Problems solved by technology
[0002] In the related technology, the high-temperature and high-pressure refrigerant gas discharged from the compression chamber of the cylinder by the rotary compressor will be directly discharged into the compressor shell through the exhaust channel of the upper bearing, which will cause the temperature in the compressor shell to be high and affect the motor and refrigeration. Oil reliability has an impact
[0003] In order to solve the above problems, some compressor structures will discharge the high-temperature and high-pressure refrigerant gas discharged from the compression chamber of the cylinder into the cavities in the upper and lower bearings, but this will cause a large structure of the pump body, a large weight of the compressor, and difficulty in manufacturing. high

The invention discloses a rotary compressor. The rotary compressor comprises a casing and a compression mechanism, wherein the compression mechanism comprises a cylinder having a cylinder hole penetrating through the height along the center axis, an upper bearing arranged at the upper end of the cylinder, and a lower bearing arranged at the lower end of the cylinder, wherein the inner wall of the cylinder hole, the upper bearing and the lower bearing define a cylinder cavity for accommodating a piston; the cylinder is provided with an intake port and an exhaust port communicated with the cylinder cavity; an exhaust cavity is formed in the cylinder, and is communicated with the internal of the casing or the external of the casing; and a communicating channel is formed in the compression mechanism, and is used for communicating the exhaust port with the exhaust cavity. As the exhaust cavity is formed in the cylinder of the rotary compressor, the compressor is simple and compact in structure and excellent in performance.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor. Background technique [0002] In the related technology, the high-temperature and high-pressure refrigerant gas discharged from the compression chamber of the cylinder by the rotary compressor will be directly discharged into the compressor shell through the exhaust channel of the upper bearing, which will cause the temperature in the compressor shell to be high and affect the motor and refrigeration. Oil reliability is affected. [0003] In order to solve the above problems, some compressor structures will discharge the high-temperature and high-pressure refrigerant gas discharged from the compression chamber of the cylinder into the cavities in the upper and lower bearings, but this will cause a large structure of the pump body, a large weight of the compressor, and difficulty in manufacturing. high. Contents of the invention [0004] The present invention ai...
