Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings.

The exemplary embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those skilled in the art. Numerous specific details are set forth, such as examples of specific components, devices, and methods, in order to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to one skilled in the art that the example embodiments may be embodied in many different forms without the use of specific details, and should not be construed as limiting the scope of the disclosure. In some exemplary embodiments, well-known processes, well-known device structures, and well-known techniques have not been described in detail.

The terminology used herein is for the purpose of describing exemplary embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "includes," and "including" are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein should not be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It should also be understood that additional or alternative steps may be employed.

When an element or layer is referred to as being "on," "engaged to," "connected to" or "coupled to" another element or layer, it can be directly on, engaged to, connected to or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other terms (e.g., "between" and "directly between", "adjacent" and "directly adjacent" etc.) used to describe the relationship between elements should be interpreted in the same manner. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first," "second," and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as "inner," "outer," "below," "under," "above," "upper," and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the example term "under" may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Referring to fig. 1-6, a compressor 10 is provided, and the compressor 10 may include a hermetic housing assembly 12, first and second bearing housing assemblies 14, 16, a motor assembly 18, a compression mechanism 20, a discharge port or fitting 24, a suction port or fitting 28, and a suction conduit (or suction hopper) 30.

As shown in fig. 1, the housing assembly 12 may form a compressor housing and may include a cylindrical housing 32, an end cap 34 at an upper end of the cylindrical housing 32, a laterally extending partition 36, and a base 38 at a lower end of the cylindrical housing 32. The housing 32, base 38, and partition 36 may cooperate to define a suction pressure chamber 39. The end cap 34 and the partition 36 may define a discharge pressure chamber 40. The partition 36 may separate the discharge pressure chamber 40 from the suction pressure chamber 39. A discharge pressure passage 43 may extend through partition 36 to provide communication between compression mechanism 20 and discharge pressure chamber 40. The suction fitting 28 may be attached to the housing assembly 12 at the opening 46.

As shown in fig. 1, the first bearing housing assembly 14 may be disposed within the suction pressure chamber and may be fixed relative to the housing 32. The first bearing housing assembly 14 may include a first main bearing housing 48 and a first bearing 50. First main bearing housing 48 may house a first bearing 50 therein. First main bearing housing 48 may fixedly engage shell 32 and may axially support compression mechanism 20.

As shown in fig. 1, the motor assembly 18 may be disposed within the suction pressure chamber 39 and may include a stator 60 and a rotor 62. The stator 60 may be press fit into the housing 32. The rotor 62 may be press-fit on the drive shaft 64 and may transmit rotational power to the drive shaft 64. The drive shaft 64 may be rotatably supported by the first bearing housing assembly 14 and the second bearing housing assembly 16. The drive shaft 64 may include an eccentric crankpin 66 having a crankpin flat.

As shown in fig. 1, the compression mechanism 20 may be disposed within the suction pressure chamber 39 and may include an orbiting scroll 70 and a non-orbiting scroll 72. First scroll member or orbiting scroll 70 may include an end plate 74 and a spiral wrap 76 extending from end plate 74. The cylindrical hub 80 may protrude downwardly from the end plate 74. A drive bushing may be provided in the hub 80 and may receive the crank pin 66. Oldham coupling 84 may engage orbiting scroll member 70 and non-orbiting scroll member 72 to prevent relative rotation therebetween.

As shown in fig. 1, the second or non-orbiting scroll member 72 may include an end plate 86 and a spiral wrap 88 projecting downwardly from the end plate 86. Spiral wrap 88 may meshingly engage spiral wrap 76 of orbiting scroll member 70 to create a series of moving fluid pockets. The fluid pockets defined by the spiral wraps 76, 88 may decrease in volume as they move from a radially outer position (at suction pressure) to a radially intermediate position (at intermediate pressure) to a radially inner position (at discharge pressure) throughout the compression cycle of the compression mechanism 20. As shown in fig. 1, 2, and 4, a suction inlet 89 may be formed in the non-orbiting scroll member 72 and may provide fluid communication between the suction conduit 30 and a radially outermost fluid chamber 93 (fig. 1) formed by the spiral wraps 76, 88.

