In addition, relay valve connector 22 is equivalent to the fluid flow port of relay valve 21.
Gasket 40 is formed by the flexible single material such as synthetic rubber.Gasket 40 have will be set to solenoid valve 30 The flow path forming portion 42 that is connect with the relay valve connector 22 for being set to relay valve 21 of solenoid valve connector 32.Flow path forming portion 42 form stream between the solenoid valve connector 32 for being set to solenoid valve 30 and the relay valve connector 22 for being set to relay valve 21 Road 41.The incorporating section 32a of storage flow path forming portion 42 is equipped in the open edge of the solenoid valve connector 32 of solenoid valve 30.Storage Portion 32a is formed as the expanding open edge of solenoid valve connector 32.Each flow path forming portion 42 is cylindric, and is fitted into and is mounted on It is formed in the incorporating section 32a of the solenoid valve connector 32 of solenoid valve 30.
As shown in Figure 2 to 4, gasket 40 includes: the frame portion 44 being sandwiched between solenoid valve 30 and relay valve 21;And it sets It is placed in the inside of frame portion 44, will seal and formed between solenoid valve 30 and relay valve 21 and be connected to the solenoid valve connector of solenoid valve 30 32 with the flow path forming portion 42 of the flow path of the relay valve connector 22 of relay valve 21.This frame portion 44 is set throughout the periphery of gasket 40 It sets.The two sides of frame portion 44 is contacted with solenoid valve 30 and relay valve 21 respectively.In addition, gasket 40 is in frame portion 44 and flow path forming portion The vibration attenuating space 43 for the vibration decaying for making to be generated by solenoid valve 30 is formed between 42.Therefore, as shown in Figure 1, vibration decaying Space 43 is from the end face (with also referred to as of the inner wall 44a of frame portion 44, the outside wall surface 42a of flow path forming portion 42, solenoid valve 30 Face), the space that surrounds of the end face (also referred to as mating surface) of relay valve 21.As shown in Fig. 2 and 3, in the present embodiment, in frame Portion 44 is used for for solenoid valve 30 to be fixed on to through hole 48,1 that the screw 31 of relay valve 21 penetrates through by gasket there are two being formed 40 through holes 49 positioned relative to solenoid valve 30 or relay valve 21 are formed in the position separated from through hole 48.
Gasket 40 has connection frame portion 44 and flow path forming portion 42, the plate portion 45 that can be such as plate.Plate portion 45 with Flow path forming portion 42 and frame portion 44 are integrally formed.In the present embodiment, plate portion 45 be set as with flow path forming portion 42 and The cooperation of frame portion 44 vibrates attenuating space 43 to mark off.Therefore, flow path forming portion 42 utilizes plate portion separating with frame portion 44 45 support and position.
Vibrating attenuating space 43 includes than plate portion 45 close to the solenoid valve side space 43a of the position of solenoid valve 30 and than plate portion 45 close to the position of relay valve 21 relay valve side space 43b.Plate portion 45 is set as dividing vibration attenuating space 43 for solenoid valve side Space 43a and relay valve side space 43b.In other words, plate portion 45 on the thickness direction of gasket 40 from the central portion of frame portion 44 The mode to extend internally shapes.Plate portion 45 is connected to different from the central portion of flow path forming portion 42 on the thickness direction of gasket 40 Position.Flow path forming portion 42 can be in the 1st side of gasket 40 and the 2nd side (such as the upper side and lower side of Fig. 4) with different height Degree protrudes.In the present embodiment, compared to frame portion 44, the projecting height of flow path forming portion 42 to solenoid valve side is big.
The thick wall portion that plate portion 45 has hemispherical protrusion 46 thicker than other positions in the plate portion 45 as thickness.Example Such as, 6 protrusions 46 are respectively provided in the two sides opposite with solenoid valve 30 and relay valve 21 in plate portion 45.In each face in plate portion 45, Protrusion 46 is configured between flow path forming portion 42 and frame portion 44.The height away from plate portion 45 of protrusion 46 is with frame portion 44 away from plate The height in portion 45 is identical.Therefore, can using plate portion 45 46 holding plate portion 45 of protrusion at a distance from the end face of solenoid valve 30 with And plate portion 45 is at a distance from the end face of relay valve 21, it can be ensured that vibration attenuating space 43.
There is the interconnecting part 47 of the inner and outer of connection frame portion 44 in frame portion 44.Interconnecting part 47 will vibrate attenuating space 43 It is connect with the atmosphere of the outside as gasket 40.Interconnecting part 47 is set to the two sides of gasket 40.Due to flow path forming portion 42 Deterioration, the surface roughness deterioration of hermetic unit or attachment of foreign matter etc., compressed air declines from flow path forming portion 42 to vibration In the case where subtracting the leakage of space 43, the compressed air of the leakage can be passed through interconnecting part 47 to the outside of frame portion 44 by interconnecting part 47 Discharge.
Then, referring to Fig.1~Fig. 4 illustrates the effect of gasket 40 as constituted above.
It works in valve gear 20, generates vibration from solenoid valve 30 along with the reciprocating movement of the valve body 33 of solenoid valve 30 When, inhibit the propagation of vibration using gasket 40.Specifically, the end face of solenoid valve 30 edge and relay valve 21 end face In the state that edge clips and keep the frame portion 44 of gasket 40, solenoid valve 30 is connect with relay valve 21.Solenoid valve 30 and relay valve 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 Space 43b.Therefore, passed through by the vibration that solenoid valve 30 generates in solenoid valve side space 43a, plate portion 45, relay valve side space 43b It is middle propagation and be attenuated and to relay valve 21 propagate.
In addition, the two sides in this plate portion 45 is equipped with protrusion 46.In solenoid valve 30 and relay valve 21 when sandwiching power and becoming larger, pad The protrusion 46 of piece 40 is compressed.Therefore, it is able to suppress plate portion 45 and solenoid valve 30 or relay valve 21 is invested with face paste, be able to maintain that Solenoid valve side space 43a and relay valve side space 43b.And then it is able to maintain that and utilizes solenoid valve side space 43a and relay valve The decaying of side space 43b.
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.
