Problems solved by technology

[0007] However, the load received by the rollers from the compressed refrigerant inside the cylinder is not constant but varies according to the rotation angle of the rollers. In conventional compressors, the welded portion is formed at any position, so the The welded portion cannot sufficiently support the maximum load acting on the combined body at the moment when the maximum load is applied

Embodiment Construction

[0017] Hereinafter, a rotary compressor according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0018] Such as figure 1 As shown, the rotary compressor provided according to the preferred embodiment of the present invention is composed of a shell 10 forming a shape, a driving part 20 and a compressor 30 inside the shell 10 . One side of the housing 10 is connected to a suction pipe 12 that supplies an operating fluid from an accumulator 11 for filtering out liquid refrigerant to the compression part 30 .

[0019] In addition, a discharge pipe 13 for discharging compressed fluid is provided on the upper part of the casing 10, and a certain amount of lubricating oil 14 is filled in the lower part of the casing for lubricating and cooling the friction-moving parts.

[0020] The driving unit 20 is composed of a stator 21 fixed to the casing 10 , a rotor 22 rotatably supported inside the stator 21 , an...

Abstract

Disclosed is a rotary compressor which can remarkably reduce the libration during the operation period. The rotary compressor according to the invention is characterized by being provided with: a casing forming a closed inner room; a cylinder disposed inside of the casing with an inner room; a rotary shaft through the cylinder; a roller arranged inside of the cylinder for compressing the operation liquid by eccentricly rotating; a flange for sealing the cylinder and supporting the shaft; a combination for connecting the cylinder with the flange; a plurality of fixing members disposed on the outer of the combination for fixing the combination; the first fixing part is installed on a position wherein the combination bearing a maximal counterforce, generated from compressing the operation liquid in the cylinder by the roller.

Description

technical field [0001] The present invention relates to a rotary compressor, and more particularly to a fixing part for fixing a shell and a combined body combined with a cylinder and an upper flange for sealing the interior of the rotary compressor. Background technique [0002] Generally, a compressor is a device that pressurizes fluid such as air or refrigerant after receiving power from a driving device such as a motor, compresses and discharges the compressed fluid, and is used in various products such as air conditioners and refrigerators. [0003] Among such compressors, there is a rotary compressor in which fluid is compressed by eccentrically rotating rollers inside the cylinder. An example of such a rotary compressor is disclosed in Japanese Laid-Open Patent Publication No. 60-201095 . [0004] As disclosed in the above-mentioned documents, the inside of the housing for sealing the interior of the rotary compressor includes: a cylinder as ...
