Abstract

The invention discloses a rotary compressor, which comprises a crankshaft of the compressor, a compressing structure part, an upper bearing, a lower bearing and a motor driving part, wherein the crankshaft of the compressor is arranged in a casing and is provided with an eccentric part, the compressing structure part is used for compressing coolant gas, the upper bearing and the lower bearing are respectively arranged at the upper side and the lower side of the compressing structure part, the motor driving part is used for driving the compressing structure part, the upper part of the casing is provided with an upper cover, the crankshaft upwards extends, the upper end of the crankshaft is arranged in a bearing arranged under the upper cover, a cylindrical gas-liquid separator is arranged on the crankshaft arranged between the bearing and a rotor, the diameter of the gas-liquid separator is smaller than that of the rotor, at least one exhaust opening is arranged on the outer peripheral surface of the upper part of the casing, and a filter screen is arranged between the exhaust opening and the gas-liquid separator. The rotary compressor of the invention separates small oil drops carried in gaseous coolants through the gas-liquid separator and the filter screen, and reduces the oil outlet quantity of the compressor.

Description

technical field [0001] The present invention relates to compressors, in particular to a rotary compressor. Background technique [0002] Rotary compressors usually eccentrically combine the roller ring of the compression structure part on the crankshaft combined with the motor drive part, and the roller ring rotates in the compression space of the circular cylinder to suck, compress and discharge the refrigerant. [0003] The structure of the existing rotary compressor is generally as follows figure 1 As shown, it includes: a housing 1, a crankshaft 4 of the compressor with an eccentric part arranged in the housing 1, a mechanical structure part, a motor drive part and a compressor structural part. Wherein, the motor driving part includes: a motor stator 2 and a motor rotor 3 arranged inside the housing 1, and the center of the motor rotor 3 is press-fitted and installed on the crankshaft 4; the compression structure part includes: The circular cylinder 5 fixedly arranged ...
