Each orifice element has a plate body, a connecting element, and a support pin. A transmission ring is mechanically connected to the plurality of orifice elements via the connecting element. One of these orifice elements is configured to drive the orifice element. The support pin of the driving orifice element is configured as an elongated support pin.

Description

Technical Field

[0001] This disclosure relates to an adjustment mechanism for adjusting the cross-section of a compressor inlet. Furthermore, the present invention relates to adjustment components, compressors, and booster equipment having such adjustment mechanisms. Background Technology

[0002] The personal mobility sector is undergoing disruptive change. In particular, the increasing number of electric vehicles entering the market and stricter emissions regulations from legislators requiring conventional internal combustion engine (ICE) vehicles to be more efficient are driving this trend. Consequently, more and more vehicles are equipped with efficiency-enhancing measures such as supercharging and emissions reduction devices. Supercharging, for example, is well-known, where the compressor can be driven by an electric motor (electric inflator) and / or a turbine powered by exhaust gas (turbocharger).

[0003] Therefore, a typical compressor consists of a compressor housing and a compressor impeller arranged within the housing. During operation, air is drawn through the compressor inlet of the housing, accelerated and compressed by the compressor impeller, and then exits the compressor via the volute of the compressor housing. Each compressor has its own compressor characteristic profile that defines its operating range. In the compressor profile, this operating range is primarily defined by surge lines and blockage lines.

[0004] To further improve the efficiency of an ICE (Insulated Air Conditioner), it is well known to improve the compressor profile, for example by preventing surge, i.e., taking measures to shift the surge line to the left. This can be achieved, for example, through a compressor inlet regulating mechanism. Common regulating mechanisms are configured to, for example, increase airflow velocity, modify the flow angle, or establish a flow path for recirculation. When referring to increasing airflow velocity, it is known to reduce the inlet diameter of the compressor inlet by an orifice element moved by an actuator ring. The actuator ring itself is typically coupled to multiple intermediate elements such as a lever assembly, and is moved by said multiple intermediate elements via an actuator. These measures and elements typically require space, may increase weight, may lead to increased production costs, and may increase maintenance requirements due to wear.

[0005] Therefore, the object of the present invention is to provide an improved compressor inlet regulating mechanism. Summary of the Invention

[0006] This invention relates to an adjustment mechanism. Furthermore, this invention relates to a corresponding adjustment mechanism, a compressor, and a corresponding pressurization device including the adjustment mechanism.

[0007] An inventive adjusting mechanism for variably adjusting the cross-section of a compressor inlet includes a plurality of rotatable orifice elements and a drive ring. Each orifice element has a plate body, a connecting element, and a support pin. The drive ring is mechanically connected to the plurality of orifice elements via the connecting element. One of these orifice elements is configured to drive the orifice element. The support pin of the drive orifice element is configured as an elongated support pin. The elongated support pin is configured to be longer than the support pins of the other orifice elements. Furthermore, the elongated support pin is adapted to be connected to an actuation system such that when the drive orifice element is moved by the actuation system, the movement is transmitted from the drive orifice element to the other orifice elements via the drive ring. Compared with known adjusting mechanisms, the inventive configuration of the adjusting mechanism results in a different force flow. Rotation of the elongated support pin directs the actuating force directly from the actuation system to the drive orifice element. Thus, the drive orifice element, together with its connecting element, can pivot. The connecting element of the drive orifice element then interacts with the drive ring, causing the drive ring to rotate. Force is transmitted from the drive orifice element to other orifice elements via a drive ring, causing pivotal movement of the orifice elements to adjust the cross-section of the compressor inlet. The orifice elements are distributed circumferentially along the drive ring. Optionally, the orifice elements can be configured and arranged such that they can contact their respective adjacent orifice elements in the circumferential direction. Thus, for example, in addition to force transmission via the drive ring, the drive orifice element can also push adjacent orifice elements during movement. Orifice elements adjacent to the drive orifice element can in turn push their respective adjacent orifice elements. This allows for a direct force transmission process from one orifice element to another. The auxiliary direct force transmission from the drive orifice element to its adjacent orifice element (and to its adjacent orifice element) improves the dynamics of the regulating mechanism, particularly by supporting the initial movement of the drive ring. The inventive configuration of the drive orifice elements eliminates the need for lever assemblies or other intermediate components used in known systems. Therefore, this results in fewer required components, reduced space requirements, better packaging, and lower manufacturing costs.

[0008] In one aspect of the adjusting mechanism, the support pin is arranged radially further outside the corresponding orifice element than the connecting element. Specifically, the support pin is arranged radially further outside the plate body than the connecting element. Alternatively, the connecting element is arranged in the radially intermediate portion of the corresponding orifice element. Alternatively, the support pin is arranged in the radially outer portion of the corresponding orifice element. Specifically, the support pin is arranged at the radially outer end of the corresponding orifice element. By arranging the support pin radially outside the connecting element, the travel distance of the corresponding connecting element relative to the drive ring can be reduced. This reduces the potential wear of each connecting element and the wear of the drive ring. In particular, the increased distance between the connecting element and the corresponding support pin of an orifice element reduces the relative movement between each connecting element and the drive ring. Furthermore, by arranging the support pin radially outside the connecting element (i.e., arranging the support pin further away from the compressor axis in the radially outer direction), the movement of the plate body between the open and closed positions requires less rotation of the entire orifice element. This also results in less wear.

