Specific embodiment
In conjunction with referring to figs. 1 to 5, according to an embodiment of the invention, a kind of cylinder holder assembly, is located on cylinder block 1,
Including chamber and separator, the separator is located in the chamber, and the chamber is divided into the different anechoic chamber of volume；Institute
It states separator and is equipped with the through-hole that the adjacent anechoic chamber is connected.
By casting exhaust noise silencing chamber 2 chamber in increase separator, exhaust noise silencing chamber 2 volume size substantially not
In the case where change, exhaust noise silencing chamber 2 is divided into multiple anechoic chambers, different and adjacent that of the volume size of multiple anechoic chambers
This is connected, and exhaust noise silencing chamber 2 is enabled to eliminate the noise of multiple frequency ranges, and noise reduction frequency band is widened, and reduces exhaust noise.
The inlet channel and outlet passageway of chamber are connected to from different anechoic chambers, and phase is connected by the through-hole on separator
The anechoic chamber Lin Liangge extends time of the gas in exhaust noise silencing chamber 2, causes the gas pulsation frequency of discharge to reduce, also reaches
To the purpose for reducing exhaust noise.
Separator includes the different sleeve member of multiple internal diameters, multiple sleeve members sheathed setting with a gap；The set
The wall of cylinder part is equipped with the through-hole.By multiple sleeve members being arranged, chamber be separated along the radial direction of sleeve member,
The different anechoic chamber of multiple volume sizes can be formed, the noise of multiple frequency ranges is eliminated.In addition gas is via logical on sleeve member wall
Hole flowing, it is opposite to extend the time in exhaust noise silencing chamber 2, cause the gas pulsation frequency of discharge to reduce, also reaches reduction
The purpose of exhaust noise.
Preferably to extend residence time of the gas in exhaust noise silencing chamber 2, two adjacent sleeve members, each sleeve member
On set a through-hole, a shaft section is set on a sleeve member；One through-hole is located at shaft section side, and where the through-hole
Diameter is located at the other side of shaft section perpendicular to shaft section, another through-hole；And/or a through-hole is located at the upper of place sleeve member
Half portion, another through-hole are located at the lower half of place sleeve member.It is opposite to extend the time in exhaust noise silencing chamber 2, cause to be discharged
Gas pulsation frequency reduce, also achieve the purpose that reduce exhaust noise.
Separator further includes apertured partition 23, and partition 23 is contacted with the end face seal of sleeve member.Pass through partition 23 and sleeve
Part is applied in combination, so that chamber can be separated into the anechoic chamber of different volume sizes by partition 23 along the axial direction of sleeve member, makes
Noise sleeve member axially and radially on can be eliminated, excellent noise reduction effect.
Chamber includes groove body, noise reduction lid 24 and screw 25, and noise reduction lid 24 is fastened on groove body, and screw 25 passes through noise reduction lid 24
It is connect with groove body bottom thread.Chamber is combined compositions using active connection, easy to dismantle and assembly, and to internal zero
Part is replaced and is repaired.
Groove body wall and noise reduction lid 24 are equipped with noise reduction lid through-hole 241, the inlet channel of noise reduction lid through-hole 241 and chamber or go out
The connection of gas channel.By the way that air inlet or outlet are arranged on groove body and noise reduction lid 24, gas is extended in the chamber indoor residence time,
Causing the gas pulsation frequency of discharge reduces, and also achievees the purpose that reduce exhaust noise.
25 outer diameter of screw is less than the aperture on partition 23, screw 25 directly through the hole on partition 23, with groove body bottom into
In addition row connection, avoids apertured again.
Cylinder holder assembly further includes resonance cylinder 26, and resonance cylinder 26 is set in sleeve member, as shown in Figures 4 and 5, on partition 23
In addition an exhaust hole 231 is added, is not provided with through-hole in resonance cylinder 26, entire noise reduction chamber is separated into a resonator chamber
With two noise reduction chambers, compared with the identical casting silencing cavity of traditional single volume size, not only noise reduction frequency band is widened, but also
Resonant cavity can eliminate the noise peak of specific frequency point, in the case where meeting gettering efficiency, and then further decrease exhaust
Noise.
Another embodiment of the present invention, a kind of pump assembly, including cylinder holder assembly as described above.
Pump assembly of the present invention offers exhaust hole 11 (aperture 3mm) in cylinder head end face, sets in exhaust noise silencing chamber 2
There are two sleeve, it is provided at 21 sheet metal component of outer sleeve outer sleeve through hole 211 (aperture 3mm, wall thickness are 1mm~1.5mm), it is interior
It is also equipped at 22 sheet metal component of sleeve inner sleeve through-hole 221 (aperture 2mm, wall thickness are 1mm~1.5mm), is opened on noise reduction lid 24
Equipped with inside exhaust pipe hole (aperture 3.2mm), gas becomes the gas of high temperature and pressure by the compression of cylinder, enters cylinder head
High pressure chest in, then along 1 cylinder head end face of cylinder block exhaust hole 11 enter, then again from outer sleeve through hole 211 enter
Second anechoic chamber is entered to an anechoic chamber, then from inner sleeve through-hole 221, is entered finally into third anechoic chamber, from
Inside exhaust pipe is drained into inside exhaust pipe in hole.Under inside exhaust pipe size and the identical situation of length, the gas of high temperature and pressure
It is discharged from casting silencing cavity, the time for entering inside exhaust pipe road is long, and then the gas wave being discharged from exhaust noise silencing chamber 2
Dynamic frequency reduces, so as to reduce noise.
Compared with the identical casting silencing cavity of traditional single volume size, the exhaust noise silencing chamber of pump assembly of the invention
2 are separated into the expansion anechoic chamber of three different volume sizes, on the one hand increase noise reduction frequency band, still further aspect extends gas
Body flow cycle, increases the transmitting loss of gas, and then reduces exhaust noise, and erasure effect is good.
Yet another embodiment of the invention, a kind of air conditioner, including pump assembly as described above.Specifically, the pump of air conditioner
The pump assembly is equipped in body, which further includes connecting rod 3, crankshaft 4, piston 5 and motor 6.
By increasing partition 23 and inside and outside sleeve sheet metal component at casting silencing cavity, casting noise reduction chamber is divided into multiple
The different anechoic chamber of volume size increases the noise reduction frequency range of anechoic chamber, noise reduction compared with traditional level-one exhaust noise silencing chamber 2
Frequency band is widened, and furthermore by the through-hole of inside and outside sleeve sheet metal component, extends gas and enters time consumed in inside exhaust pipe, from row
The vibration frequency that gas is discharged in gas silencing cavity 2 reduces, to reduce exhaust noise.
Those skilled in the art will readily recognize that the respective embodiments described above can be free under the premise of not conflicting
Ground combination, superposition.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
