Abstract

Disclosed is a micro pump that uses magnetic fluid or magneto-rheological fluid to drive a working fluid, comprising an accommodating chamber and at least one body coupled to an opening of the accommodating chamber. The body is provided with magnetic fluid/magneto-rheological fluid and magnetic field generation unit wherein the characteristics of the magnetic fluid/magneto-rheological fluid, which after being solidified upon magnetization is a attracted by the magnetic field, is employed to induce deformation or displacement of the magnetic fluid/magneto-rheological fluid for driving the working fluid and controlling the working fluid to flow into and out of the accommodating chamber and thus effecting quantitative control of flow rate and eliminating the problem of reversed flow.
