Patent ID: 8905734

Claim:
A compressor, comprising: a shell having a sealed internal space; a stator fixed and installed in the internal space of the shell; a rotor rotatably provided with respect to the stator to be rotated with the stator; a cylinder coupled with the rotor to be rotated with the rotor, the cylinder having a rotational center, a top, and a bottom; a plurality of bearings that cover the top and the bottom of the cylinder to form a compression space with the cylinder, the plurality of bearings including an upper bearing and a lower bearing; a stationary shaft fixed in the internal space of the shell, a shaft center of the stationary shaft being coaxial to the rotational center of the cylinder, and an eccentric portion of the stationary shaft varying a volume of the compression space during rotation of the cylinder while supporting the plurality of bearings in an axial direction of the plurality of bearings; a refrigerant suction passage that guides refrigerant into the compression space; an accumulator having an accumulating chamber formed by an accumulator frame coupled to the shell, the accumulator frame being sealed with respect to the shell so that the accumulator frame air-tightly separates the accumulator chamber from the internal space of the shell, wherein a suction pipe communicates with the accumulating chamber, and wherein an end of the stationary shaft is inserted into and coupled with the accumulator, such that a suction passage of the stationary shaft communicates with the accumulating chamber; and an oil collecting plate installed on the upper bearing, located on the top of the cylinder, the oil collecting plate collecting oil and distributing it between the cylinder and the eccentric portion, wherein each of the plurality of bearings is formed with a shaft receiving portion having a shaft receiving hole configured to rotatably receive the stationary shaft inserted therein, and wherein the oil collecting plate comprises an oil collecting portion that surrounds an upper side of the shaft receiving portion and an oil guide portion that guides the collected oil to between the cylinder and the eccentric portions.
