Abstract
Description
Technical Field
[0001] The art generally relates to systems and methods for internal seals of compressors, and more specifically, to seals for use within scroll assemblies in compressors. Background Technology
[0002] A scroll compressor uses a scroll assembly to compress refrigerant. This scroll assembly includes a stationary scroll member and a moving scroll member, which cooperate to form a sealing 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 sealing cavity to compress the refrigerant therein.
[0003] In scroll compressors with floating scrolls, axial balancing is typically achieved through dual pressure balancing, which facilitates precise adjustment of the clamping force to minimize frictional losses within the scroll. Floating track designs with dual pressure balancing require at least two seals to separate the suction pressure gas, intermediate pressure gas, and discharge pressure gas. However, challenges exist between the seals and the coupling, as they are often located in the same position.

[0050] In all the accompanying drawings, the corresponding reference numerals indicate the corresponding parts. Detailed Implementation
[0051] Reference Figure 1 and Figure 2 The compressor is generally designated as 100, and in this example, it is a scroll compressor. The compressor 100 (e.g., a high-side compressor) 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 108 of the outer casing 104, and a base 110 positioned at the opposite second end 112 of the outer casing 104. The scroll compressor 100 can be a floating track design, a floating non-track design such as co-rotation, and related compressor designs.
[0052] Now refer to Figures 3 to 30The compressor 100 includes a stationary scroll 120 and a moving scroll 122 operably engaged with a motor assembly 124. An end cap 106 and the stationary scroll 120 at least partially define a first chamber 128. In some embodiments, at least a portion of a housing 104 and / or a muffler plate (not shown) at least partially defines the first chamber 128. The housing 104 at least partially defines a second chamber 130. The motor assembly 124 includes a motor stator 134 and a rotor 136. The compressor 100 also includes a drive shaft 138 press-fitted within the rotor 136. The rotor 136 transmits rotational power to the drive shaft 138. The motor assembly 124 may be a variable-speed motor for rotating the drive shaft 138 at any of a variety of speeds. In the illustrated embodiment, the motor assembly 124 is positioned within the housing 104, for example, within the second chamber 130. In some other embodiments, the compressor 100 may be an open-drive compressor driven by a motor assembly positioned outside the compressor housing 102. The compressor 100 also includes a first bearing assembly 140 and a second bearing assembly 142 that rotatably support the drive shaft 138.
[0053] The drive shaft body 160 includes a longitudinal axis A1. The axial direction includes a direction aligned with and / or parallel to the longitudinal axis A1. The radial direction includes a direction radially relative to and perpendicular to the longitudinal axis A1. The drive shaft 138 includes the drive shaft body 160 and an eccentric body 162 offset from the drive shaft body 160. Both the drive shaft body 160 and the eccentric body 162 are cylindrical in shape. The eccentric body 162 includes a longitudinal axis A2 offset relative to the longitudinal axis A1. See also... Figure 9 , Figure 16 , Figure 23 and Figure 30 The drive shaft body 160 includes a first end portion 206 and a second end portion 208, which are rotatably supported by a first bearing assembly 140 and a second bearing assembly 142, respectively. An eccentric body 162 may extend from the first end portion 206.
[0054] The moving scroll member 122 may include an end plate 144 having a helical scroll 146 extending from a first side 148. The moving scroll member 122 may also include a cylindrical hub 154 projecting downward from the end plate 144 along a second side 152 of the main bearing housing 180, defining an annular flat surface 150. The annular flat surface 150 may engage with a first bearing assembly 140, as described below. An eccentric body 162 of the drive shaft 138 may be drivably engaged with a drive bearing 164. The drive bearing 164 transmits rotational motion from the eccentric body 162 to the moving scroll member 122. The drive bearing 164 may be positioned within the cylindrical hub 154 of the moving scroll member 122. Connectors (discussed below), such as cross-slider connectors, can engage with the moving scroll member 122 and the stationary scroll member 120 or the main bearing housing 180 to prevent relative rotation between the moving scroll member 122 and the stationary scroll member 120 or the main bearing housing 180. At least a portion of the main bearing housing 180 can partially define the boundary between chamber 128 and chamber 130.
