The claimed invention relates to rotary pumps. The claimed rotary pump comprises: an hollow housing having a side wall and end-face walls; a shaft rotatably positioned in the housing essentially in parallel with the side wall, the distance between the housing side wall and the shaft is variable; deformable rollers that are arranged and adapted to move, when the shaft rotates, between the housing side-wall and the shaft, while moving their deformation being maximal in the region of the minimal distance between the housing side-wall and the shaft; and sealed cavities, each of which cavities being defined by two contiguous rollers, the housing's side wall and end-face walls; the sealed cavities being adapted to communicate with the suction port as their volume increases, and communicate with the delivery port as their volume decreases. The technical result: an enhanced delivery capacity—with simultaneous decrease in dimensions and mass; an improved cost-effectiveness, extended longevity and more simple operation. |