[0009] In another aspect, which can be combined with the foregoing, the connecting element and the support pin can protrude directly from the plate body of the corresponding orifice element in the axial direction. In other words, the connecting element and the support pin are integrally formed with the plate body.

[0010] In another aspect, which can be combined with any of the foregoing aspects, each orifice element may have an upstream surface and a downstream surface. The upstream surface points upstream in a first axial direction. The downstream surface points downstream in a second axial direction opposite to the first axial direction.

[0011] In another aspect that can be combined with the foregoing, the connecting element may extend from the upstream surface in a first axial direction. Alternatively, the connecting element may extend from the downstream surface in a second axial direction.

[0012] As a supplement or alternative to the previous aspects, the drive ring can be arranged axially adjacent to the upstream surface or adjacent to the downstream surface.

[0013] As a supplement or alternative to the previous aspects, the connecting element and the drive ring can be arranged on the same side of the upstream or downstream side.

[0014] As a supplement or alternative to the previous aspect, the elongated support pin can always be arranged on the upstream side. The elongated support pin can extend from the upstream surface in the first axial direction.

[0015] As a supplement to or alternative to the preceding aspects, the support pins of other orifice elements may extend from the upstream surface in the first axial direction. Alternatively, the support pins of other orifice elements may extend from the downstream surface in the second axial direction.

[0016] In another aspect, which can be combined with any of the foregoing aspects, the drive ring may have a plurality of circumferentially arranged grooves. Each connecting element may be operatively coupled to a corresponding groove. Furthermore, each groove may have a longitudinal shape extending in a substantially radial direction. Thus, each connecting element may slide radially within a corresponding groove. Moreover, movement between the drive ring and the orifice element may be transmitted in the circumferential direction.

[0017] In another aspect, which can be combined with any of the foregoing aspects, the adjusting mechanism may further include a housing portion. Additionally, the housing portion may have a hole. Furthermore, an elongated support pin may extend through the hole to connect to an actuation system outside the housing portion. Additionally, the housing portion may be an inlet port defining the compressor inlet.

[0018] The invention further relates to an adjustment assembly for variably adjusting the cross-section of a compressor inlet. The adjustment assembly includes an adjustment mechanism according to any of the foregoing aspects. Furthermore, the adjustment assembly includes an actuation system. The actuation system is configured to actuate a drive orifice element. This means that the drive orifice element is operatively coupled to the actuation system. The actuation system may include a drive unit. The drive unit is configured as a rotary drive unit. Additionally, a first toothed structure may be arranged in a first end portion of an elongated support pin. Furthermore, the adjustment assembly may further include a first toothed element. The first toothed element may be arranged at the first end portion and may include the first toothed structure. The first toothed element may be rotatably attached to the first end portion. The first toothed structure may be arranged on a radial surface of the elongated support pin or on a radial surface of the toothed element (i.e., the surface pointing radially relative to the elongated support pin). In embodiments including the first toothed element, the length of the toothed element relative to the elongated support pin in the radial direction may be configured to place the actuation system closer to or further away from the elongated support pin. In other words, by providing the first toothed element, the distance between the actuation system and the elongated support pin and / or housing portion can be adjusted. This allows for flexible placement of the actuation system by appropriately configuring the first toothed element. Furthermore, it provides the possibility of using different actuation systems (e.g., actuation systems of different sizes). In other words, the first toothed structure can be directly disposed in the elongated support pin or disposed in an additional element (i.e., the first toothed element). If the first toothed structure is formed directly on the elongated support pin, it can optionally be arranged in a toothed recess of the elongated support pin. The toothed recess can be formed in the end face of the elongated support pin. Thus, the actuation system can be directly coupled to the elongated support pin in a very compact manner. The actuation system can be arranged closer to the housing portion. Therefore, a more compact device can be provided.

[0019] In another aspect of the adjustment assembly, the first toothed structure can extend at least along the arc length of the sector. Furthermore, the sector can be defined by a central angle θ1 between 5° and 360°, preferably between 10° and 60°, and especially between 15° and 45°. By adjusting the central angle θ1 to less than 360°, a full rotation is not required. Moreover, manufacturing costs can be reduced because a smaller area is required in the toothed configuration.