[0055] The stationary scroll 120 may include an end plate 170 and a helical scroll 172 projecting downward from the end plate 170. The helical scroll 172 may engage with the helical scroll 146 of the moving scroll 122, for example, by means of meshing engagement between the scrolls, thereby creating a series of moving fluid cavities. Throughout the compression cycle, the fluid cavities defined by the helical scrolls 146, 172 may decrease in volume as the fluid cavities move from a radially outer position (e.g., at suction pressure) to a radially inner position (e.g., at discharge pressure above suction pressure). The end plate 170 may include a discharge passage 156 communicating with at least one of the fluid cavities in the radially inner position and allowing compressed working fluid, such as refrigerant or a mixture of refrigerant and lubricant (at or near discharge pressure), to flow through the discharge passage 156 and into the chamber 128.
[0056] Inlet 175 is attached to compressor housing 102 in end cap 106 for drawing working fluid into a fluid recess defined by spiral scrolls 172 and 146, where the working fluid is compressed. After compression, the compressed working fluid exits the fluid recess defined by spiral scrolls 172 and 146 through discharge passage 156 and enters chamber 128. The compressed working fluid flows from chamber 128 into chamber 130 through one or more passages between the stationary scroll 120 and the moving scroll 122 and housing 104. The compressed working fluid exits chamber 130 through discharge fitting 176. Discharge fitting 176 may be attached to base 110 of compressor housing 102. A discharge valve assembly (not shown) may be positioned within discharge fitting 176 and substantially prevents backflow through discharge fitting 176. Sealing terminal 178 may be attached to compressor housing 102 at base 110.
[0057] The compressor 100 includes a main bearing housing 180 that can be fixed relative to the compressor housing 102. For example, the main bearing housing 180 can be inserted (e.g., pressed) into the outer casing 104 of the compressor housing 102. A stationary scroll member 120 can be connected to the main bearing housing 180. The main bearing housing 180 includes a cylindrical hub 182 defining a cavity 184, the cavity 184 being sized and shaped to receive a first bearing assembly 140 within the cavity 184. The main bearing housing 180 and the first bearing assembly 140 can cooperate to support a drive shaft 138 for rotational movement relative to the main bearing housing 180 and the first bearing assembly 140. In an alternative embodiment, the main bearing housing 180 can axially support a movable scroll member 122 for orthorhombic movement relative to the main bearing housing 180.
[0058] The first bearing assembly 140 is a ball bearing, comprising an outer ring 190, an inner ring 192, and a plurality of balls 200 positioned between the outer ring 190 and the inner ring 192. In other embodiments, the first bearing assembly 140 may include other types of rolling bearings and / or sleeve / journal bearings. The inner ring 192 includes an inner surface (not shown) defining a bearing opening (not shown). A drive shaft body 160 is positioned within the bearing opening.
[0059] The drive shaft body 160 may have a first counterweight 220 and a second counterweight 222 attached between the first bearing assembly 140 and the second bearing assembly 142 to balance the rotation of the drive shaft 138. The first counterweight 220 and the second counterweight 222 may be configured and positioned such that the inertial force of the first counterweight 220 can cancel or balance the sum of the inertial forces of the second counterweight 222, the moving scroll member 122, the drive bearing 164, and the eccentric body 162. In other embodiments, alternative movable eccentric components may be used to replace the first counterweight 220, the second counterweight 222, or both, or additionally provided. In some cases, various seals and retaining rings may be balanced.
