Patent ID: 8876494

Claim:
A compressor, comprising: a hermetic container including a suction tube, through which a refrigerant is sucked inside of the hermetic container; a stator secured within the hermetic container that generates a rotating electromagnetic field inside the stator; a cylinder type rotor that is rotated within the stator by the rotating electromagnetic field of the stator, and defines a compression chamber inside; a roller that rotates within the compression chamber of the cylinder type rotor by a rotational force transferred from the cylinder type rotor, and compresses the refrigerant during rotation; a vane that divides the compression chamber into a suction region, into which the refrigerant is sucked, and a compression region, in which the refrigerant is compressed and discharged from, wherein the vane transfers the rotational force from the cylinder type rotor to the roller; a rotational shaft that is integrally formed and rotated together with the roller, and that extends in an axial direction; and a suction passage, through which the refrigerant is sucked into the compression chamber through the rotational shaft and the roller, wherein the suction passage is separated from the suction tube by a region of open space within the hermetic container.
