The system that vibration is transmitted from the compressor 10 as exciting source to accumulator 20 is fixed on the piping 21,22 in container 20A, to the greatest extent may be used
The vibration of piping 21,22 can be made to be not passed to the outside of container 20A, container 20A.
In order to reliably make the vibration of piping 21,22 decay, vibration transmission system is fixed on the piping in container 20A
21,22, preferably the distance big piping 21,22 of relative displacement caused by the Relative Vibration by bracket 30 to piping 21,22
Position is constrained each other.
In order to make the vibration of piping 21,22 decay, it is also contemplated that be covered in the piping extended in container 20A as far as possible
21, the mode of 22 peripheral part is arranged the elastomers such as rubber, but so the weight of accumulator 20 increases, and may not with fill
The vibration decaying divided is related.
It in the present embodiment, can be by the bracket 30 that is detached with container 20A, to the portion of piping 21,22 in container 20A
Position is constrained each other, thus seeks efficiently to vibrate decaying.
The bracket 30 of present embodiment can be substituted using bracket shown in Fig. 3 (b), Fig. 3 (c).
Bracket 35 shown in Fig. 3 (b) has：Maintaining part 351,352 is in C fonts when from upper and lower directions；And connection
Portion 33, to maintaining part 351,352 into joining line.
Bracket 35 is formed bending two ends at the C word shapes of point symmetry by being punched metallic sheet material.In linking part 33
The parts of bending two ends be equivalent to maintaining part 351,352.
Maintaining part 351,352 is in C fonts, and gap Sp is vacated in the part adjacent with linking part 33.Therefore, it is being kept
Piping 21,22 vibrate when, maintaining part 351,352 can be opened and closed.
The bracket 35 of Fig. 3 (b) is easy to make, and since the opening and closing of maintaining part 351,352 deforms, vibration decaying
Effect it is high.
Bracket 36 shown in Fig. 3 (c) has：Linking part 361, configures along horizontal direction；And maintaining part 31,32, lead to

[second embodiment]
With reference to Fig. 6~Fig. 9, second embodiment of the present invention is illustrated.
In this second embodiment, for using bracket that the piping 21,22 to accumulator 40 constrained each other can be into
The structure that one step improves the attenuating of vibration illustrates.
As shown in fig. 6, length direction of the accumulator 40 of second embodiment in straight portion 21A, 22A of piping 21,22
Two at different location have bracket 41,42.
Bracket 41,42 can be configured to identical as bracket 30 (Fig. 3 (a)) illustrated in first embodiment.
Bracket 41,42 can also be configured to Fig. 3 (b) and (c), bracket 37~39 shown in Fig. 5 (a)~(c) it is identical.
In the present embodiment, bracket 41,42 is configured at regulation height in order to more fully obtain vibration-damping effect
Degree.
Here, when will be in the benchmark lower end 21L's of the top from 21,22 respective lower end 21L, 22L of piping
Height of the position P1 (terminus position) until being piped 21,22 respective upper end 21U, 22U position P2 (apical position) arranged side by side
When degree is set as " 1 ", bracket 41 is located at about 0.5 height (the first height H1), and bracket 42 is located at about 0.8 height (the second height H2)
Place.
Bracket 41 constrains the first position 211 of piping 21 and the first position 221 of piping 22.First position 211
It is at identical height with first position 221.
Bracket 42 constrains the second position 212 of piping 21 and the second position 222 of piping 22.Second position 212
It is at identical height with second position 222.
In order to play the restraining force to piping 21,22, can be sized to the bracket 41,42 of upper and lower directions is respective
The suitable size of 1mm or more.
More specifically, as with shown in single dotted broken line, terminus position P1 is the lower end with piping 21,22 in Fig. 6
The upper end of the bending section 21B of the piping 21 (benchmark piping) of benchmark lower end 21L in top in 21L, 22L.If from there
Start computed altitude, is then piped 21,22 extending in parallel in the entire height throughout " 1 " and is therefore well suited for shaking for aftermentioned beam
Movable model (Fig. 8, Fig. 9).
When height until from terminus position P1 to apical position P2 is set as " 1 ", bracket 41 is configured at throughout comprising 0.5
In range near height H1 and height H1.
Similarly, when the height until from terminus position P1 to apical position P2 being set as " 1 ", bracket 42, which is configured at, to be spread

More specifically, for the size using bracket 41,42, above and below the preferably straight portion 21A extensions of bracket 41
The central part of the bracket 41 of direction D1 is at about 0.5 height H1.In bracket 42 about 42 preferred upper and lower directions D1 of bracket
Center portion is at about 0.8 height H2.
Hereinafter, the reasons why to bracket 41,42 is configured at specified altitude, illustrates.
Fig. 7 (a)~(c) indicates the piping for being connected to the accumulator of existing (bracket of no piping) of rotary compressor
91,92 vibration analysis result.
Fig. 7 (a) indicates that a vibration mode ingredient, Fig. 7 (b) indicate that secondary vibration pattern elements, Fig. 7 (c) indicate three times
Vibration mode ingredient.
Although there is also four times or more vibration mode ingredients, piping 91,92 all vibrations in, frequency it is low and
Sound pressure levels are high, therefore emphasis is wanted to make and noise is relevant once decays to vibration three times.
As described above, in order to make vibration-damping effect improve, preferably by bracket 30 to the Relative Vibration because of piping 21,22
And the position for the piping 21,22 that the distance of relative displacement becomes larger is constrained each other.
In this regard, being illustrated with reference to Fig. 8 (a)~(c).
Piping 21,22 is respectively provided with fixing end 201 and the free end 202 for the bottom 23 (Fig. 6) for being riveted on container 20A.
