[0001] This patent application claims priority to Indian application No. 202511010682, filed on February 8, 2025, the disclosure of which is incorporated herein by reference in its entirety as a part of this application. Technical Field

[0002] The field of this disclosure generally relates to scroll compressors, and more specifically to scroll compressors including a scroll element that defines a discharge passage having multiple outlets. Background Technology

[0003] A scroll compressor uses a stationary scroll member and a moving scroll member to compress a working fluid such as a refrigerant. The stationary and moving scroll members cooperate to form a sealed cavity between them. During operation of the scroll compressor, the movement of the moving scroll member relative to the stationary scroll member continuously changes the volume of the sealed cavity to compress the working fluid therein.

[0004] Conventionally, compressed working fluid exits the sealed cavity between the meshing scroll members through a discharge port regulated by a reed or check valve assembly. The reed valve assembly includes a flexible reed that flexes between an open and closed position. In the open position, the reed flexes away from the discharge port and does not impede the flow of compressed working fluid out of the discharge port; in the closed position, the reed covers the discharge port to block the flow of compressed working fluid out of the sealed cavity between the meshing scroll members. In some known compressors, a bridging insert may be positioned between the reed and the discharge port. The bridging insert spans the discharge port and supports the distal end of the reed, thereby reducing closing stress on the reed. However, the bridging insert requires additional manufacturing processes and increases assembly time, and can also reduce compressor efficiency by blocking part of the outlet area of ​​the discharge port.

[0049] Throughout the accompanying drawings, corresponding reference numerals indicate the corresponding components. Detailed Implementation

[0050] Reference Figure 1The sample compressor is generally indicated by 100. The compressor 100 includes a compressor housing 102, which forms at least one sealed cavity within which refrigerant compression is achieved. The compressor housing 102 includes an outer casing 104, an end cap 106 positioned at a first end 118 of the outer casing 104, and a base 108 positioned at the opposite second end 120 of the outer casing 104. In the illustrated example, the outer casing 104 is cylindrical, and the end cap 106 and base 108 are each generally dome-shaped, such that the compressor housing 102 has a generally elliptical profile. The outer casing 104, end cap 106, and / or base 108 can have different shapes depending on the desired shape and profile of the compressor housing 102. The end cap 106 and / or base 108 can be attached to the respective ends 118, 120 of the outer casing 104 in any suitable manner to connect the components. For example, end cap 106 and / or base 108 may be welded or bolted to housing 104.

[0051] Compressor 100 includes an inlet fitting 110 attached to compressor housing 102 at an inlet opening (not shown), through which working fluid (e.g., refrigerant) enters at least one sealed cavity formed by compressor housing 102. For example, the working fluid is drawn into compressor 100 via inlet fitting 110 and compressed in at least one sealed cavity. After compression, the compressed working fluid exits compressor 100 through discharge opening 112. Discharge fitting 114 may be attached to compressor housing 102 at discharge opening 112. In the example compressor 100, discharge opening 112 is located on base 108, and discharge fitting 114 is attached to base 108 at discharge opening 112, allowing compressed working fluid to exit a second chamber 117 defined by base 108. Figure 2 In the example compressor 100, the working fluid in the second chamber 117 is at discharge pressure, and the second chamber 117 can alternatively be referred to as the discharge chamber. A discharge valve assembly (not shown) may be provided within the discharge fitting 114 to prevent backflow. A sealed electrical terminal 115 may also be attached to the compressor housing 102, for example, to the housing 104.

[0052] Figure 2 This is a cross-sectional view of compressor 100. Compressor 100 includes a compressor housing 102, which includes an outer casing 104, an end cap 106 positioned at a first end 118 of the outer casing 104 and defining a first chamber 116, and a base 108 positioned at a second end 120 of the outer casing 104 and defining a second chamber 117. Compressor 100 also includes a motor assembly 122 and a compression mechanism (e.g., a scroll assembly) mounted in the compressor housing 102 and operatively connected to the motor assembly 122, the compression mechanism being generally indicated by 204.

[0053] Motor assembly 122 includes a motor stator 124 and a rotor 126. The rotor 126 can be press-fitted onto a drive shaft 128 positioned within the compressor housing 102 and can transmit rotational power to the drive shaft 128. Motor assembly 122 can be a variable-speed motor for rotating the drive shaft 128 at any of a plurality of speeds. In the illustrated embodiment, motor assembly 122 is disposed within housing 104. In some other embodiments, compressor 100 can be an open-drive compressor driven by motor assembly 122 disposed outside compressor housing 102.

