The active force of spring 53, piston valve 5 are reinforced to from the direction that primary-valve port 12a leaves (valve opening position).Also, sealing 52 exists
Piston valve 5 closes primary-valve port 12a when being seated at main valve seat 12.In addition, being formed centrally within pilot port on sealing 52
5a and guiding path 5b, pilot port 5a are by guiding path 5b and valve port 12a conducting in secondary side connector 1B.In addition, guide
It is guide's valve seat 5a1 around the 5a of port.Also, it is provided with gap between piston valve 5 and cylinder body 1C, by the gap,
The fluid of side side connector 1A can flow into the back space of piston valve 5.
Electromagnetic drive part 2 has the plunger housing 21 of " shell " as cylindrical shape centered on axis L, insertion
The plunger 22 formed by magnetic substance in plunger housing 21, the attraction formed by magnetic substance for being fixed in 21 upper end of plunger housing
Part 23, the plunger spring 24 being configured between plunger 22 and attraction part 23, the line for utilizing resin material sealing (interior packet) cylindrical shape
The electromagnetic coil 25 of circle, the magnetic part, that is, iron plate outer container 26 chimeric with the periphery of electromagnetic coil 25.
Outer container 26 includes cup-shaped outer container 26A, peripheral part and the cup-shaped outer container 26A for constituting by magnetic substance and be in cup-shaped with the end
Opening integration the bottom plate outer container 26B formed by magnetic substance.Cup-shaped outer container 26A by tubular side surface part 26a and and cup-shaped
The corresponding top plate portion 26b in bottom constitute.Also, electromagnetic coil 25 is configured in cup-shaped outer container 26A, by the electromagnetic coil 25
In the state that conductor-retaining portion 25a is embedded in the rectangular slits portion 26c of bottom plate outer container 26B, bottom plate outer container 26B is embedded in outside cup-shaped
The opening portion of case 26A.Electromagnetic coil 25 is covered by cup-shaped outer container 26A and bottom plate outer container 26B as a result, and by top plate portion 26b and

Applying the identical element of mode is the structure for playing phase same-action, in the attached drawing in second embodiment and third embodiment
Same parts on mark and Fig. 1 the same symbol and suitably the repetitive description thereof will be omitted.
In this second embodiment, the place being different from the first embodiment is the coil guide part as " interconnecting piece "
6 structure and the aspect for not having elastomeric element 4.As shown in figure 5, coil guide part 6 will have elasticity and be formed by magnetic substance
Wire material be formed as coil spring shape on the direction axis L radially.The coil guide part 6, which has, is being installed on solenoid valve
The same-diameter portion 61 with the internal diameter smaller than the outer diameter of plunger 21 under natural conditions before is linked to the truncated cone of same-diameter portion 61
The rake 62 of shape.Also, same-diameter portion 61 is pressed into plunger as 25 side of electromagnetic coil by rake 62 by the coil guide part 6
The periphery of shell 21 is compressed in the mode parallel with the bottom plate outer container 26B of outer container 26 of rake 62 and is configured, with the bottom plate outer container
26B is abutted.The rake 62 is crimped on the bottom of outer container 26 by the elastic force in the direction axis L of itself in the assembled state
In plate outer container 26B.That is, in the state of being installed on solenoid valve, same-diameter portion 61 with plunger housing 21 is closely sealed contacts, rake 62 with
Bottom plate outer container 26B contact.
As more than, since coil guide part 6 is crimped on plunger housing 21 by the elastic force of same-diameter portion 61 and rake 62, because
The coil guide part 6 of this electrical connection outer container 26 and plunger 22 configures very closely relative to plunger 22.In addition, due to coil
The rake 62 of guide part 6 is crimped on the bottom plate outer container 26B of outer container 26, therefore will not be outside coil guide part 6 and bottom plate
Gap is generated between case 26B.Therefore, the coil guide part 6 formed by the outer container 26 by being formed by magnetic substance and by magnetic substance
The efficiency of magnetic loop that generates of the magnetic line of force get higher, the electrical current of electromagnetic coil 25 can be reduced and reduce electromagnetic coil 25
Temperature rises.
