21 gap W is set as same with the thickness T-phase of the frame portion 44 of gasket 40.In other words, power is sandwiched in solenoid valve 30 and relay valve 21
When becoming larger, the thickness T of the frame portion 44 of gasket 40 is compressed.
In addition, stream of the relay valve connector 22 of the solenoid valve connector 32 of solenoid valve 30 and relay valve 21 by gasket 40
Road forming portion 42 is connected to.In solenoid valve 30 and relay valve 21 when sandwiching power and becoming larger, the flow path forming portion 42 of gasket 40 is compressed.
In addition, solenoid valve 30 end face and relay valve 21 end face, in addition to edge, solenoid valve connector 32 and in
Part except valve connector 22, from 30 side of solenoid valve, successively there are solenoid valve side space 43a, plate portion 45, relay valve sides

In addition, compressed air may be certainly when generating blocking due to foreign matter in the flow path of solenoid valve 30 or relay valve 21
Solenoid valve connector 32, relay valve connector 22 or flow path forming portion 42 are empty to solenoid valve side space 43a and relay valve side
Between 43b flow into.At the time of such, compressed air is discharged the interconnecting part 47 for being set to the frame portion 44 of gasket 40 certainly to outside.
Therefore, it can prevent from flowing due to compressed air to the solenoid valve side space 43a and relay valve side space 43b for being set to gasket 40
Enter and applies excessive load to frame portion 44.
So, the vibration attenuating space 43 that is surrounded by frame portion 44 is formed by gasket 40, can be arranged gasket 40 with
The part that the end face of solenoid valve 30 and the end face of relay valve 21 are not directly contacted with.Therefore, even if solenoid valve 30 and relay valve 21
The power that sandwiches become larger, be also able to suppress the propagation from the vibration that solenoid valve 30 generates to relay valve 21.
As described above, effect below can be obtained according to the present embodiment.
(1) when gasket 40 is set between solenoid valve 30 and relay valve 21, solenoid valve connector 32 and relay valve connector
It is connected between 22 using flow path forming portion 42 and forms flow path 41.Further, since frame portion 44 is sandwiched in solenoid valve 30 and relay valve
Between 21, solenoid valve 30 is not directly contacted with relay valve 21, therefore the vibration generated by solenoid valve 30 is not directly to relay valve 21
Transmitting.Therefore, because vibration attenuating space 43 be present between solenoid valve 30 and relay valve 21, therefore attempt from solenoid valve 30 to
The vibration that relay valve 21 is propagated is vibrated herein to decay in attenuating space 43.As a result, it is possible to inhibit vibration from solenoid valve 30 in
After the propagation of valve 21.Even if due to sandwiching between solenoid valve 30 and relay valve 21 power becomes larger and frame portion 44 is crushed, also formed
This vibration attenuating space 43, therefore even if strongly fasten solenoid valve 30 and relay valve 21 in order to ensure sealing surface pressure
In the case where, it can also be reliably suppressed the propagation of vibration.
(2) also the vibration generated by solenoid valve 30 can be made to decay using plate portion 45.
(3) power is sandwiched when even if being arranged and sandwich between solenoid valve 30 and relay valve 21 to become larger, pass through the prominent of plate portion 45
46 are played to contact with solenoid valve 30, relay valve 21 and ensure between other positions and solenoid valve 30, relay valve 21 in plate portion 45
Attenuating space 43 is vibrated, therefore is able to maintain that the effect of vibration attenuating space 43.
(4) the vibration attenuating space 43 of gasket 40 is that boundary is divided into solenoid valve side space 43a and relay valve side with plate portion 45
Space 43b.The vibration generated as a result, by solenoid valve 30 decays in solenoid valve side space 43a first.It then attempts to from solenoid valve
The vibration that side space 43a is propagated to relay valve side space 43b, such as sound are shielded using plate portion 45.In addition, even if vibration is saturating
Plate portion 45 is crossed, the vibration of the transmission further decays in relay valve side space 43b.Therefore, it can further suppress by solenoid valve
Propagation of 30 vibrations generated to relay valve 21.
It (5) can will be due to the deterioration of flow path forming portion 42, the deterioration of the surface roughness of hermetic unit or foreign matter
Attachment etc. and compressed air from flow path forming portion 42 to vibration attenuating space 43 that leak from are by interconnecting part 47 to the outer of frame portion 44
Side discharge.Therefore, can prevent following situations: due to the compressed air to the vibration leakage of attenuating space 43, frame portion 44 is deformed,
Solenoid valve 30 is loosened relative to the fixed of relay valve 21.In addition, the compressed air leaked from flow path forming portion 42 is from interconnecting part 47
Discharge, so as to confirm the leakage of compressed air.
In addition, above embodiment also can by suitably changed it is below in a manner of implement.