[0060] An exemplary compressor 100 includes a coupling, such as a cross-slider coupling, positioned between a moving scroll member 122 and a stationary component (e.g., a fixed scroll member 120, a main bearing housing 180). The cross-slider coupling 302 (or 402, 502, 602, 702, 802; hereinafter referred to as 302 for ease of reference) is configured to prevent relative rotation between the moving scroll member 122 and the fixed scroll member or the main bearing housing 180. The cross-slider coupling 302 may be directly or indirectly constrained between the moving scroll member 122 and the stationary component. In some cases, the cross-slider coupling 302 may be movably coupled (e.g., keyed) to the moving scroll member 122 and / or the stationary component, such that the cross-slider coupling 302 can move relative to the moving scroll member 122 and / or the stationary component in a first direction (e.g., upward) and a second direction (e.g., downward). The cross-slider coupling 302 may also move radially relative to the moving scroll member 122 and / or the main bearing housing 180. In some cases, the cross-slider coupling 302 can be movably coupled (e.g., keyed) to the moving scroll member 122 and / or the stationary member, such that the cross-slider coupling 302 can move relative to the moving scroll member 122 and / or the stationary member in a first direction (e.g., upward) and a second direction (e.g., downward) and radially relative to the moving scroll member 122 and / or the main bearing housing 180. In some cases, the coupling 302 can be at least partially balanced by one or more alternative moving eccentric members. The coupling 302 is positioned to seal one or more pressure chambers associated with the moving scroll member 122 and the stationary member. Details and arrangement of example seals are discussed in more detail below with respect to various embodiments and drawings.
[0061] As described below and shown in the figures, the cross-slider coupling 302, the moving scroll member 122, and the main bearing housing 180 may include various sealing configurations. In non-limiting examples, these various sealing configurations typically define pressure chambers, create compact compressor systems, and provide flexibility in generating and optimizing axial balancing schemes and combinations thereof. Therefore, similar components / features will be numbered the same in various embodiments. Unless explicitly stated or indicated by the context, the discussion of features of one embodiment may apply to other embodiments.
[0062] The end plate 144 of the moving scroll member 122, the main bearing housing 180, and the connecting member 302 together at least partially define the intermediate pressure chamber 196, as shown in the attached figures, for example... Figure 4 , Figure 11 , Figure 18 and Figure 25 As shown in the illustration. However, in other embodiments, the end plate 144 of the moving scroll member 122, the main bearing housing 180, and the connecting member 302 may at least partially define the external pressure chamber 194. In some embodiments, the end plate 144 of the moving scroll member 122, the main bearing housing 180, and the connecting member 302 may at least partially define the external pressure chamber 194 and the intermediate pressure chamber 196. Referring to embodiments 1 to 6, the intermediate pressure chamber 196 and / or the external pressure chamber 194 are in fluid communication with at least one of a series of moving fluid recesses formed by the helical scroll 146 of the moving scroll member 122 and the helical scroll 172 of the stationary scroll member 120. The end plate 144 of the moving scroll member 122 defines a port 198 that is in fluid communication between the series of moving fluid recesses and the intermediate pressure chamber 196, the series of moving fluid recesses and the external pressure chamber 194, or the series of moving fluid recesses and both the intermediate pressure chamber 196 and the external pressure chamber 194. Depending on the design of the compressor 100 (e.g., the location of port 198) and / or based on providing optimized axial balance (e.g., gas clamping force), pressure chambers 194, 196 can be at discharge pressure (e.g., high-pressure side), at intermediate pressure, and / or at suction pressure (e.g., low-pressure side). In some cases, at least two ports 198 can be in fluid communication with pressure chambers 194, 196.
[0063] One or more seals may be mounted relative to and / or adjacent to coupling 302. One or more seals may be configured to seal intermediate pressure chamber 196, external pressure chamber 194, or both. For example, adding one or more seals mounted relative to and / or adjacent to coupling 302 can seal pressure chambers created by the flow of gas at discharge pressure in cavities surrounding coupling 302. The combination of one or more seals and coupling 302 can be used to minimize the diameter of the compression mechanism and optimize the gas clamping force. The diameter of the compression mechanism may be predetermined and may at least partially define the size of the compressor 100 and the gas clamping force.
[0064] Seals (e.g., at least two seals) are suitably mounted on or adjacent to the coupling 302. The location of the seals can be selected from, but is not limited to, the end plate 144 of the moving scroll member 122, the cylindrical hub 154 of the moving scroll member 122, the coupling 302, the main bearing housing 180, and combinations thereof. The seals can define a circular, quadrilateral, elliptical, triangular, or triangular cross-section, or a combination thereof. One or more seals may include a double seal, for example, two or more seals at a sealing location. Double seals can define seals having the same or different cross-sectional shapes.
