Abstract: A scroll compressor is provided which is configured such that an arcuate section may be formed from a suction end of a wrap to a first point to increase a suction volume, and a logarithmic spiral section in which a wrap thickness increases may be formed from a second point to a discharge end of the wrap. This may increase a volume ratio of the compressor so as to increase a capacity of the compressor and prevent damage to the wrap due to a high compression ratio operation, thereby enhancing reliability of the compressor.

Abstract: A scroll compressor is disclosed. The scroll compressor includes a rotating shaft coupling portion axially extending from a central portion of an orbiting end plate to radially overlap an orbiting wrap, such that an eccentric portion of a rotating shaft is coupled thereto, and a portion of the orbiting wrap may extend from an end surface of the rotating shaft coupling portion facing a fixed end plate. With the configuration, a distance between bearing reaction force and gas reaction force acting on the orbiting scroll can be reduced, to stabilize a behavior of the orbiting scroll and thus reduce back pressure, thereby decreasing friction loss between scrolls. Simultaneously, compression chambers can be formed even in a central portion of the orbiting scroll, which can increase a compression ratio and improve volumetric efficiency.

Abstract: A scroll compressor includes a casing, a main frame, a rotating shaft, an orbiting scroll, a fixed scroll configured to engage the orbiting scroll to form a compression chamber, and an Oldham ring slidably coupled to the orbiting scroll to prevent rotation of the orbiting scroll. The Oldham ring includes: a ring body provided between the main frame and the orbiting scroll to be supported in an axial direction of the rotating shaft, and a key portion extending in the axial direction from the ring body and slidably inserted into a key accommodating portion provided in the orbiting scroll, the main frame, or the fixed scroll. The ring body or the key portion includes an oil supply passage for guiding oil accumulated in a member on which the ring body is supported to between the key portion and the key accommodating portion.
