Abstract
Rotary pump, characterized in that it is constituted by a box, of appropriate shape and dimensions and provided with fixing means on the work surface, inside which a cylindrical enclosure is formed, to which the pipes lead inlet and outlet of the fluid to be transported, and inside which an eccentric shaft is mounted with respect to its contour, to which is attached a piece of elastic material of which a plurality of fins of the same material are extended, which by virtue of the eccentricity of the aforementioned axis is forced, at a point of its rotation comprised between those inlet and outlet of the fluid, to flex against the wall of the housing, determining, respectively, the suction and expulsion thereof through the indicated points .
