摘要： 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.

摘要： A scroll compressor is provided that may include a casing including a rotational shaft, a first scroll rotated by rotation of the rotational shaft, the first scroll including a first head plate and a first wrap that extends from the first head plate in a first direction, and a second scroll that defines a plurality of compression chambers together with the first scroll, the second scroll including a second head plate and a second wrap that extends from the second head plate in a second direction. Each of the first and second wraps spirally may extend from an outer end toward an inner start end, and the first wrap may have a thickness greater than a thickness of the second wrap.

摘要： A scroll compressor includes a casing accommodating a rotary shaft and a driving unit, a first scroll making an orbiting movement by the rotary shaft, a second scroll engaged with the first scroll to form a compression chamber and having a bypass hole bypassing a refrigerant sucked into the compression chamber to an internal space of the casing, and a back-pressure chamber assembly pressing the second scroll toward the first scroll, wherein the back-pressure chamber assembly includes: a back-pressure space, a first valve unit allowing the bypass hole and the internal space of the casing to selectively communicate with each other, and a second valve unit opened and closed to selectively supply the refrigerant of the back-pressure space to the first valve unit to operate the first valve unit, and positioned to be fixed to the casing.