[0020] As a supplement or alternative to the preceding aspects, the adjusting assembly may further include a second toothed structure. The second toothed structure may be formed to complement the first toothed structure and may be operatively coupled to the drive unit. Furthermore, the second toothed structure may engage with the first toothed structure to rotate the elongated support pin. In other words, the actuation system may include the second toothed structure. Additionally, the adjusting assembly may further include a rotatable drive shaft. The rotatable drive shaft may be operatively coupled to the drive unit. This means that the actuation system may include a rotatable drive shaft. Furthermore, the second toothed structure may be formed directly on the rotatable drive shaft. Specifically, the second toothed structure may be formed directly in the second shaft end portion of the rotatable drive shaft. If the second toothed structure is formed directly on the rotatable drive shaft, the second toothed structure may optionally be arranged in a toothed recess of the rotatable drive shaft. The toothed recess may be formed in the shaft end face of the rotatable drive shaft. Thus, the actuation system can be directly coupled to the elongated support pin in a very compact manner. The actuation system can be arranged closer to the housing portion. Therefore, a more compact device can be provided. As an alternative to being directly formed on the rotatable drive shaft, the adjustment assembly (i.e., the actuation system) may further include a second toothed element, which includes a second tooth profile. The second toothed element is operatively coupled to the drive unit. The second toothed element may be arranged on the rotatable drive shaft. Specifically, the second toothed element may be arranged in a second shaft end portion of the rotatable drive shaft. Thus, the second toothed element can be operatively coupled to the drive unit via the rotatable drive shaft. Additionally, the second toothed element can be rotatably attached to the rotatable drive shaft.

[0021] In another aspect of the adjustment assembly that can be assembled with the foregoing aspects, the second toothed structure can extend at least along the arc length of the sector. Furthermore, the sector can be defined by a central angle θ2 between 5° and 360°, preferably between 10° and 60°, and especially between 15° and 45°.

[0022] As an alternative to the aforementioned aspects, the second toothed element is configured as a rack.

[0023] The present invention further relates to a compressor for a booster device. The compressor includes a compressor housing, an impeller, and an adjustment assembly according to any of the foregoing aspects. The compressor housing defines a compressor inlet and a compressor outlet. The impeller is rotatably mounted in the compressor housing between the compressor inlet and the compressor outlet. Additionally, if the adjustment mechanism includes a housing portion, the housing portion is part of the compressor housing. Furthermore, the housing portion forms the compressor inlet. In other words, the housing portion serves as the inlet port of the compressor. Thus, the housing portion can be attached to the compressor housing. The housing portion can be arranged upstream of the impeller.

[0024] The present invention further relates to a booster device. The booster device includes a compressor drive unit and a compressor, as described in any of the foregoing aspects. The compressor is rotatably connected to the compressor drive unit via a shaft.

[0025] In one aspect of the booster device, the compressor drive unit may include a turbine. Alternatively, the compressor drive unit may include an electric motor. Attached Figure Description

[0037] In the context of this invention, the terms "axially," "axially," or "axial direction" refer to a direction parallel to or along the axis of the drive ring (i.e., the axis of rotation). When the adjusting mechanism is installed in the compressor housing, the axial direction also substantially coincides with the axis of the compressor, i.e., with the axis of rotation of the compressor impeller. Therefore, reference is made to the accompanying drawings, and particularly to... Figure 2A and Figure 6 The axial dimension is described by reference numeral 22, and the radial dimension extending "radially" away from the axial dimension 22 is described by reference numeral 24. Additionally, the circumferential dimension surrounding the axial dimension 22 is described by reference numeral 26. If the axial, radial, or circumferential direction / dimension is to be understood in a manner different from that just described, it is explicitly indicated (e.g., radially from the axis of the elongated support pin).

[0038] Figure 1 An inventive booster device 400, comprising a compressor 300 and a compressor drive unit 410, is schematically shown. The compressor 300 is rotatably connected to the compressor drive unit 410 via a shaft 420. Figure 1 In an exemplary embodiment, the compressor drive unit 410 is configured as an exhaust turbine. However, in an alternative embodiment, the compressor drive unit 410 may be configured as an electric motor, or a combination of an exhaust turbine and an electric motor. The compressor 300 includes a compressor housing 310 and an impeller 320. The compressor housing 310 defines a compressor inlet 312 and a compressor outlet 314. The impeller 320 is rotatably mounted in the compressor housing 310 between the compressor inlet 312 and the compressor outlet 314. Furthermore, the compressor 300 includes an adjustment assembly 30. The adjustment assembly 30 includes an adjustment mechanism 10 and an actuation system 230.

