Abstract

A scroll compressor may include a casing having a low pressure portion and a high pressure portion, a suction pipe that communicates with the low pressure portion and a discharge pipe that communicates with the high pressure portion, a drive motor installed inside of the low pressure portion, an orbiting scroll coupled to the drive motor to perform an orbiting motion, a non-orbiting scroll engaged with the orbiting scroll to form a compression chamber, and a refrigerant guide provided on the non-orbiting scroll to guide a refrigerant suctioned into the low pressure portion to be suctioned into the compression chamber, whereby an increase in specific volume of refrigerant suctioned into the compression chamber may be suppressed, and thus, an amount of refrigerant suctioned into the compression chamber may increase, thereby improving efficiency of the compressor.

Description

technical field

[0001] The present invention relates to a scroll compressor, in particular, to a suction flow path. Background technique

[0002] In a scroll compressor, an orbiting scroll and a non-orbiting scroll are meshed together to form two pairs of compression chambers while the orbiting scroll orbits relative to the non-orbiting scroll.

[0003] The compression chamber is composed of a suction pressure chamber formed on the periphery, an intermediate pressure chamber continuously formed in which the volume of the suction pressure chamber gradually decreases toward the center, and a discharge pressure chamber connected to the center side of the intermediate pressure chamber. Usually, the suction pressure chamber is formed penetrating the side surface of the non-orbiting scroll, the intermediate pressure chamber is sealed, and the discharge pressure chamber is formed penetrating the end plate portion of the non-orbiting scroll.

[0004] On the other hand, the scroll c...
