Referring to Fig. 6 A, Fig. 6 B, Fig. 8 and Figure 10, in some embodiments, when first shell parts walls 28 include relative to When the second part 38 for the inner surface 34 that axis A is radially recessed from the first part 36 of inner surface 34, second shell parts walls 50 Resonator aperture 72 is jointly limited with the first part 36 of the inner surface 34 of first shell parts walls 28.In such embodiment In, the first part of the first wall end 52 and first shell parts walls 28 of second shell parts walls 50 as shown in Figure 6 A and 6 B 36 are axially spaced, and thus define resonator aperture 72.In the embodiment shown, resonator aperture 72 has annular Configuration.It is to be understood, however, that resonator aperture 72 can have arc configuration.For example, the of second shell parts walls 50 The only a part of one wall end 52 can be axially spaced with the first part 36 of first shell parts walls 28, and second shell The first part 36 of the other parts apical grafting first shell parts walls 28 of first wall end 52 of parts walls 50.

Referring to Fig. 6 C, in other embodiments, when first shell parts walls 28 include relative to axis A from inner surface 34 When the second part 38 for the inner surface 34 that first part 36 is radially recessed, only the first part 36 of first shell parts walls 28 is limited Determine resonator cavities 72.In such embodiments, 52 apical grafting of the first wall end of second shell parts walls 50 as shown in Figure 6 C The first part 36 of first shell parts walls 28.Resonator aperture 72 can have loop configurations or arc configuration.

Referring to Fig. 6 D, in yet other embodiment, when first shell parts walls 28 include relative to axis A from interior table When the second part 38 for the inner surface 34 that the first part 36 in face 34 is radially recessed, only second shell parts walls 50 limit resonance Device cavity 72.In such embodiments, the 52 apical grafting first shell of the first wall end of second shell parts walls 50 as shown in Figure 6 D The first part 36 of body component wall 28.Resonator aperture 72 can have loop configurations or arc configuration.

When first shell component 26 includes shield wall 40, the shield of second shell parts walls 50 and first shell parts walls 28 Cover wall 40 can jointly limit resonator aperture 72.In such embodiments, second shell portion as shown in figures 12 and 14 The first wall end 52 and the shield wall 40 of part wall 50 are axially spaced, and thus limit resonator aperture 72.In the reality shown It applies in example, resonator aperture 72 has loop configurations.It is to be understood, however, that resonator aperture 72 can have arc structure Type.For example, the only a part of the first wall end 52 of second shell parts walls 50 can be axially spaced with shield wall 40, The shield wall 40 of the other parts apical grafting first shell parts walls 28 of first wall end 52 of middle second shell parts walls 50.

Referring to Fig.1 1, when shield wall 40 is included in first shell component 26, shield wall 40 is in first end 42 and second It can be between end 44 continuous.When shield wall 40 is continuous between first end 42 and the second end 44, shield Wall 40 itself will not limit any resonator aperture.But 40 He of shield wall of first shell component 26 as described above Second shell parts walls 50 jointly limit resonator aperture 72.In other embodiments, shield wall 40 first end 42 with It can be between the second end 44 continuously and only second shell component 46 can limit resonator aperture 72.For example, only There are second shell parts walls 50 that can limit resonator aperture 72.In some embodiments, shield wall 40 first end 42 with It can be between the second end 44 continuously, and only first shell parts walls 28 can limit resonator aperture 72.

In other embodiments, when shield wall 40 includes in first shell component 26, only shield wall 40 is limited humorous Shake device aperture 72.In other words, shield wall 40 can not be continuously between first end 42 and the second end 44, but can be with Limit resonator aperture 72.

Referring again to Fig. 4, the company of can be between the first wall end 52 and the second wall end 54 of second shell parts walls 50 Continuous.When second shell parts walls 50 are continuous between the first wall end 52 and the second wall end 54, second shell portion Part wall 50 itself will not limit any resonator aperture.But second shell parts walls 50 and first shell component 26 are jointly Limit resonator aperture 72.Specifically, second shell parts walls 50 can as described above with first shell parts walls 28 Second part 38 or the shield wall 40 of first shell component 26 jointly limit resonator aperture 72.In other embodiments In, second shell parts walls 50 can be continuous and first shell portion between the first wall end 52 and the second wall end 54 Part 26 can limit alone resonator aperture 72.In such embodiments, only first shell parts walls 28 and/or first shell The shield wall 40 of body component 26 can limit resonator aperture 72.In yet other embodiment, only second shell component Wall 50 limits resonator aperture 72.In other words, second shell parts walls 50 are between the first wall end 52 and the second wall end 54 It can not be continuous but resonator aperture 72 can be limited.

During turbocharger 20 operates, air flows through compressor housing entrance 30, passes through resonator aperture 72 And it flow in resonator cavities 64, wherein air passes through resonator aperture 72 later and flow in 64 internal vibration of resonator cavities Return to compressor housing entrance 30.In addition, 72 resonator cavity 64 of resonator aperture is sized to from compression case Body entrance 30 receives the air with certain acoustic wavelength.For example, the size of 72 resonator cavity 64 of resonator aperture can be with Be determined to be from compressor housing entrance 30 receive have typically with fizz (that is, air pass through compressor housing entrance The 30 undesirable noises occurred when flowing to compressor impeller 24 and/or vibration) associated acoustics wavelength air.With this Mode, resonator aperture 72 resonator cavity 64 improve the turbocharger 20 during turbocharger 20 operates and make an uproar Sound, vibration and sound vibration roughness (NVH) feature, especially when turbocharger 20 is used in automotive vehicles applications.

As described above, the size of 72 resonator cavity 64 of resonator aperture, which can be determined to be reception, has spy Determine the air of acoustics wavelength.For this reason, it should be appreciated that 72 resonator cavity 64 of resonator aperture can be based on The specific application of turbocharger 20 and harmful noise associated with specific application and vibration are to determine size.Change speech It, can be based on the certain acoustic wavelength being intended to filter out come the cross-sectional flow area resonator cavity in selective resonance device aperture 72 64 volume, so that certain acoustic wavelength no longer generates harmful noise and vibration during turbocharger 20 operates.

Though not requiring, in some embodiments, compressor housing component 22 does not have other than resonator aperture 72 Any resonator aperture additional, that resonator cavities 64 are fluidly coupled to compressor housing entrance 30.In other words, only humorous Resonator cavities 64 are fluidly coupled to compressor housing entrance 30 by vibration device aperture 72.In such embodiments, from compression The air of machine housing inlet port 30 only can flow in resonator cavities 64 via resonator aperture 72 and flow out resonator cavity Body.

In some embodiments, compressor housing component 22 is without any axial relative to axis A and resonator aperture 72 Additional resonator aperture that ground is spaced apart and that resonator cavities 64 are fluidly coupled to compressor housing entrance 30.Example Such as, referring to Fig. 6 A and Fig. 6 B, when the second part 38 of second shell parts walls 50 and first shell parts walls 28 limits resonator When aperture 72, between second shell parts walls 50 and first shell parts walls 28 do not limit any and resonator aperture 72 axially Additional resonator aperture separate and that resonator cavities 64 are fluidly coupled to compressor housing entrance 30.

When compressor housing component 22 it is not any be axially spaced with resonator aperture 72 relative to axis A it is additional Resonator aperture when, it should be appreciated that first shell parts walls 28, second shell parts walls 50, and/or shield wall 40 can With the resonator aperture 72 weeks for jointly or independently limiting with resonator cavities 64 being fluidly coupled to compression shell entrance 30 The additional resonator aperture being spaced apart to ground.
