In Fig. 2A and Fig. 2 B, the reed valve device 10 of present embodiment is illustrated.Fig. 2A is top view, and Fig. 2 B are signal
Represent to property the schematic diagram of a part for the section along the b-b lines shown in Fig. 2A.
As illustrated, reed valve device 10 includes valve seat 20, reed 30 and limiter 40.Valve seat 20 has：Fluid bore
21, it is connected on above-mentioned pipe arrangement 8；Hole opening portion 22, it is formed on the port of export of fluid bore 21；And dropping place face 23,
It is formed on the edge part of hole opening portion 22.Above-mentioned mixed flow as fluid is in 30 valve opening of reed, in fluid bore 21
Flow up, and discharged from hole opening portion 22.Although the plan view shape of hole opening portion 22 is as shown in Figure 2 A ellipse, should
Shape is arbitrary.
Reed 30 is made up of the thin plate of metal system or plastic elastically deformable.Reed 30 has：Reed cardinal extremity
Portion 31, it is fixed on the dropping place face 23 of valve seat 20；And reed extension 32, it extends to top from reed base end part 31
Side (Fig. 2 B right side), and device to hole opening portion 22 is switched.By reed base end part 31 and the boundary position of reed extension 32
Represented with X in figure.Pressure in hole opening portion 22 (is referred to as " hole internal pressure ") Pa and (is referred to as with the pressure outside hole opening portion 22
" during the equal normal conditions of hole external pressure ") Pb, reed 30 has basic configuration as depicted (shape when not deformed).
The ascending amount that limiter 40 is used to limit reed 30 (especially reed extension 32) in 30 valve opening of reed is (from falling
Plane 23 is to the top of figure or the amount of movement of valve opening position).Although limiter 40 is made up of metal system or plastic plate,
But thickness ratio reed 30 is thick, and elastic deformation will not substantially occur.Limiter 40 includes：Limiter base end part 41, it is folded
It is fixed on reed base end part 31；And limiter extension 42, it extends to tip side from limiter base end part 41, and
Extend along oblique direction.The boundary position of limiter base end part 41 and limiter extension 42 is also represented with X.
Reed 30 is tightened by common bolt 50 and fixed with limiter 40 jointly in cantilever manner.That is, pad has been inserted through in advance
The bolt 50 of circle 51 is inserted through the bolt-inserting hole 49 being arranged on limiter base end part 41 and is arranged on reed successively
Bolt-inserting hole 39 on base end part 31, and be screwed into the in the internal thread hole 29 being arranged on dropping place face 23.Certainly, reed
30 with the fixing means of limiter 40 be it is arbitrary or, both are fixed respectively, it is also possible that with beyond bolt
Means are fixed.
Limiter 40 includes bending section 43, and the bending section 43 is arranged on limiter base end part 41 and limiter extension 42
Boundary position X, and be bent so that limiter extension 42 relative to limiter base end part 41 ramp up direction (Fig. 2 B's
Top) tilt.In fig. 2, the sweep 43L of bending section 43 is illustrated.Sweep 43L is leaning on base end side than hole opening portion 22
Boundary position X on, be linear.Limiter extension 42 is ramped up at bending section 43 relative to limiter base end part 41
Direction has only bent angle [alpha] 1 so that limiter extension 42 is relative to the face direction in dropping place face 23 into predetermined upward angle [alpha]
1。
The feature of present embodiment is especially embodied on following point：It is curved under the basic configuration shown in Fig. 2A and Fig. 2 B
It is bent so that the reed extension 32 of reed 30 is with from base end side (Fig. 2A and Fig. 2 B left side) to tip side (Fig. 2A and Fig. 2 B
Right side) and away from dropping place face 23.
Fig. 3 individually represents the reed 30 in basic configuration.As shown in Fig. 2A, Fig. 2 B and Fig. 3, reed extension 32
With bending (face) shape, especially in the length direction from the lateral tip side of cardinal extremity, particularly in total length, there is constant curvature
Radius R.Unlike this, reed base end part 31 has the flat shape for the flat shape for imitating dropping place face 23.Reed base end part 31
Also there is above-mentioned bolt-inserting hole 39.
As shown in Figure 2 A and 2 B, in the present embodiment, reed extension 32 is bent to the top of reed extension 32
End 33 is abutted with limiter extension 42 or hand-to-hand degree.However, the degree of crook is arbitrary.In this way, as spring
The result that piece extension 32 is bent, when reed extension 32 as shown is normal condition, open hole opening portion 22.
Next, the action effect of narration present embodiment.
When in hole, internal pressure Pa is below the predetermined valve closing pressure of the 1st predetermined value lower than hole external pressure Pb, as shown in figure 4, reed
Extension 32 is close on dropping place face 23, and lipostomous opening portion 22, turns into closed valve state.Thus, the via openings of through-flow body
The circulation in portion 22 is prevented from.Now, reed extension 32 is elastically deformed into flat shape from basic curved shape.