[0039] refer to Figure 2A and Figure 2BThe adjustment mechanism 10 for variably adjusting the cross section 312a of the compressor inlet 312 will be explained in more detail. The adjustment mechanism 10 includes a plurality of rotatable orifice elements 100, 100' and a drive ring 210. Each orifice element 100, 100' has a plate body 130, a connecting element 110, and support pins 120, 120'. The drive ring 210 is mechanically connected to the plurality of orifice elements 100, 100' via the connecting element 110 (see details...). Figure 2B One of these orifice elements 100, 100' is configured to drive orifice element 100'. The support pin 120' of the drive orifice element 100' is configured as an elongated support pin 120'. The elongated support pin 120' is configured to be longer than the support pins 120 of the other orifice elements 100. Furthermore, the elongated support pin 120' is adapted for coupling to an actuation system 230 (not depicted here, see, for example, ...). Figure 4B or Figure 5A The adjustment assembly 30 in the actuation system 230 transmits movement from the drive orifice element 100' to other orifice elements 100 via the transmission ring 210 when the drive orifice element 100' is moved by the actuation system 230. Therefore, for example, the length of the elongated support pin 120' is adapted to be sufficiently long to be coupled to the actuation system 230. Other adaptation structures of the elongated support pin 120' will be described later with reference to the adjustment assembly 30. The inventive configuration of the adjustment mechanism 10 results in a different force flow compared to known adjustment mechanisms. Rotation of the elongated support pin 120' directs the actuating force directly from the actuation system 230 to the drive orifice element 100'. Thus, the drive orifice element 100', together with its connecting element 110, can pivot. Specifically, the drive orifice element 100' can pivot about the axis of the elongated support pin 120'. The connecting element 110 of the drive orifice element 100' then interacts with the transmission ring 210, causing the transmission ring 210 to rotate. Force is transmitted via drive ring 210 from drive orifice element 100' to other orifice elements 100, thereby causing pivotal movement of orifice element 100 (about the corresponding axis of its respective support pin 120) to adjust the cross section 312a of compressor inlet 312. Therefore, adjusting mechanism 10 can move between an open position or open state and a closed position or closed state, in which the cross section 312a of compressor inlet 312 is maximized, and in the closed position or closed state, the cross section 312a of compressor inlet 312 is reduced. This is in Figure 3A and Figure 3B It was shown in the middle. Figure 3A The diagram shows the open state of the adjusting mechanism 10, in which the orifice elements 100, 100' pivot radially outward, i.e., radially away from the center of the drive ring 210 (see the arrow indicating the axial direction 22). Conversely, Figure 3AThe diagram shows the closed state of the regulating mechanism 10, in which the orifice elements 100, 100' pivot radially inward, i.e., radially toward the center of the drive ring 210. In this closed state, the orifice elements 100, 100' (i.e., their respective plate bodies 130) can block the radially outer portion of the cross-section 312a of the compressor inlet 312, thereby reducing the cross-section 312a. For a better understanding of the following explanation, reference is also made to a more clearly depicted illustration of this function. Figure 7 The figure shows an adjustment mechanism 10 installed in the compressor housing 310. It is evident here that when the adjustment mechanism 10 is depicted as being in a closed state, the orifice elements 100, 100' block a portion of the compressor inlet 312, thereby reducing the cross-section 312a of the compressor inlet 312.

[0040] Refer again Figure 3A and Figure 3B As can be seen, the orifice elements 100 and 100' are distributed along the drive ring 210 in the circumferential direction 26. The orifice elements 100 and 100' are configured and arranged such that they contact their respective adjacent orifice elements 100 and 100' in the circumferential direction 26. This physical contact allows the drive orifice element 100' to push the adjacent orifice element 100 during movement. In addition to the force transmission through the drive ring 210, this "direct push movement" can also be applied to the adjacent orifice elements 100. Those orifice elements 100 adjacent to the drive orifice element 100' can in turn push their respective adjacent orifice elements 100. This enables a direct force transmission process from one orifice element 100 and 100' to another orifice element 100 and 100'. The auxiliary direct force transmission from the drive orifice element 100' to its adjacent orifice element 100 (and to its adjacent orifice element) can improve the dynamics of the adjustment mechanism 10. Specifically, it can support the initial movement of the drive ring 210. The inventive configuration of the drive orifice element 100', which can be directly coupled to the actuation system 230, eliminates the need for lever assemblies or other intermediate components used in known systems. This results in fewer required components, less space requirements, better packaging, and lower manufacturing costs.

