Problems solved by technology

[0003] However, since the blades in contact with the rollers of this rotary compressor are separated into first blades and second blades, the outer surface of the rollers that contact the critical portion of the first blades and the second blades may be severely worn when used for a long time.

Embodiment Construction

[0018] Hereinafter, preferred embodiments provided according to the present invention will be described in detail with reference to the accompanying drawings.

[0019] Figure 1 to Figure 5 It shows the variable capacity rotary compressor provided according to the first embodiment of the present invention. The variable capacity rotary compressor of the first embodiment such as figure 1 As shown, it includes an electric motor mechanism 20 disposed on the inner upper portion of the sealed container 10 , and a compression mechanism 30 disposed on the inner lower portion of the airtight container 10 and connected to the electric motor mechanism 20 through a rotating shaft 21 .

[0020] The electric mechanism 20 includes a cylindrical stator 22 fixed on the inner surface of the sealed container 10 , and a rotor 23 rotatably disposed inside the stator 22 and coupled to the rotating shaft 21 at its center. Such a motor mechanism 20 rotates a rotor 23 when power is applied, and the ...

Abstract

The invention discloses a variable capacity rotary compressor capable of preventing severely wearing of a roller exterior surface. The variable capacity rotary compressor comprises crusts of a first and second compressing chambers which are divided by each other; a first and second rollers arranged respectively inside the first and second compressing chambers; a first vane for setting off the first compressing chamber according to a radial advancing and retreating of the first roller; a second and third vanes slidely supported with each other for setting off the second compressing chamber according to a radial advancing and retreating of the second roller; a vane controller for restricting or releasing the third vane and for controlling the compressing volume; wherein the second vane comprises an extension part extended for covering a front end of the third vane.

Description

technical field [0001] The present invention relates to a variable capacity rotary compressor, in particular to a variable capacity rotary compressor which can change the compression capacity by controlling the advance and retreat of blades. Background technique [0002] Korean Laid-Open Patent Publication No. 10-2004-0021140 discloses a variable-capacity rotary compressor that can change the compression capacity by controlling the advance and retreat of the blades. This rotary compressor includes a casing that forms a cylindrical compression chamber, rollers that rotate eccentrically in the compression chamber of the casing, and blades that advance and retreat in the radial direction of the rollers. The vanes are composed of a first vane on the upper part and a second vane on the lower part which are separated from each other. A constraining unit for constraining the first vane is provided on the side of the first vane as required, so that the first vane and the outer surfa...