[0054] The drive shaft 128 is rotatably supported within a first bearing housing assembly 206 and a second bearing housing assembly 130. The first bearing housing assembly 206 and the second bearing housing assembly 130 are axially displaced and located on opposite sides of the motor assembly 122. The first bearing housing assembly 206 is located near a first end 118 of the housing 104, and the second bearing housing assembly 130 is located near a second end 120 of the housing 104 (e.g., within the base 108). The drive shaft 128 extends through the first bearing housing assembly 206 and includes an eccentric body 132 extending axially beyond the first bearing housing assembly 206.

[0055] The first bearing housing assembly 206 includes a primary bearing 134, and the second bearing housing assembly 130 includes a secondary bearing 136. The primary bearing 134 and the secondary bearing 136 rotatably support the drive shaft 128 within their respective bearing housing assemblies 206 and 130. The first bearing housing assembly 206 includes the primary bearing 134 and the primary bearing housing 208. The primary bearing 134 and / or the secondary bearing 136 may be rolling element bearings having: an inner ring defining a bearing surface and a bearing opening for receiving the drive shaft 128; an outer ring radially spaced outward relative to the inner ring; and a plurality of spherical elements or rollers disposed between the inner and outer rings. Alternatively, in some embodiments, the primary bearing 134 and / or the secondary bearing 136 are journal bearings, and the drive shaft 128 is rotatably supported by the journal bearings 134 and / or 136 within the bearing opening and relative to a fixed inner bearing surface. The main bearing 134 and / or the secondary bearing 136 can be any suitable bearing type.

[0056] The compression mechanism 204 includes a moving scroll member 226 and a stationary scroll member 228. The moving scroll member 226 includes a generally disc-shaped moving plate 230 defining opposing radial surfaces. A moving helical scroll 232 extends axially from one of the surfaces of the moving plate 230, and the surface opposite to the moving helical scroll 232 includes a cylindrical hub 236 extending axially therefrom. A drive bushing 239 is disposed in the cylindrical hub 236 and receives an extension of the drive shaft 128 through an eccentric body 132 of the main bearing housing 208. The eccentric body 132 engages in a driven manner with the drive bushing 239 in the cylindrical hub 236 of the moving scroll member 226, and facilitates the transmission of rotational motion of the drive shaft 128 to circumferential motion of the moving scroll member 226 relative to the main bearing housing 208 and / or the stationary scroll member 228. Unmarked couplings (e.g., cross-slider couplings) may engage with the moving scroll member 226, the main bearing housing 208, and / or the stationary scroll member 228 to limit or prevent relative rotation between them.

[0057] The fixed scroll member 228 includes a fixed body 238 defining an upper surface 241 and an opposite lower surface 242. In some embodiments, the fixed scroll member 228 may include an annular wall 244. A fixed helical scroll 240 extends generally axially from the lower surface 242 and faces the moving helical scroll 232. The fixed scroll member 228 also includes a protrusion 246 extending axially from the upper surface 241 of the fixed body 238.

[0058] The fixed helical scroll 240 engages or meshes with the moving helical scroll 232 of the moving scroll member 226, thereby defining a series of fluid cavities. The circumferential motion of the moving scroll member 226 is converted into the motion of the fluid cavities defined by the helical scrolls 232 and 240, thereby reducing the volume of the fluid cavities to compress the working fluid within them. During the compression cycle of the compression mechanism 204, the volume of the fluid cavities defined by the helical scrolls 232 and 240 decreases as the circumferential motion of the moving scroll member 226 is converted into the motion of the fluid cavities from a radially outer position 250 (at suction pressure) to a radially intermediate position (at intermediate pressure) and then to a radially inner position 252 (at discharge pressure).

[0059] Figures 14 to 15 Another example compressor, generally designated 500, is depicted. This compressor includes a compression mechanism 204, which comprises a moving scroll member 226 and a fixed scroll member 228. Compressor 500 has the same characteristics as described above. Figures 2 to 13 The compressor 100 described includes one or more similar elements and features, including similar parts and features marked with the same annotation number.

[0060] Compressors 100 and 500 include a discharge assembly 300, which includes a scroll member 302 and a reed valve assembly 304. At least one of a stationary scroll member 228 or a moving scroll member 226 can be the scroll member 302. In the illustrated embodiment, the scroll member 302 is the stationary scroll member 228 described above. In an alternative embodiment, the scroll member 302 is the moving scroll member 226.