[0065] In the first embodiment, refer to Figures 3 to 9 The compressor 100 includes a cross-slider connector 302 at least partially positioned between a moving scroll member 122 and a main bearing housing 180. The connector 302 defines a top surface 304, a bottom surface 306, and a longitudinal axis A3 extending between the top and bottom surfaces 304. The top surface 304 of the connector 302 is positioned at least adjacent to the end plate 144 of the moving scroll member 122, and the bottom surface 306 of the connector 302 is positioned at least adjacent to the main bearing housing 180. The top surface 304 of the connector 302 is positioned to at least partially contact the end plate 144 of the moving scroll member 122 directly or indirectly, and the bottom surface 306 of the connector 302 is positioned to at least partially contact the main bearing housing 180 directly or indirectly.
[0066] The compressor 100 includes a first seal 308 mounted relative to an end plate 144 of the moving scroll member 122. The first seal 308 is mounted relative to the end plate 144 and positioned to extend along the direction of the coupling member 302. The first seal 308 is mounted relative to the end plate 144 such that the first seal 308 is in direct or indirect contact with the coupling member 302. The first seal 308 may be positioned within a channel 308' such that the surface of the seal is configured to contact the top surface 304 of the coupling member 302. The depth of the channel 308' may depend in part on the thickness of the first seal 308. The amount by which the first seal 308 protrudes from the end plate 144 along the direction of the coupling member 302 may depend in part on at least one of the following: the thickness of the first seal 308, the clearance between the coupling member 302 and the end plate 144, the depth of the channel 308', and combinations thereof. The channel 308' may extend axially relative to the longitudinal axis A3 of the coupling member 302.
[0067] The compressor 100 includes a second seal 310 mounted relative to a coupling 302. The second seal 310 is mounted relative to a bottom surface 306 of the coupling 302. The second seal 310 is mounted relative to the bottom surface 306 of the coupling 302 such that the second seal 310 directly or indirectly contacts the main bearing housing 180. The second seal 310 may be positioned within a channel 310' such that the surface of the seal is configured to contact the main bearing housing 180. The depth of the channel 310' may depend in part on the thickness of the second seal 310. The amount by which the second seal 310 protrudes from the coupling 302 along the direction of the main bearing housing 180 may depend in part on at least one of the following: the thickness of the second seal 310, the clearance between the coupling 302 and the main bearing housing 180, the depth of the channel 310', and combinations thereof. The channel 310' may extend axially relative to the longitudinal axis A3 of the coupling 302.
[0068] Reference Figures 5 to 7The top surface 304 of the connector 302 is generally planar and does not include a channel. The bottom surface 306 of the connector 302 is positioned opposite to the top surface 304 and includes a channel 310' configured to receive at least a portion of the second seal 310. The connector 302 includes a top protrusion 312 and a bottom protrusion 314 configured to engage directly or indirectly with the moving scroll member 122 and / or the main bearing housing 180. As depicted, the connector 302 includes two top protrusions 312 and two bottom protrusions 314. The top protrusions 312 extend outward from the top surface 304 of the connector 302 in a direction opposite to that of the bottom surface 306. The top protrusions 312 are configured to engage movably with the protrusion channel 316 of the moving scroll member 122. The bottom protrusion 314 extends outward from the bottom surface 306 of the connector 302 in the opposite direction to the top surface 304. The bottom protrusion 314 is positioned and shaped to engage movably with the protrusion channel (not shown) of the main bearing housing 180. The top protrusion 312 and the bottom protrusion 314 may extend vertically from the top surface 304 and the bottom surface 306, respectively.
