REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Patent Application No. 2005-5333, filed on Jun. 21, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a compressor, and more particularly, to a structure of a compressor capable of reducing vibration and noise from an internal structure of the compressor. [0004] 2. Description of the Related Art [0005] Generally, a compressor includes a driving part for rotating a rotation shaft fixed to a rotor caused by electrical interaction between a stator and the rotor to generate a driving force, a compressing part for compressing a fluid using the driving force, and a sealed case for protecting the components such as driving part, the compressing part, and the like and forming an external appearance of the compressor. Compressors are grouped into a reciprocation type compressor, a rotary type compressor, and a scroll type compressor. [0006] FIG. 1 shows an example of the reciprocation type compressor from among the above-described compressors. As shown in FIG. 1, the reciprocation type compressor includes a sealed case 1 having a predetermined internal space, a driving part 2 installed in the sealed case 1 to generate a driving force, and a compressing part 3 for compressing a fluid. The sealed case 1 is made by coupling an upper case 1a with a lower case 1b. [0007] In this compressor, when the driving force is generated from the driving part 2, when the driving force is consumed by the compressing part for the compression, and when a fluid is compressed and the compressed fluid is discharged, a great deal of vibration and noise is generated, some of which can be eliminated by a vibration absorbing device and a noise absorbing device. [0008] However, when a rate of rotation of the rotation shaft in the compressor is gradually increased, frequency of vibration generated from the internal structure of the compressor may become the same as the natural frequency of the sealed case, resulting in a resonant state so that the vibration and noise are maximized. [0009] When the vibration and noise is transmitted to the exterior of the compressor, the impact on a user is increased and the life span of the compressor is decreased. [0010] Moreover, in order to reduce vibration and noise from an already assembled compressor, a new sealed case is made of a material and a shape different from the sealed case of the already assembled compressor or a separate vibration absorber is attached to the already assembled compressor. However, those arrangements are complicated, time consuming, and require a great deal of costs. SUMMARY OF THE INVENTION [0011] The present invention has been made in- view of the above-mentioned problems, and an aspect of the invention is to provide a compressor in which the natural frequency of a sealed case is changed to prevent resonance of the compressor, to prevent vibration and noise from maximizing even when the compressor rotates at a high rotation speed, and to simply reduce vibration and noise from an already assembled compressor. [0012] In accordance with one aspect, the present invention provides a compressor, which included a sealed case, an internal structure having a driving part provided in the sealed case to generate a driving force to compress a fluid, and a compressing part for compressing the fluid, and a weight provided in the sealed case having a predetermined mass to reduce vibration and noise generated by the internal structure. [0013] Preferably, the weight includes a neck portion extended from a contacting part contacting the sealed case and being bent, and a free end portion formed by bending the neck portion and spaced apart from the sealed case. [0014] The free end portion is preferably bent and a part thereof is preferably welded to the sealed case. [0015] Moreover, the weight could have a predetermined area and be fixed to the inner surface or the outer surface of the lower side of the sealed case. [0016] The neck portion is preferably provided with a spring, the weight could have a welding part to be welded to the sealed case by a spot welding, and the neck portion could be thinner than the free end portion. [0017] With those and other objects, advantages and features of the invention that may become hereinafter apparent, the nature of the invention may be more clearly understood by reference to the following detailed description of the invention, the appended claims and to the several drawings attached herein. BRIEF DESCRIPTION OF THE DRAWINGS [0018] FIG. 1 is a drawing of a cross sectional view illustrating a prior art compressor; [0019] FIG. 2 is a drawing of a partial cross sectional view illustrating a lower case of a compressor to which a weight is attached according to a preferred embodiment of the present invention; [0020] FIG. 3 is a drawing of several partial cross sectional views of the weight of the compressor according to the preferred embodiment of the present invention, in which FIGS. 3a, 3b, 3c, and 3d are views illustrating respective weights of compressors according to first, second, third, and fourth embodiments of the present invention; Continue reading about Compressor...