[0041] Further reference Figure 2B and Figure 3BEach orifice element 100, 100' (more specifically, each plate body 130) includes a radially intermediate portion 136, a radially outer portion 138, and a radially outer end portion 138a. The radially intermediate portion 136 is part of the plate body 130 and is located in the radially intermediate region of the plate body 130 when the adjustment mechanism 10 is in the closed state. The radially outer portion 138 is part of the plate body 130 and is located in the radially outer region of the plate body 130 when the adjustment mechanism 10 is in the closed state. The radially outer end portion 138a is part of the plate body 130 and is located at the radially outer end of the plate body 130 when the adjustment mechanism 10 is in the closed state. When the adjustment mechanism 10 moves to the open state, the corresponding portions 138 and 138a also move accordingly, but remain fixed relative to the corresponding plate body 130. Each corresponding support pin 120, 120' is arranged at the radially outer end 138a of the corresponding orifice element 100, 100' (see, for example, Figure 3B Each corresponding connecting element 110 is arranged in the radial intermediate portion 136 of the corresponding orifice element 100, 100' (see, for example, Figure 2B Alternatively, the support pins 120, 120' may also be arranged in the radially outer portions 138 of the respective orifice elements 100, 100, and do not need to be precisely arranged at the radially outer ends 138a. However, in all embodiments, the support pins 120, 120' are preferably arranged radially further outside the respective orifice elements 100, 100' than the connecting element 110. By arranging the support pins 120, 120' radially outside the connecting element 110, the travel distance of the respective connecting element 110 relative to the drive ring 210 can be reduced. This reduces the potential wear of each connecting element 110 and the potential wear of the drive ring 210. In particular, the increased distance between the connecting element 110 and the respective support pins 120, 120' of the respective orifice elements 100, 100' reduces the relative movement between each connecting element 110 and the drive ring 210. Furthermore, by arranging the support pins 120, 120' radially outside the connecting element 110 (i.e., further away from the compressor axis in the radially outward direction 24), the movement of the plate body 130 between the open and closed positions requires only minor rotation of the entire orifice element 100, 100'. This also reduces wear, particularly the wear of the support pins 120, 120'.

[0042] like Figure 2A and Figure 2BAs depicted, each orifice element 100, 100' has an upstream surface 132 and a downstream surface 134. More specifically, each plate body 130 of the corresponding orifice element 100, 100' has an upstream surface 132 and a downstream surface 134. The upstream surface 132 points towards the upstream side 132a of the regulating mechanism 10 in a first axial direction 22a. The downstream surface 134 points towards the downstream side 134a of the regulating mechanism 10 in a second axial direction 22b opposite to the first axial direction 22a. Thus, the first axial direction 22a extends in opposite directions to the second axial direction 22b. Generally, the upstream side 132a and the downstream side 134a are defined by the flow direction of the fluid flowing through the compressor in the assembled state of the regulating mechanism in the compressor 300 during operation. Therefore, see also Figure 7 The figure shows the adjustment mechanism 10 assembled in the compressor housing 310, and the upstream side 132a and the downstream side 134a are illustrated with respect to the adjustment mechanism 10.

[0043] The connecting element 110 and the support pins 120, 120' typically protrude directly from the plate body 130 of the corresponding orifice element 100, 100' in the axial direction 22. In the illustrated embodiment, the support elements 120, 120' extend from the plate body 130 of the corresponding orifice element 100, 100' in the first axial direction 22a. In other words, the connecting element 110 and the support pins 120, 120' are integrally formed with the corresponding plate body 130 of one orifice element 100, 100'. The connecting element 110 extends from the plate body 130 of the corresponding orifice element 100, 100' in the second axial direction 22b. The drive ring 210 is axially arranged adjacent to the downstream surface 134 of the orifice element 100, 100'. In other words, the drive ring 210 is axially arranged adjacent to the downstream surface 134 of the plate body 130. The drive ring 210 has a plurality of circumferentially arranged grooves 212 (see...). Figure 2B and Figure 3BEach connecting element 110 is operatively coupled to a corresponding groove 212. Each groove 212 has a longitudinal shape extending in a generally radial direction 22. Thus, each connecting element 110 can slide within the corresponding groove 212 in the radial direction 22. Therefore, the connecting element 110 engages with the corresponding groove 212. This means that the drive ring 210 needs to be arranged on the same side of the plate body 130 as the connecting element 110. Thus, movement can be transmitted between the drive ring 210 and the orifice elements 100, 100' in the circumferential direction 26. Alternatively, the connecting element 110 can extend from the upstream surface 132 (not depicted) in a first axial direction 22a to extend from the downstream surface 134 in a second axial direction 22b. In this case, the drive ring 210 can also be axially arranged adjacent to the upstream surface 132 of the plate body 130. Preferably, the drive ring 210 and the connecting element 110 are axially arranged adjacent to the downstream side 134, as this allows the adjusting mechanism 10 to have good stability during movement. Arranging the drive ring 210 and connecting element 110 on the upstream side 132a allows for a more compact device. The elongated support pin 120' must always be arranged on the upstream side 132a. In other words, the elongated support pin 120' must always extend from the upstream surface 132 in the first axial direction 22a. This makes the actuation system 230 more easily accessible. However, in an alternative embodiment, some or all of the support pins 120 of the other orifice elements 100 may extend from the downstream surface 134 in the second axial direction 22b. In embodiments where some or all of the support pins 120, 120' are arranged on the same side of the plate body 130 as the drive ring 210, the corresponding support pins need to be radially arranged outside the drive ring 210. Support pins 120, 120' arranged on the side of the plate body 130 opposite to the drive ring 210 do not necessarily need to be radially arranged outside the drive ring 210.