[0069] Reference Figure 3 and Figure 4 The top protrusion 312 of the connecting member 302 is positioned within the protrusion channel 316 of the moving scroll member 122, such that the top protrusion 312 is configured to translate relative to the protrusion channel 316 of the moving scroll member 122. Similarly, the bottom protrusion 314 of the connecting member 302 is positioned within the protrusion channel (not shown) of the main bearing housing 180, such that the bottom protrusion 314 is configured to translate relative to the protrusion channel (not shown) of the main bearing housing 180. Figures 5 to 7As depicted, top protrusions 312 extend relatively spaced from top surface 304, and bottom protrusions 314 extend relatively spaced from bottom surface 306. The top protrusions 312 may be spaced apart from each other by approximately 180 degrees, and the bottom protrusions 314 may be spaced apart from each other by approximately 180 degrees. Therefore, one of the top protrusions 312 or the bottom protrusions 314 may be circumferentially spaced about every 90 degrees about the longitudinal axis A3 of the connector 302. However, it should be understood that more or fewer protrusions 312, 314 may be used without departing from the spirit / scope of this disclosure, and the protrusions 312, 314 may be spaced differently. In operation, the connector 302 may translate relative to the moving scroll member 122 and the main bearing housing 180 to ensure that the moving scroll member 122 and the main bearing housing 180 remain indirectly connected during movement. The movement of the moving scroll member 122 is translational, although the moving scroll member 122 moves in two directions. For example, with the Z-axis parallel to A1, the moving scroll member 122 moves along the X and Y axes. The top protrusion 312 of the connecting member 302 translates within the protrusion channel 316 of the moving scroll member 122, enabling the connecting member 302 to move along the X and Y axes. The bottom protrusion 314 of the connecting member 302 translates within the protrusion channel (not shown) of the main bearing housing 180, enabling the connecting member 302 to move along the X and Y axes.
[0070] As will be discussed below Figures 31 to 38 In more detail, seals 308 and 310 can be axially aligned and circumferentially aligned with each other, such that the outer portion of each seal 308 or 310 is aligned with the outer portion of the other seal 310 or 308. In other cases, seals 308 and 310 can be axially aligned but not circumferentially aligned. In yet another example, seals 308 and 310 may not be axially aligned. Seals 308 and 310 can be axially aligned relative to the longitudinal axis A3.

The hub seal 318 is mounted relative to the second side 152 of the main bearing housing 180 such that the hub seal 318 contacts the cylindrical hub 154 of the moving scroll member 122 directly or indirectly. The hub seal 318 may be positioned within a channel 318' such that the surface of the hub seal 318 is configured to contact an annular flat surface 150 of the cylindrical hub 154. The depth of the channel 318' may depend in part on the thickness of the hub seal 318. The amount by which the hub seal 318 protrudes from the main bearing housing 180 along the direction of the cylindrical hub 154 may depend in part on at least one of the following: the thickness of the hub seal 318, the clearance between the cylindrical hub 182 and the main bearing housing 180, the depth of the channel 318', and combinations thereof. Alternatively, the hub seal 318 may be positioned within the channel 318' and extend outward from the annular flat surface 150 of the cylindrical hub 154 along the direction of the second side 152 of the main bearing housing 180.
[0072] During operation, pressure generated by a series of moving fluid recesses formed by the helical scroll 146 of the moving scroll 122 and the helical scroll 172 of the stationary scroll 120 is released into port 198. Port 198 is in fluid communication with intermediate pressure chamber 196, external pressure chamber 194, or both. In some cases, a second port (not shown) may be in fluid communication with external chamber 194. The pressure within intermediate pressure chamber 196 may differ from the pressure within external pressure chamber 194. Each chamber 194, 196 is sealed with two or more seals positioned to directly or indirectly contact the main bearing housing 180, the moving scroll 122, and / or the coupling 302. For example, compressed gas discharged into external pressure chamber 194 may be sealed with a first seal 308 and a second seal 310. Furthermore, the gas discharged into the external pressure chamber 194 can be sealed using the first seal 308 and the second seal 310, and also sealed on the thrust surface (not shown) between the moving scroll member 122 and the stationary scroll member 120. The gas discharged into the intermediate pressure chamber 196 can be sealed using the first seal 308, the second seal 310, and the hub seal 318. The sealing of the pressure chambers 194 and 196 at least prevents pressure loss, which provides pressure to offset the scrolls against each other, thereby reducing efficiency losses due to leakage between the scrolls and minimizing frictional losses in the compression mechanism.