In said structure, limit can also be set in a part of the end face of the solenoid valve 30 opposite with relay valve 21
Portion processed, the limiting unit limit the excessive flattening of gasket 40 by contacting with relay valve 21.According to this structure, can press down
The excessive flattening of gasket 40 can be avoided since 42 breakage of flow path forming portion leads to the premature loss of sealing performance, simultaneously
Inhibit propagation of the vibration from solenoid valve 30 to relay valve 21.For example, as shown in figure 5, limiting unit 37 be set to solenoid valve 30 with
A part (end 36) of the opposite opposite face 35 of relay valve 21, and be only arranged at rectangular shape end 36 4 sides in two
A side.The height H away from opposite face 35 of limiting unit 37 is set as (H < T) smaller than the thickness T of gasket 40.The contact of limiting unit 37
Position is preferably disposed to for solenoid valve 30 being fastened and fixed near the screw 31 of relay valve 21.In addition the contact area of limiting unit 37
It is preferred that contact area is smaller within a few percent of the area of opposite face 35, more it is able to suppress and vibrates from solenoid valve 30 in
After the propagation of valve 21.In addition, the setting position of limiting unit and size can be changed arbitrarily.For example, it is also possible to expand solenoid valve
Limiting unit is arranged in 30 opposite face 35.It is set in addition it is also possible to avoid 40 ground of gasket in the inside of the opposite face 35 of solenoid valve 30
Set limiting unit.
In said structure, limit can also be set in a part of the end face of the relay valve 21 opposite with solenoid valve 30
Portion processed, the limiting unit limit the excessive flattening of gasket 40 by contacting with solenoid valve 30.The height of limiting unit is set as comparing
The thickness of gasket 40 is small.According to this structure, it is able to suppress the excessive flattening of gasket 40, can be avoided since flow path is formed
42 breakage of portion leads to the premature loss of sealing performance, while inhibiting to vibrate the propagation from solenoid valve 30 to relay valve 21.In addition, limit
The setting position in portion processed and size can be changed arbitrarily.For example, it is also possible to expand the opposite face of relay valve 21 limitation is arranged
Portion.In addition it is also possible to avoid setting limiting unit in 40 ground of gasket on the inside of the opposite face of relay valve 21.
In addition it is also possible to a part setting limiting unit in the end face of the solenoid valve 30 opposite with relay valve 21, simultaneously
A part setting limiting unit in the end face of the relay valve 21 opposite with solenoid valve 30.
In the above-described embodiment, although each face in the plate portion 45 of gasket 40 has 6 protrusions 46, as long as energy
Position other than the protrusion 46 in enough suppressing plate portions 45 is attached at solenoid valve 30 or relay valve 21, protrusion 46 can also be set as 1
It is a 5 or less or 7 or more above.
In the above-described embodiment, although the same position in the two sides in the plate portion 45 of gasket 40 is provided with protrusion 46,
But protrusion 46 can also be set in different positions.
It in the above-described embodiment, can also be with although the two sides in the plate portion 45 of gasket 40 is provided with protrusion 46
Only protrusion 46 is arranged in the single side in plate portion 45.
In the above-described embodiment, although in the plate portion 45 of gasket 40 there is hemispherical protrusion 46 to be used as thick wall portion,
But the shape of the protrusion as thick wall portion is not limited to hemispherical, also can be set to the others of cylindric, polygonal column etc.
Shape.In addition, can also have raised line in the plate portion 45 of gasket 40 as thick wall portion.
In the above-described embodiment, plate portion 45 is set as to divide the vibration attenuating space 43 of gasket 40 for solenoid valve side space
43a and relay valve side space 43b.Vibration attenuating space 43 is not divided but it is also possible to be set as plate portion 45 for solenoid valve side space
43a and relay valve side space 43b.
For example, as shown in fig. 6, can also be so that by gasket 40 in a manner of the plate portion 45 of gasket 40 be contacted with relay valve 21
Plate portion 45 is integrally formed with frame portion 44 and flow path forming portion 42.Even such structure, the vibration generated by solenoid valve 30
It is dynamic to decay first in solenoid valve side space 43a.It then attempts to from the vibration that solenoid valve side space 43a is propagated, such as sound, benefit
It is shielded with plate portion 45.Therefore, it is able to suppress the propagation from the vibration that solenoid valve 30 generates to relay valve 21.
In addition, as shown in fig. 7, can also be so that by gasket 40 in a manner of the plate portion 45 of gasket 40 be contacted with solenoid valve 30
Plate portion 45 is integrally formed with frame portion 44 and flow path forming portion 42.Even such structure, the vibration generated by solenoid valve 30
It is dynamic to be shielded first with plate portion 45.In addition, even if vibration transmitting plate portion 45, the vibration of the transmission, such as sound, further in
