Property material is made.Via hole is used for passing through for valve body 118, is formed through the basal surface of joint member 120.Valve pocket 122 by
The upper end face of valve seat member 110 and the rear surface of joint member 120 are limited.
Constituting the electromagnetic component 80 of magnetic valve 10 includes：Generally cylindrical bobbin 132, hollow space 130 is formed therein；
Magnet coil 134, it is wrapped on bobbin 132；And slide core 116 and stationary core 138 (the first stationary core), both of which
It is made and is accommodated in the hollow space 130 of bobbin 132 by magnetic material.
The rear surface of bobbin 132 by the 3rd containment member 140 against tubular element 64 flange 84.In bobbin
Sealing is formed by the 3rd containment member 140 between 132 and tubular element 64.In addition, the larger diameter flange of joint member 120 is clipped in
Between the upper end face of the tubular portion 82 of bobbin 132 and tubular element 64.
Bobbin 132 is formed from a resin, and is incorporated in housing in the state of magnet coil 134 is wound about
142 inside.More particularly, the bottom of housing 142 is crimped around the upper end of valve body 22, due to this, housing 142
It is supported on together with bobbin 132 on valve body 22, the upper end of flange 84 and valve body 22 is covered by housing 142.
The low top surface for opening housing 142 of the upper end face of bobbin 132, annular 4th containment member 144 be arranged in this two
Between individual component.Sealing is formed by the 4th containment member 144 between bobbin 132 and housing 142.Outlet port 146 is formed
In a part for the side surface of housing 142.The connector 148 being integrally formed with bobbin 132 is protruded from outlet port 146.
The power supply terminal 150 electrically connected with magnet coil 134 is arranged in the inside of connector 148.
In the hollow space 130 of the upper end insertion bobbin 132 of stationary core 138 and slide core 116.In slide core 116
Rear surface on, valve body 118 is formed as protruding along the direction towards valve seat 114, and on its upper end face, columnar protrusions
154 are formed as protruding along the direction towards stationary core 138.
On the other hand, bottom spring reception hole 156 is formed in stationary core 138, and the second coil spring 158 is accommodated in spring
In reception hole 156.More particularly, the bottom of the second coil spring 158 is rested against on the upper end face of slide core 116, post
Shape projection 154 is inserted in its interior section.On the other hand, the upper end of the second coil spring 158 seats against spring reception hole 156
On top surface.Therefore, the second coil spring 158 is resiliently biased the valve sheet of slide core 116 along the direction towards the side of valve seat 114
Body 118.
Built in the above described manner substantially according to the magnetic valve 10 of the present embodiment.Next, the control of combination pressure fluid is set
Standby 12 operation provides the operation on magnetic valve 10 and the explanation of advantage.
Position and be fixed to by the way that valve body 22 to be inserted to the attachment hole 16 of engine main body 14, and by housing 142
Engine main body 14, pressure fluid control device 12 is attached to engine main body 14.Now, attachment hole 16 is by the first containment member
44 sealings.
If electric current is not supplied to magnet coil 134, then do not generate magnetic field in magnet coil 134.Therefore, attraction
It will not be acted on based on magnetic force on slide core 116.On the other hand, due to the second coil spring 158, elastic force acts on slide core
On 116.By this elastic force, slide core 116 is pressed down on towards the side of valve seat member 110.As a result, valve body 118 is rested against
On valve seat 114.More particularly, magnetic valve 10 is in valve closed mode.
When magnetic valve 10 is in valve closed mode, the elasticity applied by the second coil spring 158 to slide core 116 is inclined
Power is put, slide core 116 is resiliently biased towards the side of valve seat member 110.As a result, the valve body 118 of slide core 116 is rested against
On valve seat 114, and the connection between valve opening 112 and valve pocket 122 is cut-off.
On the other hand, first guide cavity 68 connects release port 34 by flow path, and flow path is by forming in bobbin 50
Aperture 66, pressure fluid release flow path 54 and transverse holes 60 in projection 62 are constituted.Therefore, first guide cavity 68 becomes to have
With the identical pressure of release port 34.
Now, first coil spring 70 applies the pressure fluid exceeded to the elastic force of bobbin 50 inside first guide cavity 68 and applied
To the pressing force of bobbin 50.As a result, the upper end face of the projection 62 of bobbin 50 is in the rear surface 65 for abutting tubular element 64
Uppermost position in fig-ure.As a result, input port 30 is closed by the larger diameter side wall of bobbin 50, therefore, input port 30 and output port
Connection between 32 is cut off.On the other hand, output port 32 and release port 34 are by being formed in the first annular He of recess 56
Flow path connection between reception hole 26.As a result, in the case where electric current is not supplied to magnet coil 134, from (not shown)
The pressure fluid of pressure fluid supply source supply is not introduced into the inside of valve body 22.
In contrast, when electric current by power supply terminal 150 supply to magnet coil 134 when, magnet coil 134,
In stationary core 138, especially magnetic force is generated in the flange 84 of tubular element 64 (the second stationary core).Because being caused by this magnetic force
Elastic force of the attraction more than the second coil spring 158, slide core 116 is attracted and shifts on the side towards stationary core 138 1.
As a result, valve body 118 is integratedly shifted with slide core 116 and separated from valve seat 114.More particularly, magnetic valve 10 is in
Open mode.
As that can be understood from the foregoing that, longitudinal direction displacement of the slide core 116 along valve body 22 and tubular portion 82.
As a result, the direction of the first pilot pressure input port 38 and the extension of the second pilot pressure input port 98 is approximately perpendicular to slide core
116 direction of displacement.In addition, the upper end of slide core 116 is inserted under the hollow space 130 of bobbin 132, slide core 116
End is inserted by joint member 120 in the enlarged diameter section 106 (valve reception hole 88) of tubular element 64, during its displacement, living
The tubular element 64 and joint member 120 that dynamic core 116 is inserted by it are guided.
Now, pressure fluid is introduced from input port 30.Just as will be discussed later, because when bobbin 50 is shifted
When, the position of first annular recess 56 reaches the position corresponding to input port 30.In addition, the pressure introduced from input port 30
Fluid supplies flow path 42 from the first pilot pressure output port 36 by and through the first pilot pressure, in addition,
Through through after the first pilot pressure input port 38 and the second pilot pressure input port 98, reaching the small straight of valve reception hole 88
