Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
Example embodiments are provided so that this disclosure will be thorough and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
The terminology used herein is for the purpose of describing example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” 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 are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to 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 may be directly on, engaged, connected 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 words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). 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,” “beneath,” “below,” “lower,” “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 “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can 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.

The non-orbiting scroll 72 may include an upper scroll piece 94 that is mounted to the end plate 86 (lower scroll piece). The upper scroll piece 94 is mounted to an upper surface 96 of the end plate 86. Fasteners (e.g., threaded fasteners) may extend through mounting apertures 98 (
The upper scroll piece 94 may also include a lower recess 106 (
As shown in
The suction conduit 30 may direct working fluid at a suction-pressure from the suction fitting 28 to the suction inlet 89 of the non-orbiting scroll 72 so that working fluid can be directed into the radially outermost fluid pocket 93 and subsequently compressed by the compression mechanism 20. As shown in
The outlet opening 140 may provide fluid communication between the suction conduit 30 and the compression mechanism 20. That is, working fluid that flows into the suction conduit 30 through the inlet opening 138 may exit the suction conduit 30 through the outlet opening 140. From the outlet opening 140, the working fluid may be directed into the radially outermost fluid pocket 93 and subsequently compressed by the compression mechanism 20.
A mounting tab or clip 142 (
The mounting flange 132 may extend from the second end 136 of the body 130 and may be disposed at or near a top of the outlet opening 140. The mounting flange 132 may be received in a recess (or notch) 147 formed in a lower side of the upper scroll piece 94 such that a surface 149 defining the recess 147 may contact the mounting flange 132, as shown in
When the suction conduit 30 is fully mounted to the non-orbiting scroll 72, the clip 142 is engaged with the wall 90 (as described above), the locating pins 148 are received in apertures 150, a lower surface 152 of the mounting flange 132 is in contact with the surface 96 of the end plate 86, and an upper surface 154 of the mounting flange 132 is in contact with the upper scroll piece 94 (e.g., the surface 149) such that the mounting flange 132 is captured (or clamped) between the upper scroll piece 94 and the end plate 86. This mounting configuration for the suction conduit 30 securely retains the suction conduit 30 relative to the non-orbiting scroll 72 in a manner that is simple to install. In this manner, while the mounting flange 132 is captured or clamped between the upper scroll piece 94 and the end plate 86, the engagement between the pins 148 and the apertures 150 restricts or prevents the suction conduit 30 from being inadvertently disengaged from the non-orbiting scroll 72.
In some configurations, the surface 149 of the upper scroll piece 94 that contacts the mounting flange 132 may be defined by (or partially defined by) one or more mounting lobes 156 (
In some configurations, the suction conduit 30 may include one or more ribs 160 that extend from the second end 136 of the body 130 to the mounting flange 132. The one or more ribs 160 provide rigidity and strength for the suction conduit 30 and may also provide a convenient location for an operator to grasp the suction conduit 30 during installation onto the non-orbiting scroll 72.
