Embodiment

[0019] Example: such as figure 1 As shown, the flexible rotor 2 is an integral structure made of flexible elastic material, such as image 3 As shown; the outer surface of multiple flexible rotor bodies F in the radial direction of the flexible rotor 2 is tangent to the circular cavity of the pump body 1 and forms 4 tangent points A, B, C, D; the flexible rotor 2 makes the pump body 1 circular The cavity is divided into 4 independent chambers, namely I, II, III, and IV, such as figure 1 shown. When the main shaft 7 drives the flexible rotor 2 to rotate around O2 in the direction shown in the figure, the volumes of several independent closed chambers change periodically from small to large and then from large to small. The gas medium is sucked through the suction port 3 and discharged through the discharge port 4 The gas medium is inhaled through the suction port 3 and discharged through the discharge port 4 through periodic and constant changes; the working process of pumpin...
