Abstract
A compressor may include a casing, and a compression device installed inside of the casing and that compresses the refrigerant while rotating by receiving a rotational force of an electric motor through a rotational shaft. A high/low pressure separation plate may be installed at an upper portion of the compression device, and an insulation plate may be provided to block the high/low pressure separation plate and the suction tube from each other by being located therebetween. The insulation plate may reduce heat transfer between a refrigerant discharge space having a high temperature located at the upper portion of the high/low pressure separation plate and a refrigerant suction space having a relatively low temperature located at a lower portion of the high/low pressure separation plate.