[0044] like Figure 4A and Figure 4B As depicted, the regulating mechanism 10 further includes a housing portion 220 having an inlet portion 226 and a flange portion 228. The housing portion 220 can serve as an inlet port of the compressor 300 and defines a compressor inlet 312. The housing portion 220 includes a bore 222 configured to receive an elongated support pin 120'. The bore 222 extends through the flange portion 228 in the axial direction 22. In other words, the elongated support pin 120' extends through the bore 222 to be coupled to an actuation system 230 outside the housing portion 220. Optionally, a bushing (not depicted) can be arranged in the bore 222 and can rotatably support the elongated support pin 120'. Figure 5B and Figure 7As shown, housing portion 220 further includes a plurality of circumferentially distributed support holes 224. The support holes 224 receive support pins 120. Alternatively, if the support pins 120 are oriented in the opposite direction, i.e., if the support pins 120 extend from the body plate 130 in the second axial direction 22b, the support holes 224 may not be provided in housing portion 220. Instead, the corresponding support holes 224 may be provided directly in compressor housing 310. Alternatively, an additional support ring (not depicted) having a plurality of circumferentially distributed support holes 224 may be provided between compressor housing 310 and orifice elements 100, 100' or between housing portion 220 and orifice elements 100, 100' to support the support pins 120 of orifice elements 100.

[0045] The present invention further relates to an adjustment assembly 30 for variably adjusting the cross section 312a of the compressor inlet 312 (see [link]). Figure 4A The adjustment assembly 30 includes an adjustment mechanism 10 having a housing portion 220. Additionally, the adjustment assembly 30 includes... Figures 4A to 5B The actuation system 230 is schematically depicted. The actuation system 230 is configured to actuate the drive orifice element 100'. This means that the drive orifice element 100' is operatively coupled to the actuation system 230. The actuation system 230 includes a drive unit 234, also schematically depicted only. The drive unit 234 is configured as a rotary drive unit. This means that the drive unit produces rotary driven movement. This can help further reduce the space requirements of the adjustment assembly 30. In some alternative embodiments, the drive unit 234 may be configured as a translational drive unit, i.e., the drive unit produces translational driven movement. An example of this is an instance where the actuation system 230 includes a rack, which will be further explained below. For illustrative purposes, the actuation system 230 is depicted as... Figure 4A and Figure 4B The drive orifice element 100' is kept at a distance and is not connected. Therefore, the function of the drive orifice element 100' becomes clearer. Specifically, in Figure 4B As can be seen, the elongated support pin 120' extends through the housing portion 220. However, it should be understood that in the assembled state, the actuation system 230 is coupled (i.e., physically coupled) to the drive orifice element 100' (see [reference]). Figure 5A and Figure 5B ). Here in Figure 5A and 5BIn this embodiment, the actuation system 230 is directly coupled to the elongated support pin 120'. Therefore, the actuation system 230 is arranged on the elongated support pin 120'. In other words, the elongated support pin 120' extends into the actuation system 230. In the exemplary embodiment, the actuation system 230 is arranged directly at the housing portion 220. This configuration makes the assembly extremely compact. For illustrative purposes, only the flange portion 228 of the housing portion 220 is depicted in these figures, but the housing portion 220 also includes the inlet portion 226 as further explained above. Further reference... Figure 5A and Figure 5B The adjusting assembly may additionally include a seal 250 disposed between the housing portion 220 and the elongated support pin 120'. The seal 250 may, for example, be configured as a sealing ring. Figure 5A and Figure 5B In one embodiment, the actuation system 230 is mounted to the housing portion 220. A seal 250 is disposed between the actuation system 230 and the housing portion 220. In an alternative embodiment, the actuation system 230 does not need to be directly mounted at the housing portion 220. Specifically, in this case, the seal 250 may be disposed between the housing portion 220 and the elongated support pin 120', as described above. For example, the seal 250 may be disposed in or at the hole 222.

[0046] refer to Figures 9A to 9C The elongated support pin 120' includes a first toothed structure 142. The first toothed structure 142 can be directly disposed in the elongated support pin 120' (see [reference]). Figure 9A and Figure 9B ) or set in an additional element (i.e., the first toothed element 140 (see Figure 9C ))middle.

[0047] When the first toothed structure 142 is directly disposed in the elongated support pin 120', the first toothed structure is arranged in the first end portion 122' of the elongated support pin 120'. The first toothed structure 142 can be configured as an external tooth (see...). Figure 9A ) or internal teeth (see Figure 9BA first toothed structure 142 is arranged on the radial surface of the elongated support pin 120'. This means that the first toothed structure 142 is arranged on the surface of the elongated support pin 120', and the surface points radially outward relative to the axis of rotation of the elongated support pin 120'. When the first toothed structure 142 is configured as an external tooth, the first toothed structure 142 is arranged on the radially outer surface of the elongated support pin 120'. In other words, the first toothed structure 142 is arranged on the surface of the elongated support pin 120', and the surface points radially outward relative to the axis of rotation of the elongated support pin 120'. When the first toothed structure 142 is configured as an internal tooth, the first toothed structure 142 is arranged on the radially inner surface of the elongated support pin 120'. In other words, the first toothed structure 142 is arranged on the surface of the elongated support pin 120', and the surface points radially inward relative to the axis of rotation of the elongated support pin 120'. Therefore, the elongated support pin 120' may include a toothed recess 146. A toothed recess 146 is formed in the end face 122a' of the elongated support pin 120'. A first toothed structure 142 is arranged in the toothed recess 146. By directly providing the first toothed structure 142 in the elongated support pin 120', the actuation system 230 can be directly coupled to the elongated support pin 120' in a very compact manner. The actuation system 230 can be arranged closer to the housing portion 220 (see, for example, Figure 5A and Figure 5B Therefore, a more compact device can be provided.

