In from Fig. 1 to Fig. 4, enclose oil 101 and refrigerant gas (figure does not show) in the seal container 1 that forms iron plate being carried out pull and stretch processing, and the compression unit 103 that contains electrodynamic element 2 and drive by it.In addition, in order to install seal container 1 is fixed on the parts (figure does not show) that pedestal (figure do not show) waits, formation planar surface portion 1A on seal container 1.
Form cylinder 5 on the cylinder unit 4 that constitutes compression unit 103, piston 6 is inlaid in the cylinder 5 in the mode that can back and forth move freely.
The end of laminal plate body 7 closed cylinder when forming the inlet hole 8 and the hole 9 that spues.
With having improved the suction silencing apparatus 110 that PBT (poly terephthalic acid succinate) resin of heat resistance, oil resistance, refrigeration is made by sneaking into glass fibre about 15%, possess its one side being substantially of seal container 1 inner opening cuboidal opening portion 111, form the silence space portion 112 of expansion silencing apparatus and be communicated with in the silence space portion 112 and the connecting tube portion 113 of inlet hole 8.
On connecting tube portion's opening end 114 of 113, be provided with the guiding path 115 of the groove shape of the sectional area that in 114 inside and outside connections of opening end, also has regulation and length, in addition, also be formed with the seat 116 that becomes half moon ring-type substantially.And then, in connecting tube portion 113, also be formed with to the outstanding flange part 118 that is U word shape substantially of the outer circumferential side except the face of opening end 114 sides.In addition, the bottom of silence space portion 112 be positioned at flange part 118 above the position on be formed with oil drainage hole (oil dripping hole) 119.
What seat 116 modes along inwall with ring-type of being formed with on container 125 formed is half moon resonant chamber 128 substantially, thereby and be formed be arranged on flange part 118 corresponding positions on the slot part 129 that is U word shape substantially of small movable fit flange part 118.
Cooperate with cylinder cap 123 by sucking silencing apparatus 110, flange part 118 is chimeric with slot part 129, thereby forms sealed department 130.In addition, by plate body 7, connecting tube portion's 113 outer circumferential faces, ring-type the inner peripheral surface of seat 116 and the internal face of resonant chamber 128 constitute space 132, this space 132 forms sympathetic response silencing apparatuss 140 with guiding path 115.
Then, by cylinder cap 123 is bolted on the cylinder unit 4 between utilizing medially with plate body 7, sucking silencing apparatus 110 has spring 142 ground to be plugged cramping by cylinder cap 123, be fixed on the plate body 7 with regard to centre Jie.
In addition, the planar surface portion 1A of seal container 1 has the resonant frequency of about 2.5kHz, and the resonant frequency of opening portion 111 is set at about 1.6kHz, in order to avoid consistent with the resonant frequency of planar surface portion 1A.
On the other hand, sympathetic response silencing apparatus 140 is tuned as and opening portion 111 essentially identical resonant frequencies.
For the compressor that constitutes by above mode, below its action of explanation.
By coming drive compression unit 103 to electrodynamic element 2 supply capabilities, by piston 6 to-and-fro motion in cylinder, turn back to seal container 1 interior refrigerant gas by refrigeration cycle (scheming not show) and sucked to silence space portion 112, again from the suction in cylinder 5 of connecting tube portion's 113 process inlet holes, 8 quilts from the opening portion 111 that sucks silencing apparatus 110.Then, the compressed refrigerant gas chamber 124 that spues that spued to from the hole 9 that spues by the to-and-fro motion of piston 6 is sent to refrigeration cycle (figure does not show) once more.
At this moment, through inlet hole 8 by the refrigerant gas of suctions to cylinder 5 in by piston 6 to-and-fro motion and being sucked by spells in cylinder 5, thereby can supervene very strong pressure pulsation.This pressure pulsation is weakened widely by means of the effect of effect that is located at the expansion silencing apparatus in the silence space portion 112 that sucks on the silencing apparatus 110 and sympathetic response silencing apparatus 140.