Here, above-mentioned 1st predetermined value is to make the curved shape elastic deformation of reed extension 32 must into flat shape
The minimum value needed.The thinner thickness of reed 30 and reed extension 32 (such as 0.2mm or so), can easily elastic deformation,
The ascending amount H1 also minimum (about 1.5mm or so) of the top ends 33 of reed extension 32 under normal condition.Therefore, in practicality
On, it can ignore to the pressure (above-mentioned 1st predetermined value) required for the elastic deformation of such flat shape, reed extension 32
, will lipostomous opening portion 22 when in hole, internal pressure Pa is lower than hole external pressure Pb.
On the other hand, when hole internal pressure Pa is higher than above-mentioned valve closing pressure, the open bore opening portion 22 of reed extension 32, turn into out
Valve state, and allow the circulation by hole opening portion 22 of fluid.Moreover, it is more predetermined than hole external pressure Pb the high 2nd in hole internal pressure Pa
During the predetermined standard-sized sheet pressure above of value, reed extension 32 is close to (stickup) on the lower surface 47 of limiter extension 42, makes
The standard-sized sheet of hole opening portion 22, turns into full-gear.Now, reed extension 32 relative to reed base end part 31 in the position of bending section 43
Put and bend obliquely upward, reed 30 is elastically deformed so that the basic curved shape of reed extension 32 is changed to imitate limit
The flat shape of the shape of the lower surface 47 of device extension 42 processed.Thus, the ascending amount of reed 30 or reed extension 32 is limited
System.
Here, when reed extension 32 is changed into closed valve state from full-gear, reed extension 32 is from flat shape
It is changed into curved shape for the time being, is changed into flat shape afterwards.By beam mode as addition, so as to by reed 30
Transformation when being changed into closed valve state from full-gear is carried out than relatively slowly, and can postpone the valve closing timing of reed 30.
The point is compared to illustrate with the 1st comparative example.In Fig. 5 A and Fig. 5 B, the reed of the 1st comparative example is illustrated
The basic status of valve gear.Fig. 5 A are top view, and Fig. 5 B are schematically show section along the b-b lines shown in Fig. 5 A one
Partial schematic diagram.For the sake of convenient, identical reference is marked for key element corresponding with the key element in present embodiment.The
1 comparative example is mainly different from present embodiment on following point：The basic configuration of reed extension 32 is not curved shape, and
It is the flat shape extended straight from reed base end part 31.
In the 1st comparative example, the reed being close under full-gear on the lower surface 47 of limiter extension 42 extends
Portion 32 (for flat shape) can decline (elasticity recover) in valve closing, and be connected to dropping place face 23 and lipostomous opening portion 22.This
When, because the basic configuration of reed extension 32 is flat shape, its planar shaped is being remain by reed extension 32
In the state of shape centered on the position of bending section 43 and hinge shape rotate, merely eliminate bending, so as to return to valve closing
State.Between full-gear to closed valve state, the shape of reed extension 32 hardly changes.Therefore, can be drastically extensive
Closed valve state is arrived again, it is difficult to postpones the valve closing timing of reed 30.
Unlike this, in the present embodiment, because can extend reed between full-gear to closed valve state
The shape in portion 32 changes, so correspondingly, can slowly carry out the transformation to closed valve state, and can postpone reed 30
Valve closing timing.In this case, the action during valve closing of reed 30 is made to become compared with the 1st comparative example
Change, and delay the valve closing timing of reed 30.The fact that the valve closing constant time lag of reed 30, also passes through test etc. by the present inventor
Confirmed.
In addition, in this case, when being transformed into closed valve state from full-gear, reed extension 32 is from base
Side is risen gradually to the dropping place of dropping place face 23, and gradually curved shape is changed to flat shape from base end side.In addition, from base
When this curved shape is changed into final flat shape, although very little, hole internal pressure Pa and hole external pressure Pb pressure are needed
Difference is only above-mentioned 1st predetermined value.These are recognized as the reasons why valve closing constant time lag of reed 30.
In addition, in this case, there is also as follows the advantages of：Can it is more reliable than the 1st comparative example simultaneously
And stably carry out the sealing of the hole opening portion 22 in closed valve state.
Fig. 6 represents the dropping place situation of the reed extension 32 in present embodiment.Because the length side of reed extension 32
Upward radius of curvature R is constant, so when reed extension 32 is changed into flat shape from curved shape, by equally spaced every
Deflection S1, S2, the S3 for the time per unit at each lengthwise location Q1, Q2, Q3 opened are identical.Therefore, in closed valve state
Under, uniform sealing pressure P can be applied to dropping place face 23, and can reliably and stably carry out the sealing of hole opening portion 22.
If on the other hand, in the case of the 1st comparative example shown in Fig. 7, reed extension 32 only carries out above-mentioned hinge shape
Bending as a result, near the base end part of reed extension 32 sealing pressure P have with than its by tip side sealing press P compared with
Small tendency.Therefore, as a result, sealing pressure P has deviation, in the 1st comparative example, sealing and this implementation of hole opening portion 22
Mode is compared to poor.