[0061] The scroll member 302 includes a discharge passage 310 defined by a discharge boundary 312, the discharge passage 310 being formed through the body 238 of the scroll member 302 for discharging compressed working fluid (e.g., refrigerant) compressed by the compression mechanism 204. Specifically, the discharge passage 310 communicates with a fluid recess located at a radially inward position 252 within a fluid recess defined by helical scrolls 232 and 240, and allows compressed working fluid at discharge pressure to flow into the first chamber 116.

[0062] The scroll member 302 may include one or more intermediate ports 260 extending through the body 238. Each intermediate port 260 is located radially outward of the discharge passage 310 and allows communication with a fluid recess located at a radially inward position 252 in a fluid recess defined by the helical scrolls 232 and 240. The flow of working fluid from the corresponding fluid recess into the first chamber 116 through the intermediate ports 260 can be regulated by a valve assembly 262 (e.g., a reed valve assembly) located on or connected to the upper surface 241 of the body 238. Figure 2 and Figure 13 As shown in the diagram. For example, valve assembly 262 may be positioned adjacent to intermediate port 260 to selectively allow or restrict the flow of working fluid into the first chamber 116. Additionally and / or alternatively, one or more intermediate ports 260 may be sensor ports for receiving sensors (e.g., temperature sensors or pressure sensors) to monitor operating parameters (e.g., temperature or pressure) within the corresponding fluid recess during operation of the compression mechanism 204.

[0063] The inlet fitting 110 can be positioned at one or more different locations on the compressor housing 102 according to the desired entry point of the working fluid within at least one sealed cavity formed by the compressor housing 102. For example, the inlet fitting 110 can be fluidly connected to an inlet port 264 formed through the scroll assembly 204, through which the working fluid is supplied to a cavity of the scroll assembly 204 located at or near the radially outer position 250. Figures 1 to 12 In the embodiment illustrated, the inlet port 264 is formed to pass through the upper surface 241 of the body 238 and is generally parallel to the longitudinal axis A. 100 Extend. In Figures 14 to 23 In the embodiment illustrated, the inlet port 264 is formed as an annular wall 244 passing through the vortex member 302 and extending substantially perpendicular to the longitudinal axis A100.

[0064] Reference Figures 9 to 12 The discharge passage 310 extends between an inlet 370 defined by an inlet boundary 372 formed on the lower surface 242 of the body 238 and an outlet 380 defined by an outlet boundary 382 formed on the upper surface 241 of the body 238. Compressed working fluid exits the space between the spiral scroll 232 and the spiral scroll 240 at a radially inward position 252, enters the discharge passage 310 through the inlet 370, and exits the discharge passage 310 through the outlet 380 and enters the chamber 116. In the illustrated embodiment, the discharge passage 310 includes four outlets 380. Figures 14 to 23 In the embodiment illustrated herein, the discharge passage 310 includes a pair of outlets 380, for example, two outlets 380. In the embodiment illustrated herein, the discharge passage 310 includes a single inlet 370.

[0065] Reference Figures 9 to 12 The discharge channel 310 includes a vortex discharge port 390 and two or more discharge connection ports 392. The discharge connection ports 392 extend from a first intermediate end 394 to an outlet 380, and the vortex discharge port 390 extends from an inlet 370 to a second intermediate end 396. The vortex discharge port 390 includes a vortex discharge port depth d extending between the inlet 370 and the second intermediate end 396. 390 The discharge connection port 392 includes a discharge connection port depth d extending between the first intermediate end 394 and the outlet 380. 392 . Figure 13 and Figure 24 In some implementations, the depth d of the discharge connection port is... 392 d of the vortex discharge port 390 Long. In some implementations, the depth d of the discharge connection port. 392 With the depth d of the vortex discharge port 390 Generally the same. In the illustrated embodiment, the discharge channel 310 includes four discharge connection ports 392. The outlet depth d of each of the plurality of discharge connection ports 392 is... 392 They can be at roughly the same depth. Figures 14 to 23 In the embodiment illustrated herein, the discharge channel 310 includes two outlets 380 and two discharge connection ports 392. In the embodiment illustrated herein, the discharge channel 310 includes a separate vortex discharge port 390.

