Embodiment Construction

[0043] Referring to the accompanying drawings, a detailed description will now be given of the embodiments. Where possible, like reference numerals are used to designate like elements, and repeated descriptions are omitted.

[0044] refer to figure 1 , when the scroll compressor 1 is working, the floating plate 60 moves up and down continuously and is in contact with the surface of the back pressure chamber BP. Therefore, high lubricity and high wear resistance may be required. The second scroll 40 is manufactured by casting and formed of cast iron. If the lip seal repeatedly performs sliding motion along the surface of the second scroll 40, when the second scroll 40 has a rough surface due to its material, the sealing performance may be affected by wear of the lip seal. And reduce. However, due to the structure of the scroll compressor 1, it may be difficult to process the surface roughness of the second scroll 40 to a desired level. In addition, during processing the su...

Abstract

The present invention provides a scroll compressor and a backpressure chamber assembly for the scroll compressor. The scroll compressor may include a casing, a discharge cover, a main frame, a first scroll supported by the main frame, and a second scroll forming a suction chamber, an intermediate pressure chamber and a discharge chamber together with the first scroll . The scroll compressor may also include a back pressure plate coupled to the second scroll. The back pressure plate may include a cavity with which the intermediate pressure chamber of the second scroll communicates. The scroll compressor may also include a floating plate movably coupled to the back pressure plate to seal the upper portion of the cavity.

Description

technical field [0001] A compressor is disclosed herein, and more particularly, a scroll compressor is disclosed. Background technique [0002] Scroll compressors are known. However, such compressors have various disadvantages. [0003] A scroll compressor is a compressor that utilizes a first or orbiting scroll with a spiral wrap and a second or fixed scroll with a spiral wrap, the first scroll performing relative to the second scroll orbiting motion. When the first scroll and the second scroll are engaged with each other in operation, as the first scroll performs an orbiting motion, the pressure chamber formed between the first scroll and the second scroll capacity can be reduced. Accordingly, the pressure of the fluid in the pressure chamber may be increased, and the fluid is discharged from the discharge port formed at the central portion of the second scroll. [0004] When the first scroll performs an orbiting motion, the scroll compressor may continuously perform ...