[0048] Figure 9C An adjustment assembly 30 including a first toothed element 140 is shown. The first toothed element 140 is disposed at a first end portion 122' and includes a first toothed structure 142. The first toothed element 140 is rotatably attached to an elongated support pin 120'. Preferably, the first toothed element 140 is rotatably attached to the first end portion 122'. The first toothed structure 142 is disposed on the radial surface of the first toothed element 140 (i.e., the surface pointing radially relative to the axis of rotation of the elongated support pin 120'). The length of the first toothed element 140 in the radial direction relative to the axis of rotation of the elongated support pin 120' can be configured to place the actuation system 230 closer to or further away from the elongated support pin 120'. In other words, by providing the first toothed element 140, the distance between the actuation system 230 and the elongated support pin 120' and / or the housing portion 220 can be adjusted. This allows for flexible placement of the actuation system 230 by appropriately configuring the first toothed element 140. Furthermore, it provides the possibility of using different actuation systems 230 (e.g., actuation systems 230 of different sizes).

[0049] refer to Figure 9A and Figure 9CThe first toothed structure 142 extends only along the arc length 144a of the sector 144. The sector 144 is defined by a central angle θ1, preferably between 10° and 60°. Alternatively, the central angle θ1 can be a value between 5° and 360°, and particularly between 15° and 45°. Thus, in some embodiments, the first toothed structure 142 may alternatively also extend along the entire circumference of the elongated support pin 120' or the first toothed element 140. The first toothed element 140 may be substantially shaped as a sector 144, or may consist substantially only of a sector 144 (see [link to previous section]). Figure 9C Alternatively, the first toothed element 140 can be formed as a circle (not depicted). By adjusting the central angle θ1 to less than 360°, a full rotation is not required. Furthermore, manufacturing costs can be reduced because a smaller area is required in the toothed configuration.

[0050] refer to Figures 10A to 10D The adjusting assembly 30 includes a second toothed structure 242. More specifically, the actuation system 230 includes the second toothed structure 242. The second toothed structure 242 is engaged with the first toothed structure 142 to rotate the elongated support pin 120'. To achieve this, the second toothed structure 242 is formed to be complementary to the first toothed structure 142. Furthermore, the second toothed structure 242 is operatively coupled to the drive unit 234. Figures 10A to 10C As depicted, the adjustment assembly 30 further includes a rotatable drive shaft 232. More specifically, the actuation system 230 includes the rotatable drive shaft 232. The rotatable drive shaft 232 is operatively coupled to the drive unit 234. A second toothed structure 242 may be directly disposed in the rotatable drive shaft 232 (see [reference]). Figure 10A ) or set in an additional element (i.e., a second toothed element 240 (see Figure 10B and Figure 10C The rotatable drive shaft 232 has a first shaft end portion 233 and a second shaft end portion 235. The first shaft end portion 233 is connected to the drive unit 230. The second shaft end portion 235 is connected to the elongated support pin 120'. More specifically, if a second toothed element 240 is provided, the second shaft end portion 235 is connected to the elongated support pin 120' via the second toothed element 240.

[0051] When the second toothed structure 242 is directly disposed in the rotatable drive shaft 232, the second toothed structure is arranged in the second shaft end portion 235 of the rotatable drive shaft 232. This means that the second toothed structure 242 is directly formed on the rotatable drive shaft 232 (see [reference]). Figure 10A ).exist Figure 10A In this example, the second tooth structure 242 is configured as an internal tooth. Alternatively, the second tooth structure 242 can be configured as an external tooth (in... Figure 10C The external teeth are depicted only along with additional elements, but the external teeth and Figure 9A (Similar to the external teeth in the text). The second tooth structure 242 is arranged on the radial surface of the rotatable drive shaft 232. This means that the second tooth structure 242 is arranged on the surface of the rotatable drive shaft 232, and the surface points radially outward relative to the axis of rotation of the rotatable drive shaft 232. When the second tooth structure 242 is configured as an external tooth, the second tooth structure 242 is arranged on the radially outer surface of the rotatable drive shaft 232. In other words, the second tooth structure 242 is arranged on the surface of the rotatable drive shaft 232, and the surface points radially outward relative to the axis of rotation of the rotatable drive shaft 232. When the second tooth structure 242 is configured as an internal tooth, the second tooth structure 242 is arranged on the radially inner surface of the rotatable drive shaft 232. In other words, the second tooth structure 242 is arranged on the surface of the rotatable drive shaft 232, and the surface points radially inward relative to the axis of rotation of the rotatable drive shaft 232. Therefore, the rotatable drive shaft 232 includes a toothed recess 246. A toothed recess 246 is formed in the shaft end face 235a of the rotatable drive shaft 232. A second toothed structure 242 is arranged in the toothed recess 246. By directly providing the second toothed structure 242 in the rotatable drive shaft 232, the actuation system 230 can be directly coupled to the elongated support pin 120' in a very compact manner. The actuation system 230 can be arranged closer to the housing portion 220 (see, for example, Figure 5A and Figure 5B Therefore, a more compact device can be provided.

