Abstract: A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented.

Abstract: A scroll compressor includes a motor portion fixed in an inner space of a casing, a compression portion fixed to the inner space of the casing at one side of the motor portion in an axial direction, a rotation shaft to transmit a driving force from the motor portion to the compression portion, and a flow path guide provided in a discharge space between the motor portion and the compression portion and provided with a guide outlet communicating with the discharge space and opened in a direction toward the rotation shaft. Therefore, most of refrigerant discharged to the discharge space through the flow path guide is moved toward an air gap to enhance an oil separation effect, and thus a normal operation point of the air conditioner can be accelerated.

Abstract: A scroll compressor is provided that may include a first compression chamber, a second compression chamber separated from the first compression chamber, and having a greater compression ratio than the first compression chamber, a first discharge port that communicates with the first compression chamber and provided with a first discharge inlet and a first discharge outlet, and a second discharge port separated from the first discharge port, communicating with the second compression chamber, and provided with a second discharge inlet and a second discharge outlet, the second discharge inlet having a larger sectional area than the first discharge inlet. This configuration may prevent a discharge delay in advance in each compression chamber, and thus, preventing a compression loss.
