Abstract: A scroll compressor includes a main housing. A driving part configured to generate torque and a compression part driven by the driving part are accommodated in the main housing. The compression part includes a fixed scroll and an orbiting scroll that engages with the fixed scroll to form a compression chamber in which a refrigerant is compressed. The torque of the driving part is transmitted to the compression part by a driving shaft. The driving shaft is rotatably supported by a main bearing positioned in a low pressure region adjacent to the driving part. Accordingly, since the main bearing is disposed in a low pressure region, a load applied to the main bearing may be decreased.

Abstract: A motor operated compressor includes an orbiting scroll that defines a compression chamber together with a fixed scroll. The compressor includes a main frame disposed around and supporting the orbiting scroll. The main frame defines a back-pressure chamber together with the orbiting scroll. The compressor includes a groove disposed in one of the orbiting scroll and the main frame. A first sealing member is inserted into the groove. A second sealing member is inserted into the groove to elastically press the first sealing member into close contact with the orbiting scroll or the main frame. A radial distance (a) between an outer wall of the groove and the first sealing member is 6 to 8% (0.06≤a/W≤0.08) of a difference (W) between an outer radius (OR) and an inner radius (IR) of the first sealing member (W=OR−IR).

Abstract: A motor-operated compressor includes a casing having a motor chamber that accommodates a driving motor. The compressor also includes a frame. A first scroll having a first spiral wrap is connected to one side of the frame. A second scroll is provided between the frame and the first scroll. The second scroll has a second spiral wrap that engages with the first spiral warp to form compression chambers between the first and second spiral wraps. The compressor also includes a rotation shaft connected at one end to the driving motor and at an opposite end to the second scroll. The compressor includes a back pressure space defined by a balance weight axially separated from a rear surface of the second scroll. A back pressure passage fluidly connects the compression chambers with the back pressure space.