[0052] Additionally, when the second toothed element 240 is present, the second toothed structure 242 can be configured as an external tooth (see [reference]). Figure 10C ) or internal teeth (see Figure 10BThe second toothed element 240 includes a second toothed structure 242. The second toothed element 240 is disposed in a second shaft end portion 235 of the rotatable drive shaft 232. The second toothed element 240 is rotatably attached to the rotatable drive shaft 232. Preferably, the second toothed element 240 is rotatably attached to the second shaft end portion 235. The second toothed element 240 is operatively coupled to the drive unit 234. More specifically, the second toothed element 240 is operatively coupled to the drive unit via the rotatable drive shaft 232. The second toothed structure 242 is disposed on the radial surface of the second toothed element 240 (i.e., the surface pointing radially relative to the axis of rotation of the rotatable drive shaft 232). The length of the second toothed element 240 in the radial direction relative to the axis of rotation of the rotatable drive shaft 232 can be configured to place the actuation system 230 closer to or further away from the elongated support pin 120'. In other words, by providing the second toothed element 240, the distance between the actuation system 230 and the elongated support pin 120' and / or the housing portion 220 can be adjusted. This allows for flexible placement of the actuation system 230 by appropriately configuring the second toothed element 240. Furthermore, it provides the possibility of using different actuation systems 230 (e.g., actuation systems 230 of different sizes).

[0053] Generally speaking, various combinations of the first toothed structure 142 and / or the first toothed element 140 with the second toothed structure 242 and / or the second toothed element 240 are possible. For example, according to Figure 9A The first tooth structure 142 of the embodiment can be used with... Figure 10A , Figure 10B , Figure 10C ,or Figure 10D The second tooth structure 242 is combined in any of the embodiments depicted herein. Figure 10D The embodiment thus represents a variation in which the second toothed element 240 is configured as a rack. In this case, the actuation system 230 does not include a rotatable drive shaft 232. Instead, the rack is directly coupled to the drive unit 234, and the drive unit is configured as a translation drive unit 234.

[0054] Similar to the first tooth structure 142, the second tooth structure may extend only along the arc length 244a of the sector 244 (see...). Figure 10CThe sector 244 is defined by a central angle θ2, preferably between 10° and 60°. Alternatively, the central angle θ2 can be a value between 5° and 360°, and particularly between 15° and 45°. Thus, in some embodiments, the second toothed structure 242 can alternatively extend along the entire circumference of either the rotatable drive shaft 232 (if the second toothed structure 242 is directly disposed on the rotatable drive shaft 232 and configured as an external tooth) or the second toothed element 240. The second toothed element 240 can be substantially shaped as a sector 244, or can consist substantially only of a sector 244 (see [link to relevant documentation]). Figure 10C Alternatively, the second toothed element 240 can be formed as a circle (not depicted). By adjusting the central angle θ1 to less than 360°, a full rotation is not required. Furthermore, manufacturing costs can be reduced because a smaller area is required in the toothed configuration.

As described above, the compressor 300 includes an adjustment assembly 30, which includes an adjustment mechanism 10 having a housing portion 220. Furthermore, the compressor 300 includes a compressor housing 310. The adjustment assembly 30 is inserted into the compressor housing 310 (see [link to image]). Figure 8 Therefore, housing portion 220 forms part of compressor housing 310. More specifically, housing portion 220 forms compressor inlet 312. In other words, housing portion 220 serves as the inlet port of compressor 300. Housing portion 220 is attached to compressor housing 310 via its flange portion 228. Although in Figure 6 , Figure 7 ,and Figure 8 Impeller 320 is not depicted; casing portion 220 is arranged upstream of impeller 320 (see, for example, Figure 1 ). Figure 7 The arrangement of orifice elements 100, 100' and drive ring 210 within the compressor housing 310 is shown in detail. It can be clearly seen that the elongated support pin 120' extends through housing portion 222 to engage with the actuation system 230 (i.e., the drive unit 234 outside the compressor housing 310). Herein lies... Figure 7 In the middle, the elongated support pin 120' is directly connected to the actuation system 230. Figure 8 Another exemplary configuration is shown, in which the elongated support pin 120' is connected to the actuation system 230 via a first toothed element 140 and a second toothed element 240.