[0066] In the illustrated embodiment, each of the discharge ports 392 has a tapered orifice end. Alternatively, one or more of the discharge ports 392 may have a flat orifice end. In the illustrated embodiment, each of the discharge ports 392 is circular in shape and has approximately the same diameter. In alternative embodiments, the discharge ports 392 and / or outlet 380 may have different dimensions, such as different diameters or shapes.

[0067] The body 238 also includes a bridging surface 400 formed between the outlets 380. Figures 1 to 12 In the embodiment illustrated, the bridging surface 400 is disposed between the four outlets 380 and is shaped to resemble a cross shape having a central portion and four radially extending portions positioned between adjacent outlets 380. The radially extending portions of the cross shape may include one or more concave portions shaped to complement the arched boundaries of the adjacent outlets 380.

[0068] Figure 13 , Figure 24 , Figure 27 and Figure 30 The illustration shows the discharge volume of the discharge passage 310 defined by the discharge boundary 312. In some embodiments, at least a portion of the discharge connection port 392 is not aligned with the corresponding vortex discharge port 390 in the axial and / or radial directions. For example, the width and / or diameter of the vortex discharge port 390 may be smaller than the width and / or diameter of the outer perimeter 408 surrounding the plurality of discharge connection ports 392.

[0069] exist Figures 14 to 23 In the embodiment illustrated, the bridging surface 400 spans between the two outlets 380. (Refer to...) Figures 25 to 30 The outlet 380 and the bridging surface 400 may have alternative shapes and / or sizes. For example, in some alternative embodiments, the outlet 380 is elliptical or bean-shaped, and the bridging surface 400 includes an annular portion. Figures 25 to 27 In some other alternative embodiments, the bridging portion is T-shaped, and the outlet 380 is wedge-shaped. Figures 28 to 30 .

[0070] A reed valve assembly 304, mounted to the upper surface 241 of the body 238, regulates the compressed working fluid exiting the discharge passage 310 through outlet 380. The reed valve assembly 304 includes a reed 410 and a backing 412, and can be mounted to the compressor 100 using any suitable fastener 414. When the reed valve assembly 304 is mounted to the upper surface 241, the reed 410 is disposed between the upper surface 241 and the backing 412. A portion of the reed 410 can bend between a closed position and an open position. When the reed 410 is in the closed position, the reed 410 substantially obstructs the discharge passage 310, for example, obstructing each outlet of the outlet 380, and the reed 410 may contact the upper surface 241 on or around the outer periphery 408 surrounding the outlet 380. When the reed 410 is in the open position, the reed 410 substantially does not obstruct the outlet 380 of the discharge passage 310. For example, when the reed 410 is in the open position, at least a portion of the reed 410 can flex away from the upper surface 341 toward the arched portion 420 of the backing 212.

[0071] Figures 32A to 32C as well as Figures 34A to 34C The illustration shows the position of outlet 380 relative to the outer boundary 422 of reed 410. Reed 410 is sized and shaped such that when reed 410 is positioned in the closed position, it covers all outlets of outlet 380 in the discharge channel 310. In the illustrated embodiment, reed 410 includes an outer boundary 422, and when reed 410 is positioned in the closed position, each of the four outlets 380 is contained within the boundary 422 and spaced apart from the periphery 480 by a gap distance C. d .exist Figures 32A to 32C In the illustrated embodiment, two of the outlets 380 have centers parallel to the longitudinal axis of the reed 410, and two of the outlets 380 have centers perpendicular to the longitudinal axis of the reed 410. In other embodiments, the plurality of outlets 380 may have different arrangements or patterns relative to the outer boundary 422 of the reed 410.

[0072] Figure 32B and Figure 34B The distribution of closing stress on the reed 410 is shown. The bridging surface 400 supports the distal end of the reed 410, reducing the unsupported length of the reed 410 and thus lowering the closing and opening stresses of the reed 410. Furthermore, the contact between the reed 410 and the bridging surface 400 prevents the reed 410 from deflecting into the discharge channel 310, thereby improving the seal between the reed 410 and the outlet 380 of the discharge channel 310.

[0073] Reference Figure 32C and Figure 34CIt shows the sealing profile between the reed 410 and the outlets 380 when the reed 410 is in the closed position and the reed 410 covers the multiple outlets 380, and the reed 410 contacts and seals with the bridging surface 400 and the outer periphery 408 surrounding the multiple outlets 380.