Non-orbiting scroll member 72 may include an upper scroll member 94 mounted to end plate 86 (lower scroll member). Upper scroll 94 is mounted to an upper surface 96 of end plate 86. Fasteners (e.g., threaded fasteners) may extend through mounting apertures 98 (fig. 4) of upper scroll 94 and into mounting apertures 100 (fig. 4) in end plate 86. As shown in FIG. 1, upper scroll 94 may include an upper annular recess 102 that may receive a floating seal assembly 104. As will be described in greater detail below, a portion of suction conduit 30 may be captured or sandwiched between upper scroll 94 and end plate 86.

Upper scroll 94 may also include a lower recess 106 (fig. 2), and a variable compression ratio valve 108 may be disposed in lower recess 106. Each of the variable compression ratio valves 108 may include a valve member (e.g., reed valve) 110 and a valve seat 112. Valve member 110 is movable relative to end plate 86 to selectively open and close variable compression ratio ports 114 formed in end plate 86. Variable compression ratio port 114 is in fluid communication with the intermediate pressure chamber formed by spiral wraps 76, 88. Variable compression ratio valve 108 selectively allows and prevents fluid communication between the intermediate-pressure chamber and discharge chamber 40. Variable compression ratio valve 108 may be mounted to end plate 86 by fasteners (e.g., pins or threaded fasteners) that engage apertures 109 (fig. 4) in end plate 86. A seal (e.g., an O-ring) 107 may surround the lower recess 106 and may sealingly engage the end plate 86 and the upper scroll 94.

As shown in FIG. 2, upper scroll 94 may also include a central hub 116 that may define a valve guide 118 and one or more apertures 120. The orifice 120 may be in fluid communication with the undercut 106 and the discharge chamber 40. The valve guide 118 may movably engage a portion of the discharge valve 122 (and guide movement of a portion of the discharge valve 122). For example, the valve guide 118 may include an aperture that reciprocally receives the stem 124 of the discharge valve 122. The body 126 of the discharge valve 122 may selectively open and close a discharge passage 128 formed in the end plate 86 to selectively permit and prevent fluid communication between the discharge passage 128 and the discharge chamber 40. Discharge passage 128 receives fluid from the discharge pressure chamber formed by spiral wraps 76, 88.

Suction conduit 30 may direct working fluid at suction pressure from suction fitting 28 to suction inlet 89 of non-orbiting scroll member 72 such that the working fluid may be directed into radially outermost fluid chamber 93 and subsequently compressed by compression mechanism 20. As shown in fig. 1, 2, and 4, a portion of the suction conduit 30 may snap into engagement with a wall 90 of the non-orbiting scroll 72 (e.g., a wall defining a lower end of the suction inlet 89), and another portion of the suction conduit 30 may be captured or clamped between the upper scroll 94 and the end plate 86. The suction catheter 30 may include a body 130 and a mounting flange 132. The body 130 may include a first end 134 and a second end 136. An inlet opening 138 (fig. 3-5) may be formed at the first end 134 of the body 130 or near the first end 134 of the body 130, and an outlet opening 140 (fig. 2 and 6) may be formed at the second end 136 of the body 130 or near the second end 136 of the body 130. The first end 134 may be adjacent to the suction fitting 28 such that fluid may flow from the suction fitting 28 into the inlet opening 138. In some configurations, the inlet opening 138 may be generally aligned with the suction fitting 28. In some configurations, the first end 134 may be open (or include an orifice) to allow a portion of the working fluid from the suction fitting 28 to flow toward the motor assembly 18 (rather than toward the suction inlet 89).

The outlet opening 140 may provide fluid communication between the suction conduit 30 and the compression mechanism 20. That is, the working fluid flowing into the suction duct 30 through the inlet opening 138 may exit the suction duct 30 through the outlet opening 140. Working fluid may be directed from outlet opening 140 into radially outermost fluid chamber 93 and then compressed by compression mechanism 20.

Mounting tabs or clips 142 (fig. 1, 2, and 6) may extend from the body 130, and the mounting tabs or clips 142 may be disposed at or near the bottom of the outlet opening 140. As shown in fig. 2 and 6, the clip 142 may include a first member 144 and a second member 146 extending perpendicular to the first member 144. When suction conduit 30 snaps into engagement with non-orbiting scroll member 72, clip 142 may extend at least partially into suction inlet 89 and engage wall 90 (i.e., clip 144 may snap onto wall 90).

