Floating sealer and the compressor therewith

[0032] Example one

[0033] Referring to Figure 1, the compressor provided in this embodiment includes a sealed housing 2 in which a high and low pressure partition plate 21 is provided, and a fixed scroll 3 is provided under the high and low pressure partition plate 21 and cooperates with the fixed scroll 3 In order to realize the floating sealing function of the sealing cover 4 and the sealing rings 51, 52, 53, the movable scroll 6 installed opposite to the fixed scroll 3 is arranged below the fixed scroll 3, so that the two scrolls have a suction pressure zone 300 and a discharge pressure zone. A compression chamber with a gradually changing volume is generated between 400 and the sealed housing 2 is provided with a bearing seat 7 for installing the fixed scroll 3 and making it have limited axial movement relative to the movable scroll 6, and the bottom of the movable scroll 6 is with The crankshaft 8 is matched, the crankshaft 8 is matched with the motor assembly 9, the crankshaf

[0042] Example two

[0043] Referring to Figure 5, the difference between the compressor with a floating sealing device provided in the second embodiment and the first embodiment is that the top end of the sealing cover 4 and the high and low pressure partition plate cooperate with the sealing mechanism used to separate the suction pressure zone and the discharge pressure zone The difference is that in the first embodiment, the groove 43 is matched with the sealing ring 53. In the second embodiment, the closed boss 44 integrally formed at the top of the sealing cover 4 and the sealing pad 211 provided at the bottom of the high and low pressure partition plate are used in the second embodiment. . This embodiment can achieve the same purpose and function as the first embodiment.

[0044] Example three

[0045] Please refer to Fig. 6, the third embodiment provides a compressor with a floating seal device and the difference between the second embodiment is that the boss on the top of the end plate of the fixed scroll 3 is a first-stage boss, which is labeled 310 in Fig. 6, and the seal The groove provided at the bottom of the cover 4 is correspondingly a first-stage groove, and the upper end of the boss 310 is partially embedded in the groove, so that a middle pressure cavity 100 is formed between the top surface of the boss 310 and the bottom surface of the groove. The first sealing element is arranged between the outer side wall of the boss 310 and the outer side wall of the groove to isolate the medium pressure chamber 100 from the suction pressure zone 300, and the second sealing element is arranged on the inner side wall of the boss 310 and the groove Between the inner side walls, the medium pressure chamber 100 is separated from the discharge pressure zone
