(a) Field of the Invention
The present invention is related to a fixation means, and more particularly to one that is provided between stationary scroll and frame within a scroll-type compressor to eliminate operating noise or frustrated operation due to unpredictable change or narrowed ideal spacing between the positioning post and stationary scroll because that the positioning post is deformed.
(b) Description of the Prior Art
Referring to
In addition to holding the stationary scroll 10 in position, the frame 40 supports and couples the orbiting scroll 20, the spindle and other related components. As illustrated in
Since the frame 40 and the retaining spacer 70 is coupled by means of the bolt 60 and the screwed hole 51, a comparatively strong force must be applied to lock the bolt 60 into the screwed hole 51 at the expense of the assembly precision of other components. In worse case, the positioning post 41 is vulnerable to be deformed when subject to the compression from the bolt 60 and the screwed hole 51 as illustrated in
The primary purpose of the present invention is to provide a means for the assembly of a scroll-type compressor for assurance of the assembly quality of the compressor and eliminating abnormal operation noise or prevention of smooth operation due to the deformed positioning post narrows down or changes the ideal spacing between the positioning post and the stationary scroll.
To achieve the purpose, one or multiple positioning holes is provided to the positioning post of the frame and a positioning element lock a retaining spacer to the frame to contain and thus limit the stationary scroll and to define an ideal spacing between the positioning post of the frame and the stationary scroll. Accordingly, the ideal spacing will not be affected once the rod of the positioning element is inserted into the positioning hole to lock up the positioning post to secure the retaining spacer to the frame.
Similar to the prior art, inside the housing of the compressor in the present invention is also segregated into a low-pressure chamber and a high-pressure chamber by means of a separation block, and a stationary scroll and an orbiting scroll are disposed below the separation block in the low-pressure chamber. Wherein, the stationary scroll is placed on a frame while the orbiting scroll as driven by a spindle of the compressor revolves on the axis of the stationary scroll, instead of its own axis to change the volume of a coolant by changing the volume between the stationary scroll and the orbiting scroll. Accordingly, the coolant is sucked and compressed upon entering into the low-pressure chamber for the coolant circulation pipeline to execute heat exchange.
Referring to
As illustrated in
Wherein, the location where the positioning element 80 to the frame 40 is far away from the stationary scroll 10, or the scope of the ideal spacing A between the stationary scroll 10 and the positioning post 41 for the interlocking between the positioning element 80 and the positioning hole 52 for maintaining the assembly quality of the compressor and effectively eliminating the defects of abnormal operation noise or prevention of a smooth operation due to narrowed or unpredictable change to the ideal spacing between the positioning post and the stationary scroll caused by deformed positioning post 41.
The prevent invention provides an improved means for the assembly of a scroll-type compressor for assurance of assembly quality of the stationary scroll, and the application for a utility patent is duly filed accordingly. However, it is to be noted that that the preferred embodiments disclosed in the specification and the accompanying drawings are not limiting the present invention; and that any construction, installation, or characteristics that is same or similar to that of the present invention should fall within the scope of the purposes and claims of the present invention.