The mounting flange 132 may extend from the second end 136 of the body 130 and may be disposed at a tip of the outlet opening 140 or near a tip of the outlet opening 140. As shown in fig. 2 and 3, the mounting flange 132 may be received in a recess (or notch) 147 formed in the lower side of the upper scroll 94 such that a surface 149 defining the recess 147 may contact the mounting flange 132. As shown in fig. 4-6, the mounting flange 132 may include one or more locating pins (or tabs) 148 extending therefrom. The locating pin 148 may be received in a bore (or opening) 150 formed in the non-orbiting scroll member 72. In the example shown in fig. 1-6, apertures 150 that receive the locating pins 148 are formed in the end plate 86.

When suction conduit 30 is fully mounted to non-orbiting scroll member 72, clip 142 engages wall 90 (as described above), locating pin 148 is received in aperture 150, lower surface 152 of mounting flange 132 is in contact with surface 96 of end plate 86, and upper surface 154 of mounting flange 132 is in contact with upper scroll member 94 (e.g., surface 149) such that mounting flange 132 is captured (or clamped) between upper scroll member 94 and end plate 86. This mounting configuration for the suction conduit 30 securely retains the suction conduit 30 relative to the non-orbiting scroll member 72 in an easy to install manner. In this manner, the engagement between pin 148 and aperture 150 limits or prevents inadvertent disengagement of suction conduit 30 from non-orbiting scroll 72 when mounting flange 132 is captured or clamped between upper scroll 94 and end plate 86.

In some configurations, a surface 149 of the upper scroll 94 that contacts the mounting flange 132 may be defined by one or more mounting tabs 156 (fig. 3 and 4) of the upper scroll 94 (or partially defined by one or more mounting tabs 156 of the upper scroll 94). Mounting tabs 156 are circumferentially spaced from one another and may extend radially outward from an outer edge 157 of upper scroll 94. Mounting boss 156 may include a mounting aperture 98, and a fastener may extend through mounting aperture 98 to secure upper scroll 94 to end plate 86, as described above.

In some configurations, the suction conduit 30 may include one or more ribs 160 extending from the second end 136 of the body 130 to the mounting flange 132. The one or more ribs 160 provide rigidity and strength to the suction conduit 30 and may also provide a convenient location for an operator to grasp the suction conduit 30 during installation of the suction conduit 30 onto the non-orbiting scroll member 72.

Referring now to fig. 7-11, another non-orbiting scroll 272 and suction conduit 230 are provided. The non-orbiting scroll 272 and the suction conduit 230 may be incorporated into the compressor 10 described above in place of the non-orbiting scroll 72 and the suction conduit 30. The structure and function of the non-orbiting scroll 272 and the suction conduit 230 may be similar or identical to the structure and function of the non-orbiting scroll 72 and the suction conduit 30 described above, except for the differences described below.

Like non-orbiting scroll 72, non-orbiting scroll 272 includes a lower scroll or end plate 286 and an upper scroll 294. Like upper scroll 94, upper scroll 294 includes recess (or notch) 347, with recess (or notch) 347 including surface 349. As described above, the mounting flange 332 of the suction conduit 230 may be received in the recess 347 such that the mounting flange 332 may be captured or clamped between the surface 349 of the upper scroll 294 and the upper surface 296 of the end plate 286.

As described above, the surface 349 of the upper scroll 294 that contacts the mounting flange 332 may be defined by one or more mounting bosses 356 of the upper scroll 294 (or partially defined by one or more mounting bosses 356 of the upper scroll 294). The mounting boss 356 may include a mounting aperture 298 through which a fastener may extend to secure the upper scroll 294 to the end plate 286, as described above. In the configuration shown in fig. 7-9, the mounting boss 356 defining the surface 349 may also include an aperture (or opening) 350 (fig. 8 and 9) that receives a locating pin (or tab) 348 extending from the mounting flange 332 of the suction conduit 230. In this manner, the engagement between the pin 348 and the aperture 350 limits or prevents the inadvertent disengagement of the suction conduit 230 from the non-orbiting scroll 272 when the mounting flange 332 is captured or clamped between the upper scroll 294 and the end plate 286. Like suction conduit 30, suction conduit 230 may include a mounting tab or clip 342, with mounting tab or clip 342 engaging wall 290 of end plate 286 to further secure suction conduit 230 to non-orbiting scroll 272.

Referring now to fig. 12-16, another non-orbiting scroll 472 and suction conduit 430 are provided. The non-orbiting scroll 472 and the suction conduit 430 may be incorporated into the compressor 10 described above in place of the non-orbiting scroll 72, 272 and the suction conduit 30, 230. The structure and function of the non-orbiting scroll 472 and the suction conduit 430 may be similar or identical to the structure and function of the non-orbiting scroll 272 and the suction conduit 230 described above, except for the differences described below.

