Rotation 7: 2 The two rotors are coupled to each other and are tightly moved by a threaded blade to couple a corresponding groove on the other rotor with one rotor blade to form a series of volume changes between the j rotors. During the continuous rotation of the rotor, the gas is compressed gradually through the continuous change of the volume between the blades, and finally the compressed gas is directed to the opposite end of the casing = the rotor is placed on the rotor, and one side is provided with a shaft To the moving spool valve, by adjusting the axial position of the spool valve, the ratio of the exhaust gas valley of the compressed gas can be determined; and at the end of the spool valve, a check valve block for adjusting the axial position thereof is provided. A conventional screw compressor is disclosed in the U.S. Patent No. 5,490, the disclosure of which is incorporated herein by reference in its entirety by U.S. Pat. The convex 201102509-shaped bushings 11, 21 mainly provide a shaft through which the rotor passes, and serve to assist in positioning the check block 'to stabilize the position of the spool. Referring to FIG. 1B, the chevron bushings 1:1 and 21 include a flat plate 12, 22 and a convex pipe portion 13, 23 extending outward from one end of the flat plate. The bushings 11 and 21 are provided at the center. The perforations 14, 24 are passed through the shaft of the rotor. However, it has been found through the squatting manufacturing test that the convex bush portion 13 having a lateral depth is additionally formed on the side end surface of the flat plate. In this way, the convex bushing η is not only required to simultaneously consider the concentric circle problem of the outer diameter of the flat plate and the outer diameter of the convex portion, but also increases the difficulty of processing, and easily affects the outer diameter of the flat plate and the gap between the valve blocks. Control, which in turn affects the stability of the stop block. In addition, as disclosed in U.S. Patent No. 6,409,490, the valve block 25, which is located at the other end of the spool valve 20, is urged by a fulcrum provided at its circle 2 because the fulcrum 1 〇 is located at the stop The center of the block 25 cannot be regarded as a mechanism for preventing the valve block from shaking or rotating, so that when the fulcrum 10 pushes the check valve block 25 to be displaced, the check valve block 25 can easily sway during the shifting process. The compressor is therefore prone to abnormal noise, and in severe cases, the valve block and the rotor interfere with each other. SUMMARY OF THE INVENTION The inventors have in view of the above-mentioned shortcomings of the prior art, and have been involved in the manufacturing experience and technical accumulation of various types of grinding machines, and the above-mentioned deficiencies are known to 201102509. Studying the various methods of solving the problem, in the improvement of morality, the desire for the study, the examination and the lack of the production. (4) Therefore, the main purpose of the present invention is to provide螺 疋 χ χ ^ ^ ^ ^ ^ 〇 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀 阀The improvement of the machine volume ratio adjusting mechanism's stop valve block is driven by an eccentrically set fulcrum, and fits on the flat type pad provided at the stop block end, because the flat: type pad and the stop block can be easily controlled. The gap between them can ensure the displacement of the valve block. There is no sloshing when it is made. The control of the volume ratio is easier to be sure. It is hoped that the noise will not produce abnormal sound, which is the second object of the present invention. The improvement of the volume ratio adjustment mechanism of the screw compressor, by changing the pad to the flat type, the pad can only be processed when considering the size of the outer diameter. The processing is relatively simple and the tolerance control is more precise. Too many combinations need to be considered when machining a zigzag bushing: The problem of the difference accumulation is another object of the invention. The improvement of the volume ratio adjusting mechanism of the screw compressor according to the invention 'Because the pad is changed to the flat type, the pad can directly serve as the interface component of the rotor end face and the inner wall of the rotor Since the function of the pad is only the effective clearance of the fixed and holding and stopping valve blocks, if the error is too large due to machining deviation under the premise of easy processing, the thickness of the block can be adjusted by the thickness of the block. The gap between the rotors and the improvement of the compressor efficiency 201102509 rate' is another object of the present invention. _ The improvement of the volume ratio adjusting mechanism of the screw compressor according to the present invention is improved by the pad type for the easy processing. When the machine is in contact with the rotor and the flat type pad, the gap between the rotor and the flat plate can be directly replaced, which can eliminate the cost and inconvenience that the reader must replace the compressor casing, which is another object of the present invention. The responsible review committee can make a further understanding and understanding of the purpose, shape, structure and function of the present invention, and the embodiments are combined with the drawings to explain in detail Next: [Embodiment] Improvement of the volume ratio adjusting mechanism of the screw compressor of the present invention As shown in Fig. 2, the screw compressor 3 has two rotor shaft holes 31, 32 inside the casing to After the male rotor 41 and the female rotor 51 are provided (as shown in Fig. 3), the male rotor 41 and the female rotor 51 are rotated by the grooves and the rotary blades. Referring to Fig. 4, the male rotor is shown. Before the female rotor 51 and the female rotor 51 are housed inside the screw compressor 3, at the front end of the inner wall of the rotor chamber 30, that is, at the rotor suction holes 31, 32, a bushing 42 for attaching to the wall surfaces of the shaft holes 31, 32 is provided. 52 (as shown in Fig. 5). As shown in Fig. 6, the bushings 42, 52 are in the form of a flat plate having a non-circular surface, and each of the pair of seats forms a circum 421, 521. The through holes 422, 522 are disposed therebetween, and the through holes 422, 522 and the rotor shaft holes 31, 32 communicate with each other, so that the rotating shafts of the male rotor 41 and the female rotor 51 201102509 are simultaneously fixed through the through holes 422, 522 and the rotor shaft holes 31, 32. . As shown in Fig. 5, when the bushings 42, 52 are mounted and fixed to the inner wall surface of the rotor, they maintain a relatively small gap with the check valve block 6. However, since the bushings 42 and 52 have a flat design, it is only necessary to consider whether the distance from the check valve block 6 is kept within the standard gap during processing, and it is difficult to manufacture and process compared with the conventional chevron bushing. Tolerance/empty, etc. are all simplified. Therefore, the flat bushings 42 and 2 are known to provide the advantage of the easy positioning of the valve block 6 by the valley. Referring to Fig. 4, the improvement of the volume ratio adjusting mechanism of the screw compressor of the present invention further makes it possible to adjust the stop block 6 position = the support shaft 6! When the yaw-set fulcrum I is pushed to move the stop slider 6, the problem of easy production of the center of the core can be avoided, and the stability of the block 6 is further provided. Therefore, by providing the check valve block 6 through the flat type as described above, the accuracy of the spool control can be improved regardless of whether the front and the rear are turned (cut). There is no movement, and it is noted that, due to the bushing 42 and the type, the rotor end portion and the Korean sub-section are adjusted for the thickness of the flat plate. Even when: fine by the bushing due to improper use or external force 01$ during use, the external force factor causes the rotor end