[0093] Reference Figure 24 and Figure 25 The top protrusion 612 of the connector 602 is positioned within the protrusion channel 616 of the moving scroll member 122, such that the top protrusion 612 is configured to translate relative to the protrusion channel 616 of the moving scroll member 122. Similarly, the bottom protrusion 614 of the connector 602 is positioned within the protrusion channel (not shown) of the main bearing housing 180, such that the bottom protrusion 614 is configured to translate relative to the protrusion channel (not shown) of the main bearing housing 180. Figures 26 to 28As depicted, top protrusions 612 extend relatively spaced from top surface 604, and bottom protrusions 614 extend relatively spaced from bottom surface 606. The top protrusions 612 may be spaced apart from each other by approximately 180 degrees, and the bottom protrusions 614 may be spaced apart from each other by approximately 180 degrees. Therefore, one of the top protrusions 612 or the bottom protrusions 614 may be circumferentially spaced about every 90 degrees about the longitudinal axis A3 of the connector 602. However, it should be understood that more or fewer protrusions 612, 614 may be used, and the protrusions 612, 614 may be spaced differently, without departing from the spirit / scope of this disclosure. In operation, the connector 602 may translate relative to the moving scroll member 122 and the main bearing housing 180 to ensure that the moving scroll member 122 and the main bearing housing 180 remain indirectly connected during movement. The movement of the moving scroll member 122 is translational, although the moving scroll member 122 moves in two directions. For example, with the Z-axis parallel to A1, the moving scroll member 122 moves along the X and Y axes. The top protrusion 612 of the connecting member 602 translates within the protrusion channel 616 of the moving scroll member 122, enabling the connecting member 602 to move along the X and Y axes. The bottom protrusion 614 of the connecting member 602 translates within the protrusion channel (not shown) of the main bearing housing 180, enabling the connecting member 602 to move along the X and Y axes.
[0094] As will be discussed below Figures 31 to 38 In more detail, seals 608 and 610 can be axially aligned and circumferentially aligned with each other, such that the outer portion of each seal 608 or 610 is aligned with the outer portion of the other seal 610 or 608. In other cases, seals 608 and 610 can be axially aligned but not circumferentially aligned. In yet another example, seals 608 and 610 may not be axially aligned. In yet another example, seals 608 and 610 can be axially aligned relative to the longitudinal axis A3.
[0095] The compressor 100 may further include a hub seal 618 positioned to contact the cylindrical hub 154 of the moving scroll member 122. The hub seal 618 is mounted relative to a second side 152 of the main bearing housing 180. The hub seal 618 is mounted relative to the second side 152 of the main bearing housing 180 such that the hub seal 618 contacts the cylindrical hub 154 of the moving scroll member 122 directly or indirectly. The hub seal 618 may be positioned within a channel 618' such that the surface of the seal 618 is configured to contact an annular flat surface 150 of the cylindrical hub 154. The depth of the channel 618' may depend in part on the thickness of the hub seal 618. The amount by which the hub seal 618 protrudes from the main bearing housing 180 along the direction of the cylindrical hub 154 may depend in part on at least one of the following: the thickness of the hub seal 618, the clearance between the cylindrical hub 182 and the main bearing housing 180, the depth of the channel 618', and combinations thereof. Alternatively, the hub seal 618 may be positioned within the channel 618' and extend outward from the annular flat surface 150 of the cylindrical hub 154 along the direction of the second side 152 of the main bearing housing 180.
[0096] During operation, pressure generated by a series of moving fluid recesses formed by the helical scrolls 146, 172 of the moving scroll 122 and the stationary scroll 120 is released into port 198. Port 198 is in fluid communication with intermediate pressure chamber 196, external pressure chamber 194, or both. In some cases, a second port (not shown) may be in fluid communication with external chamber 194. The pressure within intermediate pressure chamber 196 may differ from the pressure within external pressure chamber 194. Each chamber 194, 196 is sealed with two or more seals positioned to directly or indirectly contact the main bearing housing 180, the moving scroll 122, and / or the coupling 602. For example, compressed gas discharged into external pressure chamber 194 may be sealed with a first seal 608 and a second seal 610. Gas discharged into intermediate pressure chamber 196 may be sealed with a first seal 608, a second seal 610, and a hub seal 618. The seals of pressure chambers 194 and 196 at least prevent pressure loss, which provides pressure to offset the vortices against each other, thereby reducing efficiency loss due to leakage between the vortex rolls and minimizing frictional losses in the compression mechanism.