Like the non-orbiting scroll 272, the non-orbiting scroll 472 includes a lower scroll or end plate 486 and an upper scroll 494. Like the upper scroll 294, the upper scroll 494 includes a recess (or notch) 547, the recess (or notch) 547 including a surface 549. As described above, the mounting flange 532 of the suction conduit 430 may be received in the recess 547 such that the mounting flange 532 may be captured or clamped between the surface 549 of the upper scroll 494 and the upper surface 496 of the end plate 486. Like the suction catheter 230, the suction catheter 430 may include mounting tabs or clips 542 that engage the wall 490 of the endplate 486.

As described above, the surface 549 of the upper scroll 494 that contacts the mounting flange 532 may be defined by one or more mounting bosses 556 of the upper scroll 494 (or defined in part by one or more mounting bosses 556 of the upper scroll 494). The mounting boss 556 may include a mounting aperture 498 (fig. 13 and 14) through which a fastener may extend to secure the upper scroll 494 to the end plate 486, as described above. In the configuration shown in fig. 12-16, the mounting boss 556 defining the surface 549 may further include a locating pin (or protrusion) 548 (fig. 14), the locating pin 548 being received in an aperture (or opening) 550 formed in the mounting flange 532 of the suction conduit 430. In this manner, the engagement between the pin 548 and the bore 550 limits or prevents the inadvertent disengagement of the suction conduit 630 from the non-orbiting scroll 672 when the mounting flange 532 is captured or clamped between the upper scroll 494 and the end plate 486.

In some configurations, the apertures 550 in the mounting flange 532 may be aligned with corresponding mounting apertures 498 in the upper scroll 494 and corresponding mounting apertures in the end plate 486. In this configuration, the pins 548 may be replaced with fasteners (e.g., threaded fasteners) that extend through the apertures 498, 550 and into mounting apertures in the end plate 486.

Referring now to fig. 17-22, another non-orbiting scroll 672 and suction conduit 630 are provided. The non-orbiting scroll 672 and the suction conduit 630 may be incorporated into the compressor 10 described above in lieu of the non-orbiting scroll 72, 272, 472 and the suction conduit 30, 230, 430. The structure and function of the non-orbiting scroll 672 and the suction conduit 630 may be similar or identical to those of the non-orbiting scroll 72, 272, 472 and the suction conduit 30, 230, 430 described above, except for the differences described below.

Like non-orbiting scroll member 72, non-orbiting scroll member 672 includes a lower scroll member or end plate 686 and an upper scroll member 694. Like upper scroll 94, upper scroll 694 includes a recess (or notch) 747, the recess (or notch) 747 including a surface 749 (as shown in fig. 20). As described above, the mounting flange 732 of the suction conduit 630 may be received in the recess 747 such that the mounting flange 732 may be captured or clamped between the surface 749 of the upper scroll 694 and the upper surface 696 of the end plate 686. Like the suction catheter 30, the suction catheter 630 may include a mounting tab or clip 742 that engages the wall 690 of the end plate 686.

As shown in fig. 17 and 20, the upper scroll 694 may include a groove (or opening) 770 disposed adjacent to the recess 747. As shown in fig. 17 and 19, the end plate 686 may also include a groove (or opening) 772 disposed adjacent to the suction inlet 689 of the non-orbiting scroll 672. As shown in fig. 17, the grooves 770, 772 may be generally aligned with each other when the upper scroll 694 is mounted on the end plate 686.

The distal end of the mounting flange 732 may include a first protrusion or lip 776 and a second protrusion or lip 778. A first lip 776 may extend upwardly from the mounting flange 732 and may be received in a groove 770 in the upper scroll 694 (as shown in fig. 17). The second lip 778 may extend downwardly from the mounting flange 732 and may be received in a groove 772 in the end plate 686 (as shown in fig. 17). In this manner, the engagement between the lips 776, 778 and the grooves 770, 772, respectively, limit or prevent the inadvertent disengagement of the suction conduit 630 from the non-orbiting scroll 672 when the mounting flange 732 is captured or clamped between the upper scroll 694 and the end plate 686. As shown in fig. 17, the lips 776, 778 of the mounting flange 732 and the body 775 cooperate to form a T-shaped cross-section.
