 300 linearly moves by the magnetic path formed by the pole cover 200, an error may be caused.

Is omitted.

The flange body 1410 is one side of the axial direction is inserted into the electromagnetic generating unit 1800, a plurality of the flow path (1450) is formed on the outer peripheral surface of the hollow formed so that the spool 1600 can linearly reciprocate ( 1490).

The self-concentrating portion 1420 is formed to protrude in a conical shape along the axial direction from the end portion of the flange cover 1410 in the pole cover 1200, the armature receiving groove 1430 is formed in the center of the axis. That is, the self-concentrating portion 1420 is formed along the circumferential direction on the outer side of the amateur receiving groove 1430, and extends toward the pole cover 1200 to gradually decrease in outer diameter.

The coupling stopper 1440 is formed to protrude radially outward from the outer circumferential surface of the flange body 1410 so that the coupling stopper 1440 is fitted to the plate 1500.

In a conventional variable solenoid valve, a magnetic path is formed by a separate core, and the spool and the armature linearly move separate flanges. As a result, a space may be generated between the core and the flange, thereby causing an error in the applied electromagnetic force, as well as an error in the linear movement path of the spool and the armature. However, according to the present invention, since the core flap 1400 is formed only on the magnetic path, and the armature 1300 and the spool 1600 are linearly moved by the magnetic path formed by the core flange 1400, an error is caused. There is no space that can be made.

In addition, in the present invention, the fixing force between the core flange 1400 and the plate 1500 is improved by the coupling stopper 1440, the coupling rib 1540, and the caulking groove 1550, and the core seating portion The fixed coupling force between the plate 1500 and the housing 1100 is improved by the 1140 and the core coupler 1150.

When the coupling stopper 1440 of the core flange 1400 is coupled to the coupling rib 1540 in an interference fit manner, a fixed coupling force is increased. In addition, when the coupling stopper 1440 and the coupling unit 1520 are hermetically sealed through a caulking method through the caulking groove 1550, a fixed coupling force increases.

Therefore, according to the variable solenoid valve according to another embodiment of the present invention, by eliminating the gap between the core and the flange existing in the conventional variable solenoid valve to reduce the occurrence of errors, increase the electromagnetic force concentration effect, and enhance the coupling force There is.

Figure 12 shows a variable solenoid valve according to another embodiment of the present invention.