[0074] In some embodiments, the scroll member 302 includes a recessed region 430 defined by a recessed boundary 432 formed in the upper surface 241 of the scroll member 302. An outlet 380 is positioned within the recessed region 430 and surrounded by the recessed boundary 432. An outer boundary 422 of a reed 410 extends beyond the recessed boundary 432, such that at least a portion of the reed 410 can rest on the upper surface 241 of the scroll member 302 in the region surrounding the recessed region 430. The reed 410 may be flexible, such that at least a portion of the reed 410 can flex into the recessed region 430, and at least a portion of the reed 410 rests on and / or seals against the region surrounding the outlet 380 and the bridging surface 400, thereby ensuring a seal between the reed 410 and the region surrounding the recessed boundary 432 while the reed 410 is supported by the bridging surface 400.

[0075] Refer again Figure 8 and Figure 19 The inlet boundary 372 of the inlet 370 of the defined discharge passage 310 is sized and shaped to be located in a radially inward position adjacent to the spiral scroll 240. For example, the inlet boundary 372 defining the inlet 370 may be generally kidney-shaped, having an arched portion similar to the arched portion of the scroll 340, and a recessed portion shaped to complement the central end of the scroll 340.

[0076] Figure 33 It's about leaving. Figure 1 The diagram shows a perspective view of the compressed working fluid flow through the four outlets 380 of the discharge passage 310 of the compressor 100. The working fluid exits the four outlets 380 such that the working fluid flows radially outward at 360° from the scroll assembly 204. Figure 35 It's about leaving. Figure 14 The diagram shows a perspective view of the compressed working fluid flow at the two outlets 380 of the discharge passage 310 of the compressor 500. The working fluid exits the two outlets 380 such that the working fluid flows radially outward at 120° from the scroll assembly 204.

[0077] Figure 31 This is a diagram illustrating the actuated opening and closing stresses of the reed during operation, as well as fatigue acceptance criteria including an acceptable region. For the embodiment described herein, the scroll assembly including multiple outlets 380 is included within the acceptable region.

Figure 1 The compressor 100 shown has four outlets 380 of its discharge passage 310 and Figure 14 A table showing the parameters of the two outlets 380 of the discharge passage 310 of the compressor 500 is illustrated. One or more discharge parameters, such as mass flow rate, pressure, and refrigerant density, may be the same or substantially the same between a conventional HVE reed, an embodiment including two outlets 380, and an embodiment including four outlets 380. In some embodiments, the discharge passage may include multiple confinements. For example, when the reed is in the open position, the working fluid may flow around the reed, and subsequently, the working fluid may flow through the port. The confinements may be in series. The effective flow area is calculated at least in part based on the confinements located around the open valve. Figure 36 The paper also demonstrates the pressure difference and power loss based on the pressure difference passing through the open valve.

[0079] In the embodiments described herein, the scroll member defining the discharge channel includes a bridging portion that supports a portion of the reed, thereby reducing the closing stress on the reed and improving the sealing engagement between the reed and the boundary of the discharge channel outlet. In the embodiments described herein, the scroll member includes a bridging portion spanning between two or more outlets of the discharge channel. This bridging portion is integrally formed with the scroll member and requires no additional manufacturing process or assembly of additional components.

[0080] The embodiment of the scroll member described herein, including the bridging portion, reduces the unsupported span length of the reed while maintaining the flow area at the outlet. The embodiment of the scroll member described herein includes a recessed region surrounding the outlet of the discharge channel, the recessed region having a coverage area contained within the outer boundary of the reed, such that at least a portion of the reed flexes into the recessed region, improving the seal between the reed and the boundary of the recessed region.

[0081] As used herein, when used in conjunction with ranges of size, concentration, temperature or other physical or chemical properties or characteristics, the terms “about,” “basically,” “essentially,” and “approximately” are intended to cover variations that may exist within the upper and / or lower limits of the range of a property or characteristic, including variations caused, for example, by rounding, measurement methods, or other statistical changes.

[0082] When elements or embodiments of this disclosure are introduced, the articles “a,” “an,” “the,” and “the” are intended to indicate the presence of one or more elements. The terms “comprising,” “including,” “containing,” and “having” are intended to be inclusive and mean that additional elements may be present in addition to those listed. The use of terms indicating a particular orientation (e.g., “top,” “bottom,” “side,” etc.) is for ease of description and does not require any particular orientation of the described object.

[0083] Since various changes can be made to the above construction and methods without departing from the scope of this disclosure, it is intended that all content contained in the above description and shown in the accompanying drawings should be interpreted as illustrative and not as restrictive.