In addition, the reed extension 32 of present embodiment is gradually converted into flat when being changed into closed valve state from base end side
Face shape, and be close to dropping place face 23.According to such deformation method, on present embodiment, even if reed extension 32
The radius of curvature R of length direction is not constant, can also obtain good dropping place state, and can stably be sealed.
Incidentally, in the application examples of the reed valve device 10 of present embodiment, determined by the valve closing for postponing reed 30
When, the advantages of so as to obtain as follows.
That is, in the case of the reed valve device of the 1st comparative example of application, in the engine 1 shown in Fig. 1, it is true to there is driving
The variation of driving moment during empty pump 4 is larger, can from drive system of pump produce abnormal sound the problem of, such as from connector 3 produce machine
The problem of tap-tap of tool.As the 1st comparative example, if reed 30 rapidly valve closing, Pa ＜ Pb, and carried out in reed 30
During valve closing acts, countercurrently reduced to the amount of the air (being represented in the figure 7 with arrow J1) in hole opening portion 22.Cause
This, in fluid bore 21 or even the inside of vavuum pump 4, oil mass ratio and air capacity ratio are compared to significantly increasing, because oil is non-depressed
Contracting fluid, so the oil in compression pump changes with the driving moment during fluid-mixing of air and becomes big, produce abnormal sound.
However, in the present embodiment, because the valve closing constant time lag of reed 30, Pa ＜ Pb, and in reed 30
During carrying out valve closing action, adverse current can be increased to the air (being represented in figure 6 with arrow J1) in hole opening portion 22
Amount.Therefore, it is possible to increase the air capacity ratio in vavuum pump 4.Because air is compressible fluid, can suppress to compress
The driving moment during fluid-mixing of oil and air in pump changes, and suppresses the generation of abnormal sound.
In addition, as shown in figure 8, another the 2nd comparative example also be present, the 2nd comparative example is included in the hole for overlooking lower bending
Opening portion 22, reed (not shown) and limiter 40.Sectional view is identical with Fig. 4 B.Because the 2nd comparative example is also compared with the 1st
Example has identical action effect, so present embodiment is better than the 2nd comparative example.
The plan view shape of present embodiment can also be changed into curved shape as shown in Figure 8.
Although next, similar with present embodiment, the other comparative examples different with present embodiment are carried out
Compare, the advantages of illustrating present embodiment.
In fig.9, the reed 30 of the 3rd comparative example in basic configuration is individually illustrated.Reed extension 32 has curved
Bent (face) shape, is formed with present embodiment by the same manner as.However, reed base end part 31 is different from present embodiment, have with
Continuously bending (face) shape, and be formed on bolt-inserting hole 39 of reed extension 32.That is, the reed of the 3rd comparative example
30 entirety have curved shape, and the overall radius of curvature R of its length direction is set as constant.
In this way, when mounted, the elastic deformation of reed base end part 31 is forcibly set to be planar shaped by the fastening force of bolt 50
Shape is installed.Accordingly, there exist following shortcoming：In the mounted state, the power for loosening bolt 50 acts on all the time, and bolt 50 is easily loose
It is dynamic.
But because the basic configuration of the reed base end part 31 of the reed 30 of present embodiment is flat shape, no
The power for loosening bolt 50 can be acted on, and the shortcomings that such can be eliminated.
Certainly, in the 3rd comparative example, the also reed extension 32 comprising curved shape, and having obtained by the way that reed is prolonged
Extending portion 32 is set to curved shape and the above-mentioned action effect of caused present embodiment.Therefore, the 3rd comparative example is comprised in this hair
In bright embodiment.
In Fig. 10, the reed valve device 10 of the 4th comparative example is illustrated, especially illustrates the reed in basic configuration
30.As illustrated, reed extension 32 is not curved shape, but the basic configuration with flat shape.But reed extends
Portion 32 in the position of bending section 43 or boundary position X, by with the small angle [alpha] 2 of the angle [alpha] 1 than limiter 40 relative to reed base
End 31 ramps up direction bending.That is, reed 30 is bent in advance in the position.Thus, reed extension 32 is as shown in the figure
On the basis of state when, open hole opening portion 22.
In this case, as shown in figure 11, when the elastic deformation of reed 30 is into closed valve state, in the position of bending section 43
Neighbouring reed extension 32 has the tendency of remote dropping place face 23 (tilting) (diagram has exaggeration), it is impossible to ensures to fill near the position
The sealing pressure divided, can exist and seal unstable risk.This is roughly the same with the 1st comparative example shown in Fig. 7.
But according to present embodiment, as described above, can also obtain sufficiently sealing pressure, and energy even in the position
It is enough stably to be sealed.
More than, although describing embodiments of the present invention in detail, the present invention also likely to be present other implementations
Mode.For example, it is also possible to be, the radius of curvature R of reed extension 32 is not in the longitudinal direction to be constant, it is also possible that making it
Changed according to the position of length direction.
Embodiments of the present invention are not limited only to above-mentioned embodiment, by the think of of the invention of claims defined
Want that all variations for being included and application examples, equivalent are also contained in the present invention.Therefore, the present invention should not be defined ground
Explain, other any technologies of the ownership in the range of the thought of the present invention can also be applied to.
