Problems solved by technology
However, the conventional rotary compressor operates constantly 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 in response to changes in ambient temperature, resulting in wasted energy

Embodiment Construction
[0026] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
[0027] figure 1 It is a longitudinal sectional view showing the internal structure of a variable capacity rotary compressor according to an embodiment of the present invention. Such as figure 1 As shown, the variable capacity rotary compressor includes: a driving unit 20 disposed in a hermetically sealed container 10 for generating rotational force; and a compression unit 30 compressing gas using the rotational force of the driving unit 20 . The driving unit 20 includes: a cylindrical stator 22 provided in the hermetically closed container 10; a rotor 23 rotatably provided in the stator 22; and a rotating shaft 21 extending from the center of the rotor 23 ...

A variable capacity rotary compressor, can prevent locking pins from fluff from fixed holes because of the minor vibration generated during the operation time of the rotating compressor. The rotary compressor includes: upper and lower compression chambers; a rotating shaft; an upper and a lower eccentric cams mounted to the rotating shaft; an upper and a lower eccentric bushings respectively set up on the upper and lower eccentric cams; a slot between the upper and the lower eccentric bushings; and locking pins 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 locking pins are provided with locking protuberances, which extend in an opposite direction of the fixed direction. The fixed holes are provided with locking chutes, wherein the locking protuberances engage in them, when the locking pins are fixed in the fixed holes, the locking pins will not rotate along the fluff direction. Therefore, when a slight vibration is transferred to the locking pins, the locking pins will not fluff from the fixed holes.
Description
technical field [0001] The present invention relates to a rotary compressor; and more specifically, the present invention relates to a variable capacity rotary compressor capable of operating two Compression is selectively performed in one of the six compression chambers, thereby varying the capacity of the rotary compressor. Background technique [0002] A refrigerating device, such as an air conditioner or a refrigerator, that cools an environment using a refrigerating cycle, has a compressor that compresses refrigerant circulating in a closed circuit of the refrigerating cycle. The refrigerating capacity of this refrigerating device can be set according to the compression capacity of the compressor. Therefore, when the compression capacity of the compressor is variable, the refrigeration device preferably works according to the difference between the ambient temperature and the set temperature, thereby effectively cooling the environment. Therefore, energy consumption c...
