Problems solved by technology

[0004] However, such a rotary compressor may suffer from a decrease in compression efficiency because the gas on the high-pressure side inside the compression chamber leaks to the low-pressure side through the gap between the rollers and the surface of the compression chamber.
That is, since there is a gap between the outer surface of the roller and the inner surface of the compression chamber, there is a limitation in improving the compression efficiency

Embodiment Construction

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

[0019] According to the rotary compressor provided by the present invention such as figure 1 As shown, it includes a transmission unit 20 arranged at the inner upper part of the airtight container 10 and a compression unit 30 arranged at the inner lower part of the airtight container 10 and connected with the transmission unit 20 through a rotating shaft 21 .

[0020] The transmission unit 20 includes a cylindrical stator 22 fixed to the inner surface of the airtight container 10 , and a rotor 23 rotatably provided inside the stator 22 and having a central portion coupled to the rotating shaft 21 . When the transmission unit 20 is powered on, the rotor 23 rotates, thereby rotating the shaft 21 connected to the compression unit 30 .

[0021] like figure 1 and image 3 As shown, the compression unit 30 has an outer cover, which includes...

Abstract

The invention discloses a rotary compressor which makes the clearance minimum between the internal surface of the compression chamber and the outer surface of the roller, wherein the rotary compressorhas a case of the compressor, a shaft ratating in the compressor, an eccentric part combined with the shaft inside the compressor and a roller rotaryly combined on the outer surface of the eccentricpart slidingly combined with the shaft used for moving along the directions different from the self eccentric direction.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a rotary compressor which improves compression efficiency by reducing the gap between the inner surface of the compression chamber and the outer surface of the roller. Background technique [0002] The rotary compressor disclosed in Japanese Patent Publication No. Hei 4-255592 includes a cylinder block for defining a compression chamber, upper and lower flange covers respectively coupled to the upper and lower parts of the cylinder block, and rollers rotating eccentrically in the compression chamber. Sub, flat blades that advance and retreat in the radial direction as the rollers rotate to divide the compression chamber into a suction-side space and a discharge-side space. [0003] In this rotary compressor, the rollers rotate eccentrically along the inner surface of the compression chamber to perform the compression action. In order to avoid excessive friction between the rollers and the i...