In addition, remain in the pressure pulsation in the sympathetic response silencing apparatus 140, because sympathetic response silencing apparatus 140 is suppressed with seal container 1 inner sealed 130 isolation thereby to seal container 1 internal leakage, thereby prevented the propagation of the vibration of the refrigerant gas in seal container 1.Consequently, the effect of the effect of above-mentioned expansion silencing apparatus and sympathetic response silencing apparatus 140 works effectively, can noise-decreasing.
Though sealed department 130 is formed by flange part 118 and the chimeric of slot part 129, but because the total of the upper and lower surface of flange part 118 and outer circumferential face distance is the effective length of sealed width, so,, thereby can obtain good sealing property because sealed width is done one's utmost effect.
On the other hand, when will sucking silencing apparatus 110 and cylinder cap 123 cooperate, because of flange part 118 becomes U word shape substantially, thus the radian of the shoulder of flange part 118 be easy to cooperate with slot part 129, thereby obtained good operability.
In addition, the refrigerant gas that sucks from opening portion 111 contains vaporific oil (figure does not show), and this oil is separated from refrigerant gas in silence space portion 112.These separated oil stockpile in the bottom that sucks silencing apparatus 110, drip to sealed department 130 from oil drainage hole 119.Its result, because of oil is soaked in the small gap that sealed department 130 forms its sealing, so sealing has had the raising of leaping property, the pressure pulsation that remains in the sympathetic response silencing apparatus 140 can not leaked substantially again, the effect of the effect of above-mentioned expansion silencing apparatus and sympathetic response silencing apparatus 140 plays a role more effectively, can noise-decreasing.
Because resonant chamber 128 is to be formed to encircle seat 116 modes along inwall that are half moon ring-type substantially that into circular arc to chamber 124 sides that spue, so spatial volume of not dwindling the chamber 124 that spues, resonant chamber 128 can obtain maximum volume in limited space, therefore, can improve the effect of sympathetic response silencing apparatus 140, obtain bigger erasure effect.Simultaneously, the seat 116 of the ring-type that forms in mode along the inwall of resonant chamber 128 limited effectively with connecting tube portion's axle of 113 be the moving of sense of rotation at center.Thus, be pressed when being fixed on the plate body 7 when sucking silencing apparatus 110, stability improves, and sucks silencing apparatus 110 and is securely fixed on the position of regulation.Consequently, can prevent becoming flexible and the vebrato of generation between excuse 7 and the suction silencing apparatus 110.
In this example 1, sympathetic response silencing apparatus 140 is tuned as resonant frequency and opening portion 111 essentially identical about 1.6kHz, so the resonance sound of opening portion 111 is weakened significantly.Its result has and reduces because of opening portion 111 becomes the effect of encouraging vibration source, the sympathetic response portion of seal container being encouraged the noise that causes of shaking significantly.
In addition, be formed on the seal container 1 planar surface portion 1A rigidity a little less than, consequently, when with planar surface portion 1A intrinsic vibration number encourage when shaking, this part is easy to resonance, is easy to take place very big noise.But in this example 1, as previously mentioned, by make the resonant frequency that becomes the opening portion 111 of encouraging vibration source easily and planar surface portion 1A intrinsic vibration number inconsistent, and set respectively, thereby come from encouraging the power of shaking and can not making amplitude amplification of opening portion 111, therefore can suppress the generation of noise at the planar surface portion 1A place of the easiest sympathetic response of seal container 1.
Moreover, owing to suck silencing apparatus 110 on its structure, have space length miscellaneous in inside, therefore the wavelength according to the noise that passes through is exaggerated greatlyyer sometimes.In this case, consistent by the sound that makes this frequency with the resonance frequency of sympathetic response silencing apparatus 140, the noise that is exaggerated is weakened, it also is very effective that such method reduces for noise.
The effect of this example is for being used in the refrigerant gas on refrigeration and cold storage, the airconditions such as refrigerator or showcase and can obtaining equally with respect to the oil that it possesses intermiscibility.
