Patent ID: 8858205

Claim:
A compressor, comprising: a hermetic container into and from which a refrigerant is sucked and discharged, respectively; a stator fixed in the hermetic container; a first stationary member including a stationary shaft having a top end immovably installed in the hermetic container and being elongated into the hermetic container, and an eccentric portion eccentrically formed on the stationary shaft; and a rotary member including a cylinder-type rotor that rotates around the stationary shaft by a rotating electromagnetic field from the stator, a roller applied with a rotational force of the cylinder-type rotor, that rotates around the eccentric portion with the cylinder-type rotor, and defines a compression space between the roller and the cylinder-type rotor, a vane that transfers the rotational force from the cylinder-type rotor to the roller and partitions the compression space into a suction pocket into which the refrigerant is sucked and a compression pocket in and from which the refrigerant is compressed and discharged, respectively, and upper and lower bearing covers that form upper and lower portions of the compression space and rotate around the stationary shaft with the cylinder-type rotor, wherein an inlet port through which the refrigerant is sucked into the compression space is provided in either the upper or lower bearing cover, wherein the inlet port is formed to overlap with the cylinder-type rotor, and wherein a groove-shaped suction guide portion is formed in a portion of the cylinder-type rotor which overlaps with the inlet port.