Fig. 8 (a)~(c) indicates each vibration mode ingredient primary, secondary, three times respectively.
Under a vibration mode shown in Fig. 8 (a), with being gradually increased close to 202 amplitude of free end, with amplitude
Increase, the relative displacement at the position of the identical position for being piped 21 of the height apart from fixing end 201 and piping 22 increases.
Under the secondary vibration pattern shown in Fig. 8 (b), there are the section B of amplitude maximum abdomen A and amplitude minimum.Here, away from
The maximum position of relative displacement at the position at the identical position for being piped 21 of height and piping 22 from fixing end 201 is not abdomen A
Position, but save B position.In the position of abdomen A, the opposite position at the position of the identical position for being piped 21 of height and piping 22
It moves minimum.
Arrow shown in Fig. 8 (b) indicates for the position by the restrained piping 21,22 of bracket (double dot dash line), with
On the basis of the position of the section B of piping 21, it is piped the direction of the position relative displacement of 22 section B.
As in Fig. 8 (b) with shown in double dot dash line, at the position corresponding to section B, by bracket to piping 21,22 each other
When being constrained, about quadratic modes, the vibration-damping effect highest realized by piping 21,22 and the deformation of bracket, friction.
Shown in Fig. 8 (c) three times under vibration mode, there are two section B1, B2 and two abdomens A1, A2, but with it is secondary
Vibration mode similarly, the relative displacement at the position of the identical piping of height apart from fixing end 201 21 and the position of piping 22
Maximum position is the position for saving B1, B2.
Arrow shown in Fig. 8 (c) indicates for the position by the restrained piping 21,22 of bracket (double dot dash line), with
On the basis of the position of section B1, B2 of piping 21, it is piped the direction of the position relative displacement of 22 section B1, B2.
As in Fig. 8 (c) with shown in double dot dash line, when corresponding to first segment B1 position and corresponding to the position of the second section B2
It sets at two, when constrained each other piping 21,22 by bracket, about tertiary mode, by piping 21,22 and the change of bracket
The vibration-damping effect highest that shape, friction are realized.
Even if the phase for the vibration for being piped 21,22 it is identical, have phase difference or in the case that only a side resonates,
Also following relationship is set up：Since the relative displacement of the piping 21,22 at the position of section is maximum, bracket maximally tilts, and
Relative displacement is minimum at the position of abdomen, therefore bracket does not tilt.Therefore, shown in such as Fig. 8 (b) and (c), can with piping 21,
The phase of 22 vibration independently determines the position of the highest bracket of vibration-damping effect.
Secondary shake is calculated based on fundamental formular when determining the position of restrained piping 21,22 based on the above content
The position of section B1, B2 of the position of the section B of dynamic model formula and three times vibration mode.
Fig. 9 (a)~(c) indicates each vibration mode ingredient primary, secondary, three times respectively.
In Fig. 9 (b), such as pass through the example of the calculated numerical value of vibration of beam formula with fixing end and free end
Shown, the section B of secondary vibration pattern is in when the length until from fixing end 201 to free end 202 is set as " 1 "
The position of " 0.774 ".
Similarly, in Fig. 9 (c), such as pass through the calculated number of vibration of beam formula with fixing end and free end
Shown in the example of value, when the length until from fixing end 201 to free end 202 is set as " 1 ", the section B1 of vibration mode three times
Position in " 0.500 ", three times the section B2 of vibration mode be in the position of " 0.868 ".
As shown in Fig. 9 (a), it is also contemplated that under a vibration mode, in free end 202 that is position in " 1 "
Locate amplitude maximum, the relative displacement of piping 21,22 is also maximum therewith.
According to the above, in order to make once well fully to decay to vibration mode balance three times, in this embodiment party
In formula, as the position constrained each other piping 21,22 at selected 0.5 height H1 as shown in FIG. 6 and 0.8 height H2 two
It sets.Bracket 41,42 can be configured at height H1, H2 one by one on the basis of these height H1, H2.
By bracket 41,42, slightly offset from the position of 0.8 height H2, such as a pattern the big piping 21,22 of amplitude
Upper end 21U, 22U near, the position of the section B2 of tertiary mode also can be by the shadow for the restraining force realized by bracket 41,42
It rings, therefore the vibration of piping 21,22 can efficiently be made to decay.
According to second embodiment, in the position of the maximum section of relative shift comprising mutually level piping 21,22
Height at, which is constrained by bracket 41,42 each other, therefore can more fully obtain shaking of illustrating in the first embodiment
Dynamic attenuating.
The accumulator 40 of second embodiment can also have in container 20A other than bracket 41,42 to piping
21,22 other brackets constrained each other.
It in addition to the above, can be to knot cited in the above embodiment without departing from the purport of the present invention
Structure carries out choice selection, can also suitably change as other structures.
For example, as shown in Figure 10, can also lead in the range comprising two side of 0.5 height H1 and 0.8 height H2
A bracket 45 is crossed to constrain piping 21,22.In this case also similarly to the second embodiment, vibration can be made more abundant
Decay on ground.
The basic conception of the present invention is, as illustrated in first embodiment column, passes through the support detached with container 20A
Frame constrains more than two pipings in container 20A each other, in this regard, is not carried out to the position of bracket, quantity
It limits.
It therefore, as shown in figure 11, also can be by detached at three detached in above-below direction, with container 20A three
Bracket 46~48 constrains piping 21,22 in container 20A.
Such as above-mentioned each embodiment, the present invention is suitble to two cylinders for having corresponding to dual rotation type compression mechanism 11
113, the accumulator 20,40 of 123 two pipings 21,22, but it is not limited to this composition.If refrigerant from accumulator 20,
