Benefits of technology
[0007] 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.
[0008] 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.
Problems solved by technology
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 FIG. 2 to further narrow down the ideal space A between the stationary scroll 10 and the positioning post 41 to result in abnormal operation noise or prevention of a smooth operation of the scroll-type compressor.

Embodiment Construction
[0013] 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.
[0014] Referring to FIG. 3 for a construction of the stationary scroll and the frame, one or multiple positioning holes 52 is disposed on a positioning post 41 of the frame 40. A positioning element 80 locks a retaining ...

A scroll-type compressor assembly means has one or multiple positioning holes provided on a positioning post of the frame, and a positioning element to fix a retaining spacer to the frame for the retaining spacer to limit the stationary scroll and to define an ideal spacing between the positioning post and the stationary scroll; the ideal spacing not affected by the locking location of the positioning element to the positioning post that is far away from the ideal spacing or the stationery scroll for assurance of assembly quality of the compressor and prevention of operation 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.
Description
BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] 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. [0003] (b) Description of the Prior Art [0004] Referring to FIG. 1 for a fixation means for the stationary scroll in a scroll-type compressor generally available in the market, interior of the housing of the compressor is segregated by means of a separation block 30 into a low-pressure chamber and a high-pressure chamber; and a stationary scroll 10 and an orbiting scroll 20 are disposed at where below the separation block 30 on the lower-pressure chamber side. Wherein, the stationary scroll is placed on a frame 40 and its orbiting scroll 20 as drive...