[0097] Reference Figure 39 and Figure 40The compressor, in this example a scroll compressor, is generally designated 1000.

[0098] Compressor 1000 includes the features / components previously described with respect to compressor 100. Therefore, in various embodiments, similar components / features will be numbered the same. Unless explicitly stated otherwise, features described with respect to one embodiment may be applicable to other embodiments. For example, detail 1 of scroll compressor 1000 is similar to detail 1 of scroll compressor 100, as... Figure 4 , Figure 11 , Figure 18 and Figure 25 As described herein, the muffler plate 1014 is also removed. Therefore, the cross-slider coupling 302 of the compressor 1000 can include any sealing configuration as described herein. The compressor 1000 also includes a passage 1016 for the fixed scroll member 120 for conveying a gas flow from chamber 130 to chamber 128 (e.g., see...). Figure 41 ).
[0099] In yet another implementation, such as Figures 31 to 33 As depicted, the coupling 702 defines a top surface 704, a bottom surface 706, and a longitudinal axis A3 extending between the top surface 704 and the bottom surface 706. The coupling 702 can be positioned within the compressor 100, as throughout this disclosure (e.g., Figures 10 to 16As described in embodiment 2), the connector 702 includes a first channel 708' positioned on a top surface 704 and a second channel 710' positioned on a bottom surface 706. The first channel 708' is configured to at least partially receive a first seal (not shown), and the second channel 710' is configured to at least partially receive a second seal (not shown). The channels 708', 710' can be axially positioned relative to the longitudinal axis A3 of the connector 702. Furthermore, the channels 708', 710' are axially aligned and circumferentially aligned with each other, such that the outer portion of each channel 708', 710' is aligned with the outer portion of the other channel 710', 708'. As depicted, the channels 708', 710' are elliptical in shape. However, it should be understood that in other embodiments, one of the channels may be circular in shape, while the other channel may be elliptical in shape.
[0100] The connector 702 includes a top protrusion 712 and a bottom protrusion 714, which are configured to engage directly or indirectly with the moving scroll member 122 and / or the main bearing housing 180. As depicted, the connector 702 includes at least two top protrusions 712 and at least two bottom protrusions 714. The top protrusions 712 extend outward from the top surface 704 of the connector 702 in a direction opposite to the bottom surface 706. The top protrusions 712 are configured to movably engage with the protrusion channel of the moving scroll member 122. The bottom protrusions 714 extend outward from the bottom surface 706 of the connector 702 in a direction opposite to the top surface 704. The bottom protrusions 714 are configured to movably engage with the protrusion channel (not shown) of the main bearing housing 180. The top protrusions 712 and the bottom protrusions 714 may extend vertically from the top surface 704 and the bottom surface 706, respectively.
[0101] As depicted, top protrusions 712 extend relatively spaced from top surface 704, and bottom protrusions 714 extend relatively spaced from bottom surface 706. The top protrusions 712 may be spaced apart from each other by approximately 180 degrees, and the bottom protrusions 714 may be spaced apart from each other by approximately 180 degrees. Therefore, one of the top protrusions 712 or the bottom protrusions 714 may be radially spaced about every 90 degrees about the longitudinal axis A3 of the connector 702. However, it should be understood that more or fewer protrusions 712, 714 may be used, and the protrusions 712, 714 may be spaced differently, without departing from the spirit / scope of this disclosure. In operation, the connector 702 may translate relative to the moving scroll member 122 and the main bearing housing 180 to ensure that the moving scroll member 122 and the main bearing housing 180 remain indirectly connected during rotation.
