Benefits of technology

[0043]As described above, according to the present invention, the power transmission elements for operating the pistons may be disposed within a gear box outside the cylindrical housing to improve the mechanical strength of the rotational pistons and to superiorly cope with the high-temperature high-pressure environment in the fluid.
[0044]Also, according to the present invention, the crank arm may be integrated with the crankshaft, but not integrated with the cylinder, to increase the coupling strength of the crank arm. Also, the one rotational piston may be dispersed into the two rotation pins to operate, thereby improving the power transmission efficiency and the mechanical strength.
[0045]Also, according to the present invention, the non-uniformly rotated two rotational pistons may be combined with each other to change the volume of the chamber, thereby suctioning and compressing the fluid. In addition, the housing and the rotational pistons may completely surface-contact each other to significantly reduce the abrasion and improve the durability and efficiency.
[0046]Also, in the typical vacuum pump, although the vane pump, piston type pump, and water seal type (a centrifugal type) pump are widely used as the vacuum pump, the pump should be more complicated and increased in processing accuracy so as to increase a degree of vacuum. However, according to the present invention, the various pumps may be replaced to effectively realize the degree of vacuum with a more simplified structure and small size.
[0047]Also, according to the present invention, various gas compressors may be small-sized and lightweight to perform a function of a high-pressure positive displacement compressor by using a compressor having a simplified structure such as the vane type compressor. Thus, the present invention may provide a new positive displacement blower having a significant small size and simplified structure as a blower which is capable of replacing the representative positive displacement roots blower to generate the same amount and pressure of wind.
[0048]Also, the present invention has advantages such as the simplified structure and sealing maintenance in flow meter properties. Thus, the flow meter according to the present invention may replace the gear type flow meter, the piston type flow meter, and the diaphragm type flow meter which are widely used as the existing positive displacement flow meter to provide a small-sized structure in which a loss of a pressure is reduced, and measuring accuracy is improved.
