Problems solved by technology
However, conventional rotary compressors perform constant operation with a fixed compression capacity regardless of the difference between the ambient temperature and the set temperature
As a result, conventional rotary compressors do not operate optimally according to the temperature of the environment and energy is wasted as a result

Embodiment Construction
[0023] The present invention will now be described in detail with reference to the accompanying drawings, wherein like reference numerals indicate like elements. The embodiments will be described in detail below with reference to the accompanying drawings.
[0024] figure 1 is a longitudinal cross-sectional view of the internal structure of the variable displacement rotary compressor according to the embodiment of the present invention. Such as figure 1 As shown, the variable displacement rotary compressor includes: a driving unit 20 disposed in a hermetic container 10 for generating rotational force; and a compression unit 30 for compressing gas by the rotational force of the driving unit 20 . The driving unit 20 includes: a cylindrical stator 22 provided in the hermetic container 10; a rotor 23 rotatably provided in the stator 22; and a rotating shaft 21 extending from the center of the rotor 23 to perform forward Rotate (in the first direction of rotation) or counter-rot...

A variable capacity rotation compressor with a bolt firmly fixed in the fixed holes of the rotation axis, includes an upper and a lower compression chambers with different capacities; a rotating shaft; an upper and a lower eccentric cams matched to the rotating shaft eccentricall from the rotating shaft in the same direction; an upper and a lower eccentric bushings respectively set up on the circumference of the upper and lower eccentric cams, which face to each other through the largest eccentric part of the upper and lower eccentric cams; a slot limiting between the upper and the lower eccentric bushings; and bolts fixed in the fixed holes formed in the rotation axis, for selectively switching the upper and lower eccentric bushings to a maximum eccentric rotation position. The said bolts include elliptical cross-section heads. The head part of the said bolts has a greater diameter part, and the diameter of the larger diameter part is about 0.02 mm-0.06mm larger than the diameter of the fixed holes, these heads connected to the fixed holes throught threads. The main part of the bolts is connected to the fixed holes throught threads. As a result, when a smaller vibration or shock is transferred to the bolt, the bolt will not fluff from the fixed holes.
Description
technical field [0001] The present invention relates to a rotary compressor, and more particularly, to a variable displacement rotary compressor capable of selectively performing compression in one of two compression chambers having different capacities by an eccentric unit provided on a rotary shaft, thereby varying the rotation The capacity of the compressor. Background technique [0002] A cooling device for cooling an environment by a refrigeration cycle, such as an air conditioner or a refrigerator, has a compressor that compresses a circulating refrigerant in a closed circuit of the refrigeration cycle. The cooling capacity of such a cooling device is set based on the compression capacity of the compressor. As a result, when the compression capacity of the compressor is variable, the cooling device operates optimally based on the difference between the ambient temperature and the set temperature, so that the environment can be efficiently cooled. As a result, energy ...