[0102] In yet another implementation, such as Figures 34 to 36 As depicted, the connector 802 defines a top surface 804, a bottom surface 806, and a longitudinal axis A3 extending between the top surface 804 and the bottom surface 806. The connector 802 can be positioned within the compressor 100, 1000, as throughout this disclosure (e.g., Figures 10 to 16 As described in embodiment 2), the connector 802 includes a first channel 808' positioned on a top surface 804 and a second channel 810' positioned on a bottom surface 806. The first channel 808' is configured to at least partially receive a first seal (not shown), and the second channel 810' is configured to at least partially receive a second seal (not shown). The channels 808', 810' can be axially positioned relative to the longitudinal axis A3 of the connector 802. The channels 808', 810' are axially aligned but not circumferentially aligned with each other, such that the outer portion of each channel 808', 810' is not aligned with the outer portion of the other channel 810', 808'. As depicted, the channels 808', 810' are elliptical in shape, and in a non-limiting example, each channel 808', 810' is radially rotated by approximately 90 degrees, such that the wider portion of the first channel 808' is positioned opposite to the narrower portion of the second channel 810'. However, it should be understood that channels 808' and 810' can be radially rotated to any desired degree in order to provide optimal gas clamping force. In some embodiments, one of the channels may be circular in shape, while the other channel may be elliptical in shape.
[0103] The connector 802 includes a top protrusion 812 and a bottom protrusion 814, which are configured to engage directly or indirectly with the moving scroll member 122 and / or the main bearing housing 180. As depicted, the connector 802 includes at least two top protrusions 812 and at least two bottom protrusions 814. The top protrusions 812 extend outward from the top surface 804 of the connector 802 in a direction opposite to the bottom surface 806. The top protrusions 812 are configured to movably engage with a protrusion channel of the moving scroll member 122. The bottom protrusions 814 extend outward from the bottom surface 806 of the connector 802 in a direction opposite to the top surface 804. The bottom protrusions 814 are configured to movably engage with a protrusion channel (not shown) of the main bearing housing 180. The top protrusions 812 and the bottom protrusions 814 may extend vertically from the top surface 804 and the bottom surface 806, respectively.
[0104] As depicted, top protrusions 812 extend relatively spaced from top surface 804, and bottom protrusions 814 extend relatively spaced from bottom surface 806. The top protrusions 812 may be spaced apart from each other by approximately 180 degrees, and the bottom protrusions 814 may be spaced apart from each other by approximately 180 degrees. Therefore, one of the top protrusions 812 or the bottom protrusions 814 may be radially spaced about every 90 degrees about the longitudinal axis A3 of the connector 802. However, it should be understood that more or fewer protrusions 812, 814 may be used, and the protrusions 812, 814 may be spaced differently, without departing from the spirit / scope of this disclosure. In operation, the connector 802 may translate relative to the moving scroll member 122 and the main bearing housing 180 to ensure that the moving scroll member 122 and the main bearing housing 180 remain indirectly connected during rotation.
[0105] One or more seals may have circular, elliptical, quadrilateral, triangular, or combinations thereof shapes and / or cross-sectional shapes. One or more seals may be centered relative to the center of the moving scroll member 122. By centering one or more seals, the frictional loss of the moving scroll member 122 can be minimized. (Refer to...) Figure 37 Seals 908 and 910 have a circular shape as defined by the circumference of seals 908 and 910. Seals 908 and 910 may be centered relative to the center of the moving scroll member 122. (Refer to...) Figure 38 Seals 908 and 910 have an elliptical shape defined by the circumference of seals 908 and 910. Seals 908 and 910 may be centered relative to the center of the moving scroll member 122. Figure 37 and Figure 38 As shown in the figure, seals 908 and 910 may be coaxial with respect to another seal 910 or 908, but the combined seals 908 and 910 may be centered with respect to the longitudinal axis A1 of the moving scroll 122.
[0106] Although the seals described herein are designated as “first” seals and “second” seals, they may be interchangeable without departing from the spirit / scope of this disclosure unless otherwise indicated or stated.
[0107] Compared to existing systems and methods, the implementations of the systems and methods disclosed herein achieve superior results. For example, combining the cross-slider connecting ring and the external seal can minimize the diameter of the compression mechanism and optimize the gas clamping force.
