Abstract: A scroll compressor (100) comprises an orbiting scroll component (160); a fixed scroll component (150); sealing components (PS1, PS2, PS3, PS4, PS5, PS6), wherein the sealing components match a concave part (158) on the orbiting scroll component (50) so as to form a back pressure chamber (BC) together, and the sealing components are constructed to separate the back pressure chamber from a high-pressure side and a low-pressure side in the scroll compressor (100); and a leakage path (L), wherein the leakage path (L) is constructed to allow fluid in the back pressure chamber (BC) to leak.

Abstract: Disclosed are a main bearing housing (40) for a scroll compressor, a dynamic scroll component (60) for the scroll compressor and the scroll compressor. The main bearing housing (40) comprises an anti-thrust surface (S1) for supporting the dynamic scroll component (60), an uneven construction (W) is formed on at least one portion of the anti-thrust surface (S1) to enable a lubricant to form a fluid dynamic pressure lubricating oil film between the main bearing housing (40) and the dynamic scroll component (60). The dynamic scroll component (60) comprises an anti-thrust surface (S2) for being supported by the main bearing housing (40), wherein an uneven construction (W) is formed on at least one portion of the anti-thrust surface (S2) to enable the lubricant to form a fluid dynamic pressure lubricating oil film between the main bearing housing (40) and the dynamic scroll component (60). The scroll compressor comprises at least one of the main bearing housing (40) and the dynamic scroll component (60).

Abstract: A scroll compressor (10), comprising a fixed scroll (150), a movable scroll (160) and a drive shaft (30); the scroll compressor (10) further comprises a movable scroll counterweight (40); the movable scroll counterweight (40) is configured to rotate with the drive shaft (30); and the centrifugal force of the movable scroll counterweight (40) caused by the rotation acts on the hub (162) of the movable scroll (160). The above structure can effectively reduce the impact of the centrifugal force of the movable scroll on the radial seal of a scroll component, thus achieving proper radial sealing force between the fixed scroll and the movable scroll at any rotating speed.

Abstract: A method includes forming a sheet of material having first, second, third, and fourth ends. The third and fourth ends extend longitudinally between the first and second ends. First and second protrusions are formed at the first end. The first and second protrusions extend longitudinally outwardly from an edge of the first end. The third and fourth ends are coupled to one another to create a longitudinally extending compressor shell having a stepped region at the edge of the first end where the third and fourth ends meet.

Abstract: A scroll compressor includes a discharge valve assembly having a valve member, a valve stop supported within the compressor shell and including an aperture there through and a communication member. The communication member defines a fluid passage extending into the discharge chamber from the valve stop toward the first discharge outlet in the discharge chamber and provides fluid communication between the aperture in the valve stop and a location downstream of the valve stop. A first side of the valve member abuts the valve stop when in an open position and the valve stop provides communication between the first side of the valve member and the communication member via the aperture.

Abstract: A rotary compressor, comprising: a housing (12), comprising a lubricant oil storage part for containing lubricating oil; a compression mechanism (20) disposed in the housing (12); a driving mechanism (30) driving the compression mechanism (20), the driving mechanism (30) comprising a rotation shaft (50), through-holes (54, 56) extending along the axial direction of the rotating shaft (50) are disposed inside the rotating shaft (50), and the rotation shaft (50) is in fluid connection with the lubricating oil storage part via the through-holes (54, 56); and an oil level sensor (120) in fluid connection with the through-holes (54, 56) inside the rotation shaft (50) via a pressurized collection channel (110). Also disclosed is a rotation mechanism, comprising an oil level sensor (120) in fluid connection with the through-holes (54, 56) inside the rotation shaft (50) via the pressurized collection channel (110).

Abstract: A compressor includes a shell, a compression mechanism supported within a suction pressure region of the shell and including a discharge outlet in communication with the discharge chamber, and a discharge valve assembly. The discharge valve assembly includes a valve member, a valve stop including an opening therethrough, and a communication member defining a fluid passage and extending into the discharge chamber from the valve stop toward the discharge outlet in the discharge chamber to provide fluid communication between the opening in the valve stop and a location downstream of the valve stop.

Abstract: A compressor includes a shell formed from a piece of material having first, second, third, and fourth ends. The third and fourth ends extend between the first and second ends and are coupled to one another. The first and second ends form longitudinal ends of the shell. The first end includes an edge having first and second protrusions extending longitudinally outwardly therefrom. The edge includes a stepped region at a location where the third end extends longitudinally beyond a portion of the edge proximate the fourth end.
